Onion seeds rapidly lose its viability and vigor after short time of harvest, and therefore its germinability largely decline. Consequently, the present investigation was carried out during the period from 2010-2012 in both Plant Tissue Culture Laboratory, Vegetables & Ornamentals Department, Faculty of Agriculture, Mansoura University and greenhouse of a private nursery in production of vegetable transplants, Qlabasho village, El-Dakahlia Governorate to study the effect of Moist-chilling (cold stratification) treatment for four periods (0, 5, 10 and 15 days) at 5 ± 1 0C on improvement of the germination parameters in the laboratory (germination percentage, seedling length, fresh and dry weight and vigor index) of onion seeds cv. “Red Beheri” stored for one or two years and enhancing growth characters (bulblet diameter, transplant length, fresh and dry weights and vigor index) of the subsequent transplants. The obtained results clearly indicated that all germination parameters of onion seeds stored for one or two years (except mean germination time) and also all obtained transplant characters except leaves number were significantly increased in all moist-chilling treatments than control one. The best treatment in this regard was moist-chilling for 15 days whereas the lowest one was control (non chilled seeds).

This investigation was carried out at ،Kaffr Al-Hmam Experimental Station Sharkia Governorate during 2010/2011 and 2011/2012 to evaluate the performance of seasons eight wheat genotypes namley Sakha 93, Sakha 94, Sids1, Gemmeza 7, Gemmeza 9, Gemmeza 10, Sids10 and Giza 168. The treatments were arranged in randomized complete blocks design with three replications, in order to investigate the relationship between seed yield / plant and its factors using multivariate techniques namley; correlation, stepwise, multiple liner regression ; path –coefficient and factor analysis.
Data showed that cultivar Sakha94 recorded the highest seed / plant, and number of spikes / plant. Moreover cultivar Giza 168 recrded the lowest grain yield plant. Factor analysis grouped the studied variables in two major factors which altogether accounted for 81.00 of the total variation. The first factor include number of spike / plant, number of grains /spike, spike grain weight, and 1000-grain weight. The second factor included the remeaining variables. Multiple linear regression, stepwise and path analysis agreed upon the number of spike / plant, number of grains /spike, spike grain weight, 1000-grain weight as major contribution to seed yield variations. Factor analysis technique was more efficient than other techniques. It provides more information about cluster of intercorrelated variables. Results indicated no significant between the full model regression and stepwise for coefficient determination (R2) and standard error of stimated value, however, the efficiency expressed is due, in fact, to the reduction in variables number in the equation from all raniables in full model regression to four variables in stepwise.

Nine potato cultivars (genotypes) were grown under three different locations, Alexandria governorate, Egypt during the summer seasons of 2011and 2012 to determine some genetically parameters affecting potato breeding programs. Phenotypic (p) and genotypic (g) variability and their respective coefficient of variations, genetic advance, and broad-sense heritability, correlation coefficients among all pairs of some important potato characters along with direct and indirect effects of some traits on potato yield trait were studied .The obtained results showed that all the morphological, yield and yield component characters showed highly affecting with the genotype by environment interaction (G X E). The genotypic and phenotypic coefficients of variations had nearly equal values for the characters tuber dry matter, tuber specific gravity and tuber shape index. This result appeared that these traits were not seriously affected by the changes in the environmental factors, indicating a highly significant effect of genotype on phenotypic expression and thus would reflect positive effects for selection during the cycles of the breeding program. The characters plant length (cm), total yield (ton/fed.), No. of tubers/plant, marketable yield (%) and reducing sugars (%) possessed moderate heritability values. Accordingly, it might be stated that phenotypic selection for these characters would be reasonably effective. High heritability value along with high genetic advance as per cent of the mean was obtained for average tuber weight (gm) and tuber shape index traits. Hence, selection for the previous characters would prove quite effective since the characters seemed to be governed by additive genes action. Tuber yield (ton/fed.) showed highly positive correlation with each of the characters plant length (cm), foliage fresh weight (gm), No. of tubers/plant, average tuber weight (gm) and marketable yield (%). No. of tubers/plant and average tuber weight traits showed positive direct effects on the total tubers yield per feddan. Plant length (cm) and marketable yield (%) characters have indirect positive effects on total tuber yield per feddan through its positive relations with both No. of tubers per plant and average tuber weight (gm).

A nutritional experiments were carried out on Peppermint plants (Mentha piperita L.) at the experimental Baramoon Research Farm, Dakahlya Governorate, Egypt, during the two successive seasons, 2010-2011 and 2011-2012, aiming to investigate the effect of (FYM), humic acid, microbein and phosphorein, as well as active dry yeast on vegetative growth, herb yield, essential oil production and chemical composition of plants.
The results showed that in both seasons, all fertilizer treatments achieved significantly better growth and yield than the untreated plants (control). Treatments included that plant biomass responded linearly to (FYM) application and most values of all measurements were realized at the rate of 30 m3/fed. than obtained at both 20, 10 m3/fed. in comparison with those of control plants in both seasons, respectively. Also, it is evident that the application of (FYM) at rates of 10, 20 and 30 m3/fed., interacted with combinations of both (phosphorein + microbein), (phosphorein + yeast) and (phosphorein + humic acid) improved significant increments in the all growth characters compared with control plants, and the highest one was realized with combination of (FYM) at rate 30 m3/fed. + phosphorein + humic acid.
These findings clearly indicate that phosphorein, humic acid and 30 m3/fed. of (FYM) could be used as traditional fertilizers and may consequently minimized pollution of agricultural environments.

Alkaloids, flavonoids, triterpenes, sterols and saponins were qualitatively screened in different organs of five monocotyledonous species belonging to different genera: Allium cepaL., Asparagus densiflorus (Kunth) Jessop, Pancratium tortuosum Herbert., Kniphofia nubigena Mildr., and Urginea maritima (L.) Baker. Phenolic compounds were separated using thin layer chromatography to ascertain their relative phylogenetic position. Data collected from the qualitative phytochemical analysis, paired affinity, group affinity and isolation value reflected taxonomically significant information supported the inclusion of these species in different families by many taxonomists in the most recent classification systems.

Quantitative analyses of proximate and phytochemical contents of Allium cepaL., Aloe sinkatana Reynolds, Asparagus densiflorus (Kunth) Jessop, Pancratium tortuosum Herbert. , Kniphofia nubigena Mildr., and Urginea maritima (L.) Baker were carried out thus determining the moisture content, carbohydrates, proteins, lipid content, crude fibres, ash content, total pectic substances, tannins and anthocyanins. Data were subjected to statistical cluster analysis. The dendrogram which resulted from this analysis showed that the six species are grouped into four clusters: Allium cepa, Urginea maritima and Pancratium tortuosum are the most similar and joined to form the first cluster, followed by Aloe sinkatana, Kniphofia nubigena and Asparagus densiflorus which are sequentially added to the first cluster according to their similarity level indicated by the distance of the clusters. Compared to the recent classification systems, this dendrogram agrees only with the classification at the order level.

Two field experiments were carried out during the winter seasons of 2008/09 and 2009/10 at farm in Disuq district, Kafr El-Sheikh Governorate to investigate the response of pea plants, cv. Master B, to inoculation with biofertilizer (Halex-2) and different concentrations with boron (0, 5, 10 and 15 ppm) as a foliar application. The results indicated that inoculation of pea seeds with biofertilizer (Halex-2), improved most vegetative characters, as well as green pods yield and its components, shelling ratio, seed yield and its components, seed germination percentage, leaf contents of chlorophyll and seed content of protein. Increasing boron concentration up to 10ppm was accompanied with significant increases in vegetative growth characters, as well as green pods yield and its components, shelling ratio, seed yield and its components, seed germination percentage, leaf contents of chlorophyll and seed content of protein. The highest boron concentration at 10ppm combined with Halex-2 biofertilizer appeared to be the most efficient treatment for more vigorous growth, green pods yield and its components, shelling ratio, seed yield and its components and seed germination percentage, as well as chlorophyll contents in leaves and protein content in seeds.

The present study was conducted at the Experimental Farm of Ismailia Agric. Res. Station during 2010 and 2011 summer seasons to estimate general and specific combining ability, heterosis, types of gene action for yield and its components, pod rot diseases and perharvest aflatoxin contamination in peanut. In the first season, five genotypes differed in their economic characters and tolerance to diseases were crossed in a diallel crosses(without reciprocal). In the second season, the five parents i.e { P1(line 85),P2( line 367), P3(line 284), P4(line 205) and P5(Giza 6)} and their ten crosses were field evaluated under artificial infection with fungi inocula i.e. Rhizoctonia solani the causal of dry brown lesion; Fusarium moniliforme the causal of pink discolorationas well as Macrophomina phaseolina and Sclerotium rolfsii the main causal pathogens of general breakdown pod rot, as well as aflatoxigenic fungi i.e. Aspergillus flavus and A. parasiticus in a randomized complete block design with three replications.
The most important results could be summarized as follows:
- F1 mean values exceeded that of parents for all studied characters except plant height, number of branches and number of pods/plant.
- Specific combining ability had greater role than general combining ability for all the traits except 100-pod weight, 100-seed weight, shelling % and pod yield /fed.
- The first parent (line 85) was the best regarding general combining ability for 100-pod weight and 100-seed weight. The second parent (line 367) showed good general combining ability for most studied characters, the fifth parent ( Giza 6) had good general combining ability for the traits of 100-seed weight, shelling percentage, pod yield /fed and oil percentage.
- The crosses (P1 x P2) and (P3 x P4) were superior in number of pods/plant, pod weight/plant, number of seeds/plant, seed weight/plant, shelling percentage and oil percentage, whereas, the crosses (P1 x P5 and P2 x P4) were superior in 100-pod weight and 100-seed weight, and the hybrid (P1xP4) was excellent in 100- pod weight and oil percentage . Positive and highly significant hetrotic effects relative to the better parent were found for most of the traits in the four crosses (P1xP2), (P1xP4 ),(P2xP4) and (P3xP4). Results indicated the importance of gene action due to dominance and additive effects for most characters.
-The value of heritability was moderate to low in narrow sense but it was high in broad sense.
- Parents and F1 differed in their sensitivity to pod rots under artificial infection in the field and their contamination with aflatoxin.
-Crosses (P 1 x P 5) ,(P 2 x P 3) and Parental line 284 had the greatest resistance to all groups of pod rots followed by (P3 x P4) , (P1 x P4), (P1 x P3) and (P 2 x P 4).
- Parental line 284 and crosses (P1 x P 3) , (P1 x P5),(P 2 x P3) and (P3 x P4) were free of aflatoxin contamination ( B1, B2, G1, G2).
Therefore, the superior of crosses (P1 x P3) , (P1 x P5) and (P3 x P4 ) in yield and its components, resistance to pod rot diseases and free of aflatoxin contamination, will be further evaluated in advanced experiments to develop new genotypes that have higher yield, disease resistance and free from aflatoxin contamination.

A half diallel cross among 5 inbred lines of maize was evaluated under two different nitrogen rates for flowering and vegetative characters i.e. anthesis date, silking date, Anthesis-Silking Interval (ASI), plant height, ear height, ear leaf area and stem diameter, to evaluate the role of GCA and SCA of inbred lines in hybrids performance under high and low of nitrogen levels, and to establish the magnitude of heterosis as well as both GCA and SCA effects and their interaction with the nitrogen fertilization rates. Mean squares were significant for all studied traits except, ear leaf area under normal nitrogen level. General and specific combining ability (GCA and SCA) mean squares were significant for all studied traits, except stem diameter under normal nitrogen level at GCA and ear leaf area under normal nitrogen level at GCA and SCA. GCA/SCA ratios revealed that the non-additive gene action for anthesis date, silking date, plant height under normal nitrogen, ASI, ear height, stem diameter under both nitrogen levels and ear leaf area under stress nitrogen level. While, the additive gene action was recorded for anthesis date, silking date and plant height under stress nitrogen level and ear leaf area under normal nitrogen level. The additive gene action was the most expression under normal nitrogen level. The best combiners were P2 (Inb.95) and P4 (Inb.204) inbred lines for most of studied traits under normal and stress nitrogen levels. This result indicated that these inbred lines could be considered as good combiners for improving these traits. The best crosses for anthesis and ASI date was P2 (Inb.95) X P5 (Inb.213), for silking date was P2 (Inb.95) X P3 (Inb.144), for plant height was P3 (Inb.144) X P5 (Inb.213), ear height was P1 (Inb.84) X P4 (Inb.204) and stem diameter was P4 (Inb.204) X P5 (Inb.213) under both nitrogen levels. These crosses could be selected and used in breeding programs for improving these traits. Results showed significant heterosis for all studied traits. The best crosses over both their mid-parents and better-parents for anthesis date and silking date was P2 (Inb.95) X P3 (Inb.144) under both nitrogen levels for ASI date was P2 (Inb.95) X P5 (Inb.213), for ear height was P1 (Inb.84) X P4 (Inb.204), for plant height was P3 (Inb.144) X P5 (Inb.213), for ear leaf area was P1 (Inb.84) X P3 (Inb.144) under stress nitrogen level and for stem diameter were P2 (Inb.95) X P5 (Inb.213), P3 (Inb.144) X P5 (Inb.213) and P4 (Inb.204) X P5 (Inb.213).
