Two field experiments were conducted at a Private Farm near Aga, Dakahlia Governorate during two successive winter seasons of 2012/2013 and 2013/2014 to investigate the effect of bio-fertilizers inoculation method, some foliar application treatments and their interactions on vegetative growth characters, chemical constituents, yield and quality traits of pea (Pisum sativum L.). Four inoculation methods of bio-fertilizers (mixture of Rhizobium leguminosarum, Bacillus megatherium and Bacillus circulans) , i.e, without inoculation, seeds inoculation pre-sowing, soil inoculation after germination and dual inoculation (seeds plus soil) and four foliar application treatments (control, seaweed extract at 2.5 ml/l, ascorbic acid at 200 ppm and yeast extract at 5 g/l). The data were recorded for yield and its components (pod length, pods weight/plant, No. of pods/plant, No. of green seeds/pod, weight of 100 green seeds and total yield/ fed.). Chemical constituents (N, P and K%) in leaves and pods. Pods quality (carbohydrates, crude protein, reducing, non reducing sugar and total sugar).
Obtained results showed that dual inoculation (seeds pre-sowing and soil after germination) combined with yeast extract as a foliar application surpassed other treatments in yield and its components, pods quality parameters and chemical constituents of leaves and pods.

Two field experiments were carried out in a private farm at Gamassa district, Belqas Center, Dakahlia Governorate, Egypt, during the two successive summer growing seasons of 2013 and 2014 to study the effect of mineral nitrogen fertilizer rates, organic manure and foliar fertilization treatments with biofertilizers , biostimulants as well as their interactions on growth and yield of cantaloupe cv. Primal. The field experiments were laid-out in strip-split plot design with three replications. The most important results obtained from this investigation can be summarized as follows:
Increasing mineral nitrogen fertilizer rates from 75 to 100 and 125 kg N/fed tended to increase growth, yield and its components, thus the highest values of these characters were resulted from adding the highest rate of nitrogen fertilizer (125 kg N/fed) in both seasons.
Organic fertilizing of cantaloupe plants with chicken manure at the rate of 15 m3/fed significantly increased growth, yield and its components as compared with control treatment (without organic manure) in both seasons.
Foliar spraying cantaloupe plants with yeast extract at rate of 5g /1L significantly surpassed other treatments (without, spraying with EM or Agrispon) and produced the highest values of all studied growth, yield and its components in both seasons.
It can be recommended that organic fertilizing cantaloupe with 15 m3 chicken manure/fed and foliar spraying plants with yeast extract and mineral fertilizing with 100 kg N/fed in order to increase cantaloupe yield over the control treatment and reduce the environment pollution and production costs under the environmental conditions of Dakahlia Governorate, Egypt.

This study was conducted during two successive seasons of 2011 and 2012 on Flame Seedless grape cultivar in order to evaluate the effect of citric acid at 2.0g/l and acetic acid at 0.5 cm/l with ethephon at 250 and 500ppm on berry quality and storage ability under cold storage and through marketing at room temperature. Clusters were sprayed at version stage as a pre harvest treatments at the soluble solids content reached about 10 -12%. At full color, clusters were harvested when the soluble solids content in berry juice reached about 16-18 % and held at room temperature conditions or stored under cold storage conditions at 0c±1 and 90-95% relative humidity(R.H) to determine the physical and chemical characteristics of berries during storage period. The results reveal that spray clusters with citric or acetic acid combined with ethephon as pre harvest treatments reduced the total loss of cluster weight due to their effect on reducing decayed berries and berry shatter. Also, citric and acetic acid treatments presented a higher anthocyanin content in berry skins and gave an positive effect on increasing SSC in berry juice.

Eskandarani cultivar to study the impact of phosphorus fertilizer levels 20, 40, 60 and 80 kg P2O5 /fed. and fruit thinning treatments;i.e., without thinning (control) , thinning the first fruit, thinning all fruits except the first and second ones and thinning the first and second fruit and their interaction on vegetative parameters and leaf chlorophyll contents.
Results indicated that, the highest values of vegetative characters; i.e., stem length, plant fresh and dry weight, leaf area/plant and chlorophyll content in leaves in both seasons were recorded when plants fertilized with 80 kg P2O5 /fed. Number of leaves/plant not affected by phosphorus fertilizer levels, in both seasons. Thinning the first and second fruit produced the highest values of stem length, plant fresh and dry weight , number of leaves/plant, leaf area/plant and chlorophyll content in leaves in both seasons. On the other hand, squash plants fertilized with 80 kg P2O5 /fed. with thinning the first and second fruit produced the highest values of stem length, plant fresh and dry weight , number of leaves/plant, leaf area/plant and chlorophyll content in leaves, while, squash plants fertilized by 20 kg P2O5 /fed. with thinning all fruits except the first and second ones produced the lowest value of each character.
According to the mentioned results, the best results of both vegetative growth parameters and chlorophyll contents in leaves were recorded when squash plants fertilized by 80 kg P2O5 /fed. with thinning the first and second fruit ,therefore, this treatment could be recommended for improving squash plants performance under similar condition of this study.

Germination and seedling characters are affected with some factors such as kind, temperature, natural materials, growth regulators, etc. Four plants (Tomato, Eggplant, Cucumber and Cantaloupe) were used in an experiment which was carried out at a greenhouse in Talkha - Dakahlia Governorate during the period from 2012-2013 to study the effect of four supplements Humic acid (HA), Indol-3-buttyric acid (IBA), Lawsonia inerms L. (Lw) and dry Yeast (Y) when each was added to the soil media at a concentrations of 1.0 g/L, 2.5 g/L and 5.0 g/L for HA, Lw and Y but 0.05 g/L, 0.1 g/L and 0.15 g/L for IBA.
The results showed that HA with 1.0 g/L leads to a significant increase in germination percent to tomato, eggplant and cantaloupe in comparison to control group. While addition of Lw with 1.0 g/L to the cucumber seeds gives a significant result compared with the control results. During the estimation of germination velocity, a significant reduction in germination days was obtained with (1.0 g/L HA to tomato, 5.0 g/L HA to cucumber, 0.15 g/L IBA to eggplant and 5.0 g/L Y to cantaloupe). Seedling height measurement shows slight significant results with 1.0 g/L Y to cucumber seeds, 2.5 g/L to tomato seeds and 5.0 g/L to eggplant and cantaloupe.
Seedling leaf area reveals that 1.0 g/L Y to cucumber seeds, 5.0 g/L Y to eggplant seeds, 1.0 g/L Lw to tomato and cantaloupe shows increased results. Results showed also slight significant values of seedling hypocotoyl length with 0.05 g/L IBA to cantaloupe, cucumber and eggplant but 1.0 g/L HA to tomato. Seedling stem neck diameter showed significant increase results with 1.0 g/L of Lw to eggplant, cantaloupe and 2.5 g/L Y to cucumber and 5.0 g/L Y to tomato. A significant values of root fresh weight was obtained by adding 2.5 g/L Y to cucumber, 5.0 g/L Y to (tomato and eggplant( and 0.05 g/L IBA to cantaloupe. Noticed significant results was obtained during measuring shoot fresh weight with 1.0 g/L Lw to tomato and cantaloupe, 5.0 g/L Y to eggplant and 2.5 g/L Y to cucumber. Chlorophyll a estimation showed a significant result with adding 5.0 g/L HA to tomato, 0.15 g/L IBA to eggplant, 1.0 g/L Lw to cucumber and 1.0 g/L Y to cantaloupe. Chlorophyll b refers to a significant increase with 0.15 g/L IBA to tomato and cucumber, 5.0 g/L HA to eggplant and cantaloupe. Total Chlorophyll a and b indicates significance with 5.0 g/L HA to tomato, eggplant and cantaloupe but 1.0 g/L Lw to cucumber.
Generally; it could be concluded that, the effect of some supplements to the growth media of some vegetable transplants crops can improves its quality and characters.

LATE AND EARLY PEDIGREE SELECTION FOR GRAIN YIELD WITH THREE SELECTION CRITERIA IN TWO POPULATIONS IN BREAD WHEAT
K.
Hamam
The present study was carried out during the four successive seasons of 2009/2010, 2010/2011, 2011/2012 and 2012/2013 at the Experimental Farm of Faculty of Agriculture, Sohag University, Egypt. Bread wheat populations (Triticum aestivum L.) in F3, F4, F5 and F6 generations of the (Sids 12 x HAAMA-14) and (Giza 168 x TRI 2592) crosses were used in this investigation. One hundred 3 families of each population, which underwent pedigree selection in the 3 basic material for the derived F6 families used in this study. The aim was to compare the effectiveness of late pedigree selection vs. early pedigree selection in developing high yielding genotypes of bread wheat. Forty families were selected in F4 using grain yield, 100-kernel weight and days to heading as selection criteria. Twenty families were selected in F5 using the same criteria. However, ten families were selected as promising in F6 using late and early selection for grain yield. Analysis of variance showed highly significant differences between F3 families and satisfactory genotypic coefficients of variation, indicating the presence of sufficient variability for direct and indirect selection. After three cycles of selection in the F3 families, the genotypic coefficients of variability rapidly decreased for all studied traits. Estimates of broad sense heritability were relatively high and ranged from 76.73% for no. of spikes/plant to 99.94% for no. of kernels/spike in population 1 and from 72.34% for no. of spikes/plant to 98.61% for no. of kernels/spike in population 2. The expected genetic advance as percent of F3 ranged from 19.70% for days to heading to 94.94% for number of spikes/plant in population 1 and ranged from 23.21% for plant height to 79.24% for spike length in population 2. The late pedigree selection increased grain yield after one cycle of selection in the population compared to the best parent and the bulk population by 12.39 and 25.44% in population1 and by 9.26 and 23.74% in population 2. Grain yield increased after three cycles of early selection of both populations compared to the best parent and the bulk population by (20.66 and 34.67%); (17.08and 32.59%), respectively. 100-kernel weight increased by (11.32 and 24.25%); (7.98 and 22.28%), respectively, in both populations compared to the best parent and the bulk population. The best two families No. 42 and 56 were isolated from population1 increased more than the best parent by 28.58 and 31.52% using selections criteria for grain yield, respectively. In population 2 the best two families No. 52 and 56 increased more than the best parent by 24.74 and 27.60% using selections criteria for grain yield, respectively. After three cycles of selection of wheat realized gains indicated that heading date was reduced by -9.84 and -10.86% compared to the best parent of both populations. The high grain yield families using different criterion obtained from this study could be used in developing new wheat lines and effective for breeding methodology in developing high yielding.

The present study was carried out at the Experimental Farm of El-Quassassin Hort. Res. Station, Ismailia Governorate, Hort. Res. Institute, Agric.Res.Center, Ministry of Agric., Egypt. during the two successive seasons (2010/2011) and (2011/2012) to investigate the effect of water requirements (1150, 2300 and 3450 m3 / fed.) and fertilization treatments (mineral fertilizers NPK (control) at the rate of 300 kg / fed ammonium sulphat, 300 kg / fed super phosphate and 200 kg / fed potassium sulphate), (three sources of organic manure, i.e., poultry manure (PM), compost (C) and cattle manure (CM) at 10,15 and 20 m3 / fed) respectively and their interactions between them on growth, dry ray flowers yield and active ingredient of marigold (Calendula officinales L.) plant using drip irrigation system under sandy soil condition.
Irrigated marigold plants by 3450 m3 / fed water recorded maximum values of plant growth parameters ,i.e., plant height, number of branches / plant, plant fresh and dry weights, yield of dry ray flowers / fed, carotenoides and olenolic acidin flowers of marigold plant as compared to other irrigation treatments. While, the lowest values of these parameters were obtained with 1150 m3 /fed water. On the other side, water use efficiency (WUE) was the highest with 1150 m3 /fed irrigated water in both seasons.
Plant growth parameters and the yield of dry ray flowers/ fed, WUE, carotenoides and olenolic acid content in flowerswere increased significantly with plant fertilization with poultry manure (PM) at 10 m3 / fed.
Interaction treatment between water quantity at 3450 m3 / fed and poultry manure (PM) at 10 m3 / fed or the same rate of irrigation combined with mineral fertilizers was the superior treatments for enhancing plant growth, yield of dry ray flowers and chemical constituents in flowers of marigold plants in both seasons. While the interaction between 1150 m3 / fed water and poultry manure (PM) at 10 m3 / fed was the best treatment for increasing water use efficiency (WUE) in both seasons.
It could be concluded that irrigated marigold plants by 3450m3 water/ fed combined with 10m3 /fed poultry manure (PM)was the best treatment for enhancing plant growth parameters, yield of dry ray flowers, carotenoides and olenolic acid in flowers. On the other side, water use efficiency (WUE) was the higher when irrigated plants with 1150 m3 water / fed combined with 10 m3 /fed poultry manure.

This investigation was carried out in 2012 and 2013 seasons on 2 and 3-year-old Washington Navel orange (WO), Valencia orange (VO) and Balady mandarin (BM) budding on five Citrus rootstocks namely; C. volkameriana (VM), Troyer citrange (TC). Rangpur lime (RL), Cleopatra mandarin (CM) and sour orange (SO) grown in a private farm at Menofia Governorate, Egypt, where the soil is slightly saline alkaline clayey. The results indicated that Valencia orange, Washington Navel oranges and Balady mandarin as scion varieties on C. volkaneriana and Rangpur lime rootstocks are characterized by: higher leaf concentrations of N, K, Ca, Mg, Fe, and Zn, lower C/N, N/K and higher K/Na ratio compared to other rootstocks while, leaf P and Mn showed no consistent trend. Moreover, these rootstocks had higher ability to reduce Na and Cl absorption and its accumulation in leaves of the three scion varieties in contrast to the other rootstocks. Also, they had the least values of leaf miners infection. Generally, the five tested rootstocks could be descending arranged due to their effects on these characters of the three scion varieties (WO, VO and BM) under this study conditions as follow: (VM), (RL), (TC & SO) and finally (CM). Accordingly, both rootstocks (VM & RL) may be considered as suitable substitutes for sour orange in Egypt. This evaluation could be of great impact for nurserymen and citrus growers. It help growers to select the right rootstock for the desired variety in a given area.

Selection for physiological characteristic and evaluation the performance and degree of drought tolerance of the six selected faba bean cultivars and their F1 crosses were tested under two levels of soil moisture. Randomized complete blocks design with three replicates was used in each experiment, (normal & stress environments) during the two growing seasons 2006/07, 2007/08 at North Sinai Research Station, Desert Research Center. The results indicated that significant mean squares due to genotypes were obtained for all characters under both environments and the combined data. The ratio of specific combining ability (S.C.A.) × environment (Env.) /S.C.A. was much higher than ratios of general combining ability (G.C.A.) × environment Env./G.C.A. for all characters except plant height and number of branches. The parental Giza 429 (P4), Giza 716 (P5) and Giza 2 (P6) gave positive and significant (ĝi) for yield and one or more of its components under normal and stress irrigation as well as the combined data. Meanwhile, the cross combination Nubaria 1 (P4) × Giza 429 (P1) appeared to be the best promising hybrid for breeding to increase seed yield per plant which gave significant positive Ŝij for yield and some of its component under both environments as well as the combined data.

Genetic diversity of quinoa around the world is narrow which may threaten the ability of breeders to improve and increase the crop yield. A field experiment was carried out at the experimental farm at Ras Sudr, South Sinai Governorate during growing season 2012/2013. Yield, its components and the genetic variation among five quinoa genotypes viz:Kvlsra 2, Kvlsra 3, Regalona, Q-37 and Q-52 were evaluated under Ras Sudr conditions. The results indicated that the genotype Q-37 followed by Regalona cultivar recorded the highest mean values for seed yield. The correlation for mean performances were positive and high significant among number of heads and each of heads yield, 1000- seed weight, seed yield and straw yield, such traits may be taken in account in quinoa breeding programs.
Biochemical and molecular markers were used to identify the level of polymorphism and to study the genetic relationships among the five quinoa genotypes. Seventeen polymorphic protein bands produced (59%) of polymorphism. Regalona cultivar and Q-37 revealed that highest number of protein unique bands which could be considered as marker for salinity tolerance. Five isozymes systems including POD, ACPH, β-EST, α-EST andADH revealed six polymorphic bands and produced moderate polymorphism (53%) and two unique bands for Q-37 as markers for salinity tolerance. Five RAPD primers produced fifteen polymorphic bands, and produced the highest polymorphism (66%). Q-37 genotype produced the highest number of unique bands as specific band for salinity tolerance. The dendrogram for the genetic relationships of the five quinoa genotypes based on overall markers separated them into two major groups. The first group included Q-37 genotype and Regalona cultivar and the second group were included Kvlsra 2, Kvlsra 3 and Q-52 genotypes.
From the previous results, a considerable level of variations were detected among five quinoa genotypes by biochemical and molecular markers which can help to select the most suitable genotypes Q-37 and Regalona cultivar for stress tolerance, good yield, presented considerable interest for the genetic studies, plant improvement and accepted by farmer to enter breeding programs and for reclamation salt affected lands. The mean squares for all traits were significant among the five quinoa genotypes.

INHERITANCE OF SOME IMPORTANT TRAITS IN SWEET PEPPER (Capsicum annuum L.)
I.
Mahmoud
The present study was conducted at the Experimental Farm, Faculty of Environmental Agricultural Sciences, El Arish, Suez Canal University, Egypt, during three successive summer seasons from 2011 to 2013. The study involved six generations; viz., P1, P2, F1, F2, Bc1 and Bc2 of sweet pepper hybrid (B10-24 x TS 6-3-3). The objective of the present investigation was to study the inheritance of some important traits of sweet pepper. The obtained results showed that difference between the two parents was highly significant for all studied traits. The means of F1 cross was deviated toward the high parent for most characters, while it was similar to that of high parent for average fruit weight. Segregating populations showed greater coefficient of variability (C.V%) than the non-segregating ones for all studied traits. Additive gene effects (d) were significant in the inheritance of all characters, except fruit length, fruit diameter and pericarp thickness. However, dominance gene action (h) was more importance in the inheritance of all studied traits, except number of fruits/plant. Epistasis gene actions were found to be important in the inheritance of most traits. Heterosis over mid-parents was detected in eight characters. However, heterosis over better parent was found, but only in three traits. Inbreeding depression was observed in six characters. Heritability estimates in broad sense (hb) were high for all characters. The minimum number of genes controlling the traits were one pair for plant height, fruit diameter, pericarp thickness, T.S.S, ascorbic acid and total yield/plant, while number of genes were estimated as two to three pairs for number of branches, two to four for fruit length, three to seven for number of fruits/plant and two pairs for average fruit weight.

The present investigation was carried out at the Farm of Sakha Agricultural Research Station, during 2012 and 2013 summer seasons. Combining ability analysis was estimated in rice through a 6 x 6 diallel set analysis involving 6 diverse parents for grain yield and its components and grain quality. Eight yield and its component and eight grain quality characters were studied. Mean square values of parents and crosses and parents vs crosses were found to be highly significant for all characters. Both general and specific combining ability variances were found to be highly significant for all characters, indicating the importance of both additive and non-additive genetic variance in determining the performance of the studied sixteen characters. GCA/SCA ratios were found to be greater than unity for all characters studied except for panicle length, number of filled grains/panicle and gelatinization temperature, indicating that the additive and additive x additive types of gene action were of great importance in the inheritance of all the studied characters except for the three mentioned traits which were controlled by non-additive genetic variance. The genotypes GZ 1368, Sakha106, Sakha 102 and Sakha 103 were good general combiners for most studied characters. Cross combinations involving such parents were superior for most of studied characters. The promising combinations for grain yield along with at least two of yield component characters were GZ1368 x Giza 177, Sakha 106 x Giza 176, Sakha 102 x Giza 177, Sakha 102 x Sakha 106, GZ 1368 x Sakha 103 and Giza 176 x Giza 177. Four crosses Sakha106 x Giza 177, Sakha103 x Giza177, Sakha102 x Giza 176 and Sakha103 x Giza176 showed highly significant and positive SCA for most studied grain quality characters. A greater magnitude of heterosis ranged between 2.38 and 13.88% was observed in seven crosses i.e. Sakha 103 x Sakha 106, Sakha 103 x Giza 176, Sakha 103 x Giza 177, GZ1368 x Giza 177, Sakha 106 x Giza 176, GZ1368 x Sakha 103 and Sakha 102 x Sakha 106 for grain yield /plant and grain quality characters. The availability of sufficient hybrid vigor in several crosses in respect of grain yield suggests that a hybrid breeding program could profitably be undertaken using these materials.
From the foregoing discussion, it may be concluded that the crosses,Sakha 103 x Sakha 106, Sakha 103 x Giza 176, Sakha 103 x Giza 177, GZ1368 x Giza 177, Sakha 106 X Giza 176, GZ1368 x Sakha 103 and Sakha 102 x Sakha 106 can be rated as the best crosses based on their heterosis in most of the studied traits including grain yield. Thus, it can be exploited in subsequent generations to improve most of the studied traits. Four crosses Sakha106 x Giza 177, Sakha 103 x Giza 177, Sakha 102 x Giza 176 and Sakha 103 x Giza 176 could be recommended for growing as hybrid rice.

EFFECT OF PLANT POPULATION AND DISTRIBUTION ON YIELD AND YIELD COMPONENTS OF FIVE FABA BEAN GENOTYPES
Rehab
Abd El-Rahman
Plant population density plays an important role on crop growth and yield as response to light penetration and photosynthesis rate. A field experiment was carried out at Sids Research Station, Agricultural Research Center (ARC), during two successive winter seasons, of 2012/13 and 2013/14. The objectives of this investigation was aimed to evaluate five faba bean genotypes namely Nubaria 1(large seeded cultivar), Giza 429, line 43130, E.19 (medium seeded types) in addition to the small seeded type Camolina. Plant densities were; a) 8 plants/m2 planted in single seeded hills spaced 20 cm on one side of 60 cm wide ridges, b) 17 plants/m2 planted in double seeded hills spaced 20 cm on one side of the ridges, c) 17 plants/m2 planted in single seeded hills spaced 20 cm on both sides of the ridges and d) 33 plants/m2 planted in double seeded hills spaced 20 cm on both sides of the ridges. Results indicated that, faba bean genotypes were significantly different in all studied characters. Nubaria 1 and E.19 genotypes had the tallest plants, respectively. The highest seed yield per feddan was obtained from Nubaria 1 cultivar, while the medium seeded line L-43130 produced the lowest seed yield per feddan over both seasons. Giza 429 (medium seeded cultivar) followed by Nubaria 1. Plant population of 17 plants/m2 in single seeded hills on both sides of the ridges produced highest seed yield per feddan over all genotypes. Concerning to the interaction between plant populations and faba bean genotypes, highest seed yield per feddan was obtained from the large seeded cultivar Nubaria 1 under the low plant population (8 plants/m2), while the medium seeded types i.e. Giza 429, L-43130 and E19 were more yielding under the third plant population (17 plants/m2 on both sides of the ridge). On the other hand, the small seed type Camolina produced highest seed yield per feddan under the high plant population (33 plants/m2). The interaction between faba bean genotypes and plant population had significant effects on all studied characters except number of days to flowering.
