Mourad
A half diallel set including diverse five parental peanut genotypes was evaluated at Ismailia Agricultural Research Station, ARC,Ismailia Governorate,Egypt using randomized complete block design with three replications to estimate mean performance,combining ability,heterosis and nature of gene action.Highly significant genotypes and its components of parents,crosses and parents vs.crosses mean squares were detected for all studied traits.Highly significance of general and specific combining ability was observed for all studied traits.Additive gene action governed in plant height, number of pods/plant, number of seeds/plant,100-pod weight and shelling %. Ismalia 2,Line 360 and Giza 6 seemed to be the best combiners for pod yield /feddan and most of its components.The best cross combinations were detected in F1 crosses, P2 ×P3 for seed weight /plant and P3 × P5 and P4 × P5 for pod yield / feddan.Significant or highly significant values and high values of the dominance component (H1) were also observed for the most studied traits. P5 carried the most dominant genes responsible for the expression of seed weight/plant and pod yield / feddan, while, P4 for seed weight / plant and P1 and P2 for pod yield / feddan possessed high concentration of recessive genes. It could be concluded that, Ismalia2, Line 360 and Giza6 could be used as donors parents to improve yield and its components of peanut in the breeding program,also, the crosses P2 ×P3 , P3 × P5 and P4 × P5 with high SCA may be exploited for the development of hybrids as they had high per se performance.

In 2015/2016 and 2017/2018 Two experiments were carried out at Sakha Agricultural Research Station, to investigate the response of wheat crop to nitrogen fertilization levels(0, 25, 50 and 75 kg N/fed)on growth, chemical composition and productivity of six wheat genotypes(Misr 1, Sakha 95, Giza 171, Shandaweel 1, Misr 2 and promising line developed from Sakha breeding program(SPL2015).This research conducted using the split-plot design with four replications. In which, the main-plots and sub-plots assigned to levels of nitrogen fertilization and wheat genotypes, respectively. Results showed that high levels of nitrogen levels(75 kg N/fed)gave the highest values of crop growth rate, flag leaf area, photosynthetic pigments and Nitrogen percentage in grains. Moreover, increasing nitrogen fertilizer increased yield and its components significantly. Sakha 95 cultivar produced the highest values of all studied characteristics in both growing seasons. Meanwhile, the cultivar Misr 2 showed the highest number of spikelets/spike, additionally recorded the second best results after Sakha 95.On the other hand, Shandaweel 1 cultivar gave the longest spikes; Giza 171 cultivar recorded the highest values of 1000-grain weight,Misr1 gave the highest N% content for the grain. However, Sakha 95 under 50 kg N/fed ranked secondly in most treatments without significant differences between Sakha 95 under 75 kg N level /fed for both seasons. It can be concluded that Sakha 95 had the highest nitrogen use efficiency and this reflecting in reduction of production costs and environmental pollution by saving 25 kg N/fed under such environmental conditions of Sakha district, Kafr El-Sheikh Governorate, Egypt.

Two field experiments were carried out of the vegetable private farm at Kafr Meet Faris, Dakahlia Governorate, during 2017/2018 and 2018/2019 seasons to study the influence of planting dates (20 September, 5 October, 20 October and 5 November) either single and/or in combination with some NK-rates (100%, 110% and 120% from recommended rate) on plant growth, yield and its components, as well as chemical constituents and storability of bulbs on garlic Sids-40 cultivar. Results showed that, the Germination percentage and vegetative growth characteristics (plant height, number of leaves, plant dry weight and bulbing ratio) were better with the second planting date (5 October) followed by the third planting date (20 October) in both seasons. Moreover, total yield, bulb weight and diameter and average clove weight were increased with these planting dates. Whereas, the late planting date (5 November) gave the lowest values in both seasons. On the other hand, application of 120% NK-rate resulted in significant increases in most parameters compared with other treatments. Moreover, concentration N, P, K, TSS and volatile oils in cloves were significantly increased with this treatment. Also, this treatment was significantly reduced the weight loss percentages. The positive interactions between planting dates and NK-rates were often observed. The best results were obtained by the second planting date followed by the third planting date without significant differences between them in most cases combined with 120% NK-rate. Therefore, this treatment could be recommended for improving productivity, quality and storability of garlic under similar conditions to this work.

Estimation of Genetic Variance in Yellow Synthetic Maize "Moshtohor 108" with Reference to Expected Gain from Different Selection Methods
Ahmed
El Hosary
The field work dealing with this study was conducted during successive seasons of 2019 and 2020 in order to improve synthetic variety "Moshtohor 108". Hybridization were made between 36 male and 4 different females to made design-I as outlined by Comstock and Robinson (1948) to produce 144 full-sib families in the first season. In 2020, 144 crosses were randomly divided into 4 sets and assigned at randomized complete block design with 3 replicates. The data were taken on maturity date, grain yield plant-1 and its components. Additive (s2A), dominance (s2D) variances, heritability and expected gain from various methods of selection were estimated within the synthetic "Moshtohor 108". Males/set and females/male/set mean squares were significant for all studied traits. s2D was significant and great than s2A for most studied characters. High heritability in broad sense for all studied traits were detected and ranged from 85.83 to 79.79 along with low or moderate narrow sense were detected for all traits except 100-kerenl weight. Predicted genetic advance per cycle for improvement of "Moshtohor 108" were calculated for six methods of selection. High ∆ g % for grain yield plant-1 were achieved by using methods of test cross, half-sib with selfed seed selection and S2 fill-sib selection and ∆ g % reached 13.87, 8.4 and 8.27%, respectively. From this study, it is possible to improve the variety under study, since large variance within it and presence of additive variation with a medium degree. Thus the yield potential of this variety can be improved.

Six wheat varieties were single crossed at 2017/18. Six parents and its 15 F1 single-crosses were cultivated under N-normal and N-stress at 2018/19, to study heterosis and the genetic parameters for yield and its components under normal and N-stress. Mean squares of wheat-gentypes, parent, F1-crosses and parent versus cross were highly significant or significant for most of traits under both conditions. The highest desirable heterosis and heterobeltiosis were detected by crosses No. 7 and No.8 for earliness; No.14, No.8 and No.3 for 100-Grain weight; crosses No.8 and No.13 for number of spikelets/spike; crosses No.9, No.7 and No.13 for number of grains per spike; cross No.4 for number of spikes/plant; crosses No.3, No.12 and No.10 for grain yield per plant, therefore, it might be decided that these crosses may be beneficial for enhancing wheat grain-yield programs under low or high N conditions. The median grade of dominance was greater than one for all characters under both conditions, suggesting the importance of over dominance gene effects in the genetics of these traits. Heritability in broad sense (hb.s.) had high values for all traits under both conditions. Lower heritability estimates in narrow sense (h2n.s.) were detected for all the studied traits under both conditions, except each of spikes number /plant, weight of 100-grain and protein % at both conditions which had moderate values of narrow sense heritability, reflecting the part of environmental factors and dominance genes in heirloom scheme of these characters.

Commercial cucurbits such as cucumber, melon and watermelon are commonly grafted onto interspecific Cucurbita hybrid rootstocks to increase yield and mange soil-borne diseases. This study conducted in private farm in Qallien district in Kafr El-Sheikh Governorate northern Egypt during the period from 2018 to 2020 to identify local Fusarium wilt-resistant interspecific Cucurbita hybrid rootstocks which provide high grafting compatibility with hybrid cucumber scions. Results revealed that disease severity percentage in all interspecific hybrids (0 to 45%) was significantly lower than susceptible commercial cucumber Junco F1 (73.4%). Seven out of the 20 individual hybrids (A02, B02, D02, F01, G02, H01 and I02) were resistant or highly resistant to Fusarium wilt with a mean disease severity ≤ 25%. Results from the greenhouse trials confirmed high levels of resistance in three interspecific hybrids (G02, H01 and I02) which were used as rootstocks for cucumber Junco F1. Fruit yield parameters were increased significantly in grafted cucumber Junco F1 onto wilt-resistant interspecific hybrids compared to un-grafted cucumber. Highly significant differences in anatomical structure were observed between wilt-resistant interspecific hybrid rootstock H01 and susceptible check Junco F1. Fruit yield parameters of grafted cucumber Junco F1 were negatively correlated with disease severity. The interspecific hybrids evaluated in the present study could be promising rootstocks to increase productivity and manage soil-borne diseases for commercial production of major cucurbits in Egypt.

The experiment was carried out in two consecutive seasons (2017/18 and 2018/19) on ‘Sukkary’ and ‘Gahrawy’ mango root-stocks seedlings and the purpose of the research was to investigate the effectiveness of applying Nano-silica to increase the tolerance of ‘Gahrawy’ and ‘Sukkary’ mango rootstocks. The tested treatments were tap water irrigation (TWI),TWI and spraying Nano silicon (SNSi) at 1.0g/L,Sea water irrigation (SWI) at 1750ppm, SWI at 1750ppm and SNSi, SWI at 3500ppm, and SWI at 3500ppm and SNSi. Foliar sprays of Nano-silicon were done four times;the first at the beginning of the experiment, and then three times at 45-days intervals.The effect of treatments on the behavior of the seedlings of the two rootstocks including vegetative characteristics (new leaf area, seedling height increase%, seedling stem diameter increase, root length and width, number of lateral and secondary roots and root growth coefficient), physiological parameter "Leaf pigments, total phenols and soluble carbohydrates contents",leaf mineral contents " N, P, K, Na, Ca and Mg" and Non-enzymatic antioxidants"proline content and DPPH” as well as salinity symptoms parameters were studied. Increasing levels of salinity caused a decrease in most parameters and an increase in the sodium and proline content, and salinity symptoms of the leaves. Irrigation with salty water at 1750ppm together with foliar spraying Nano-silicon enhanced leaf content of pigments, soluble carbohydrate and total phenols, Mg, N, P, K and decreasing of salinity symptoms parameters.The results confirmed that the effects of Nano-silicon on the behavior of treated seedlings differ according to the variety under salinity conditions.

In line with sustainable agriculture that depends on modern methods and new sources of non-traditional irrigation, a field experiment was conducted at a privet farm behind Cairo-Alexandria Desert Road, Giza, Egypt during two seasons to evaluate five sugar beet varieties under water salinity stress condition. The present work included 15 treatments; represent five sugar beet varieties: viz. Multi-germs (Amina, Farida, and Faten) and Mono-germs (Unners and Sharleston), in combinations with two salinity treatments (Magic-Sal (13% humic acid + 20% carboxylic acid) and Sal-Wax (50% carboxylic acid) components) compared to control application. Results indicated that salinity treatments help in early stages to increase the emergency percentage of sugar beet varieties under high salinity water stress. As compared to control treatment, salinity treatments significantly increase proline accumulation, leaf relative water content (LRWC %),and root yield, but, it caused a reduction in quality parameters (sucrose, purity, and extractable sugar percentages) in both seasons. On the other hand, variety (Amina) overpassed the other varieties under salinity water stress with respect to germination ratio, proline content, LRWC%,and root yield (ton/fed) in both seasons. While, Sharelston variety surpassed significantly the other studied varieties with respect to sucrose, purity, and extractable sugar percentage (ES%) in both seasons.The distribution of stomata density of leaf increased as salinity water stress level increased. Results also showed that five sugar beet varieties under two salinity treatments (Magic-Sal or Sal-Wax) had positive effects and increased stomata area, but stomata density and its index as well as stomata closure% decreased compared with non-use.

Water stress is a serious abiotic stress that causes extreme loss of rice yield. Keeping these in view, fifteen hybrids along with their eight parents were evaluated at the experimental farm of Rice Research Department, Sakha, Kafr El-Sheikh, Egypt, during the two rice-growing seasons of 2019 and 2020. The analysis of variance revealed significant differences among the genotypes, crosses, lines, and lines x testers interaction for all the studied traits. Sakha 107 was identified as the potential genotype for improving grain yield under water stress based on mean value and GCA effect. While, Sakha 108 was identified as a good general combiner for improving grain yield and its related traits under irrigated condition. The significant yield reduction was observed under water stress in the majority of the rice genotypes studied. The cross combinations Sakha 107/ APO, Sakha 107/ WAB 96-1-1, Sakha 104/ WAB 96-1-1 and Sakha 101/ APO exhibited significantly low drought susceptibility index (DSI) and high yield stability index (YSI) values based on preliminary screening, and good specific combinations for certain physiological and biochemical traits, were established as genotypes tolerant to water stress. RM260, RM279 and RM514 showed the highest degree of polymorphism in the selected rice genotypes for SSR-based genotyping. Among the studied genotypes tested, the parental lines Sakha 107, IRRI 148, WAB 96-1-1 and APO were found to be more diverse based on their genetic distance. It could be considered and used for marker-assisted breeding programs as a possible water stress tolerant donor.

Two field trials were carried out at Tamiya Agricultural Research Station, (latitude of 29.58°N and longitude of 30.96°E), Fayoum Governorate,Egypt, during 2018/2019 and 2019/2020 seasons to study the relative importance of nitrogen-fixing bacteria i.e. Bacillus polymyxa (BC)and Azospirillum brasilense(AZS) as a soil drench under mineral nitrogen fertilizer levels and their effects on some sugar beet varieties. A split-plot design was used. Four treatments of nitrogen fertilization (80 kg N/fed ”control”, 60 kg N/fed + soil drench with BC, 60 kg N/fed + soil drench with AZS and 60 kg N/fed + soil drench with a mixture of BC and AZS) were occupied the main plots, whereas, six varieties (Beta303, Sirona, Panther,Des9003, Athospoly and Maximus) were distributed randomly in the sub-plots. Adding 60 kg N/fed + soil drench with a mixture of AZS and BC was adequate to produce the economical values of extractable sugar%, root and sugar yields/fed. Varieties Sirona and Maximus had the highest values of root and sugar yields/fed. Significant interactions effects among nitrogen treatments and varieties on the studied traits were discussed. Root and sugar yields/fed were significantly and positively correlated with leaf area index and crop growth rate, root diameter and its fresh weight/plant, in both seasons. Under the environmental conditions of this study, it was found that sowing Sirona and/or Maximus varieties under fertilization of 60 kg N/fed in combination with a mixture of BC and AZS at 5L/fed twice as a soil drench could be recommended to achieve the economical root and sugar yields/fed.

The effects of the treatment of irrigation at different intervals (every 3, 6 and 9 days) in interacted with foliar application treatments (tap water as control, potassium silicate at 1 and 2 % as well as salicylic acid at 25 and 50 ppm) on growth, root parameters and some chemical constituents of Dieffenbachia pictawere investigated. The current search was carried out at Horticulture Research Station at Mansoura, Dakahlia Governorate, Egypt, for two summer consecutive seasons of 2019 and 2020. Attained results referred to that irrigated dieffenbachia plants every six days significantly increased plant height, leaf length, leaf width and leaf number per plant at both seasons after three and six months from repotting date compared to the other irrigated intervals under study. Furthermore, the highest values of average of leaf area, root length, dry roots weight per plant as well as total chlorophyll, carotenoids and proline contents were obtained by the treatment of irrigation every 6 days. In addition, the highest values of above-mentioned parameters were recorded by foliar spray of potassium silicate at 2 % concentration compared with the other concentration of both potassium silicate and salicylic acid under study. In any case, the better growth and root parameters, higher chemical constituents (total chlorophyll, carotenoids and proline) could be obtained by spraying potassium silicate at 2% concentration on irrigated dieffenbachia plants every six days.

A field experiment was conducted at the Experimental Farm of Sakha Research Station, Kafr El-Sheikh Governorate, Agricultural Research Center, Egypt during 2017/2018 and 2018/2019 seasons to study the effect of mineral, bio-nitrogen fertilization and their combinations i.e. 45 kg N/fed, Nitroben and Nitrobein plus 30 kg N/fed on the straw and seed yields as well as their components of three flax varieties i.e. Sakha 5, Sakha 6 and Giza 11. A split plot design with four replicates was used. Results showed that varieties, fertilization treatments and their interaction, significantly affected straw and seed yields as well as their components in both seasons. Giza 11 variety was superior in straw and seed yields as well as their components over other varieties. Dual application of mineral N with N bio-fertilizer (Nitrobein plus 30 kg N/fed) produced the highest values of straw and seed yields as well as their components. The highest values of all traits were obtained from planting Giza 11 variety fertilized with dual application of mineral N and N bio-fertilizer (Nitrobein plus 30 kg N/fed). Hence, dual application of 30 kg N/fed with N bio-fertilizers could be recommended for improving flax varieties production especially Giza 11 variety under Kafr El-Sheikh Governorate conditions, Egypt.
