Ameer
Shalan
ABSTRACT A field experiment was conducted in a randomized complete design with three doses of Nano-powder potassium sulfate(100, 150 and 200 g per vine) and one dose of traditional potassium sulfate (200 g per vine), which applied as soil applications to compare the effect of potassium at nano or traditional form on the performance of Crimson seedless grapevines during 2018 and 2019 seasons. Results revealed that the Nano-powder potassium sulfateat 150 and 200g per vine was better than the traditional form in enhancing vegetative growth, nutrient uptake, cluster quality and yield of Crimson seedless grapevines. In summary, it can be concluded that utilizing a nano form of potassium sulfate at an equal dose of traditional form or by less than fifty gram lead to an increase in the productivity of Crimson seedless grapevines.

A field experiment was carried out during the two successive early summer growing seasons of 2018 and 2019 at the Experimental Farm of El- Gemmeiza Agric. Res. Station, Gharbeya Governorate, Egypt to study the effect of foliar spray with three substances, i.e., Vitamin E (Vit.E) at 150 ppm, super Vigro –X at 1ml/L, salicylic acid (SA) at 150 ppm individually, or in combinations on plant growth, biochemical traits, pods yield and its quality of pea cv. Master B grown in clay soil. The results indicated that, spraying pea plants with Vit. E + super Vigor-X + SA three times at 20, 30 and 40 days after sowing gave the highest values of plant height , both number of leaves and branches/ plant , total dry weight/ plant , leaf chlorophyll pigments , N,P and K percentage in shoot, yield and its components and the best pod quality of pea and gave the lowest concentrations of proline amino acid and oxidase enzyme activity in shoots. Moreover, this treatment recorded increasing in total yield about 63.8 % (average two seasons) than control (unsprayed) plants Meanwhile, spraying plants with super Vigor-x +SA treatment came in the second rank in this respect.

A field experiment was carried out during the summer seasons of 2018 and 2019 at Gemmeiza Agric. Res. Station, Gharbeya Governorate, Egypt to evaluate effects of mineral and organic nitrogen as well as using vitamin C and chitosan as foliar spray on growth , yield and fruit quality of sweet pepper cv. California Wonder grown in clay soil. The interaction between fertilizing sweet pepper plant with MN at 25 % RR+ON at 75 % RR and spraying with Vit.C at 300 ppm increased plant height, number of leaves / plant, number of branches/ plant and shoot dry weight at 90 days after transplanting in both growing seasons. However, fertilizing plants with MN at 25 % RR +ON at 75 % RR and spraying with chitosan at 2ml/l or Vit.C at300 ppm increased N,P and K contents and their uptake by shoot. In addition, the interaction between fertilizing with MN at 25 % RR+ON at 75 % RR and spraying with chitosan at 2ml/l increased average fruit weight, yield / plant and total yield /fed. as well as nitrogen use efficiency and lowest values of nitrate content in fruits. Nevertheless, the interaction between fertilization with MN at 50 %RR+ ON at 50 % RR and spraying with chitosan at 2 ml/l increased DM% in fruit, whereas the interaction between fertilizing with MN at 50 %RR+ON at 50 %RR and spraying with Vit. C at 300 ppm increased TSS and Vit.C in fruits in both seasons.

Selection for Earliness in Two Wheat Populations under Toshka Conditions
S.
Nassar
Drought is a significant constraint for defecting yield and output potential as growth and productivity of plants are adversely affected by water stress which leads to heavy yield losses. A good drought tolerant wheat line should have the ability to withstand in water deficit conditions or have the ability to escape from it. The present work aimed to study the effect of two cycles of pedigree selection for earliness in two segregating populations of wheat under water stress, during 2015/16 and 2016/17 season at Toshka Station, Desert Research Center, Aswan, Egypt. The water treatments were 100 and 67% of the irrigation requirements of wheat in Toshka as normal and drought condition, respectively. The selected family No. 12 was the earlier family and recorded 55.33 and 48.33 days under normal and drought stress, respectively. Moreover, family No. 10 was the best family that showed high grain yield under both water irrigations in Pop.1. Drought stress led to reduce grain yield/plant (GYPP) by 35.3% in best family. These families could be considered as tolerant to drought stress and could be used in breeding program for drought tolerance and earliness. In Pop.2, family No. 6 was the best selected one in (GYPP, BYPP, GYPS, NGPS and 100-GW) under normal conditions, while the family No. 7 was the best one for days to heading under normal and drought stress conditions. The performance of the selected families under normal and/or drought stress conditions may determine the goals and attitudes of the selection program.

Direct and indirect selection for grain yield through 1000grain weight, spikelet fertility and spike density were achieved in bread wheat at the Exper. Farm Fac. Agric., Minia Univ. Egypt during the three successive seasons of 2016/17 to 2018/19. After two cycles of pedigree selection phenotypic variation of grain yield/plant, 1000grain weight, spikelet fertility and spike density decreased rapidly from F2 base population to F4. Indirect selection through high 1000 grain weight resulted in the highest grain yield/plant (23.62g) followed by direct selection for grain yield/plant (20.66 g). Average direct gain for the ten selected families of direct selection for grain yield showed highly significant increase in percentage of the bulk sample of 62.95% and the better parent of 39.25%. Pedigree selection was effective in detecting the high yielding families. Family No. 145 gave significant (P≤0.01) grain yield in percentage of the better parent and bulk sample by 77.09 and 107.23%, respectively. Average direct response in percentage of the bulk sample was significant and reached 21.08% for 1000 grain weight, 31.12% for spikelet fertility and 7.27% for spike density. Three families; No. 15, No. 72 and No. 153 surpassed significantly the bulk sample by 33.83, 43.01 and 29.28%, respectively, when selection practiced for 1000 grain weight. Family No. 145 considered to be a promising line in grain yield and spikelet fertility. High strong positive genotypic correlation was found between grain yield with each of weight of spikes/plant (0.81), no. of grains/spike(0.71), weight of grains/spike (0.91), 1000grain weight(0.92) and spikelet fertility(0.70).

A field experiment was carried out in Ismailia Experiment Station, ARC, Ismailia Governorate, Egypt, during 2016/2017 and 2017/2018 seasons, to study the effect of planting dates (1st, 10th and20th March) of watermelon relay intercropping with wheat and wheat cultivars (Misr 1, Gemmiza 11and Sakha 93) on productivity, land use efficiency and profitability per unit area. A split-plot design was used with three replications. Results indicated that growth, yield and its attributes of wheat were insignificant effect by watermelon planting dates. Contrary, planting dates of watermelon relay with wheat significantly affected watermelon traits. Early planting date on 1st March of watermelon had highest values of growth, yield and yield components. On the other hand, late planting date of watermelon decreased growth, yield and its components. Wheat cultivars varied significantly in all studied traits. Misr 1 cultivar had the highest grain yield/fad compared to Gemmiza 11 and Sakha 93. However, watermelon relay intercropping with wheat cultivar Sakha 93 significantly increased branches number/plant, number of fruits/plant, mean fruit weight and fruit yield/fad of watermelon. Relay intercropping watermelon with wheat Sakha 93 cultivar on 1st March had 15.41ardab/fad of grain wheat + 25.29 t/fad fruits of watermelon and increased land equivalent ratio (LER), area time equivalent ration (ATER) and total income compared to solid watermelon culture had 26.15 t/fad of fruits and 57920 L.E/fad, respectively. Therefore, this study suggested watermelon relay intercropping with wheat to share land resources and production inputs as well as increased wheat production and grower profitability in watermelon cultivated areas.

The F2 and F3 populations resulting from Giza171 × Sids12 hybrid were used from 2015/2016 to 2018/2019 seasons at Sakha Agricultural Research Station to study the inheritance of some agronomic characters and resistance to rusts diseases and select new bread wheat families with high yield potential and good grain quality. Giza171 was preferable for yield and its components, while Sids12 was desirable for earliness characters. The ranges of the F2 and F3 populations went out the means of its parents for the studied characters. All characters showed moderate to high values of broad sense heritability in F2 and F3 generations. The best responsive characters to selection in F2 were No. spikes plant-1 and grain yield plant-1, while days to maturity was the least responsive character. F3 families hadhighly significant variations for all studied characters. Correlation coefficients referred that grain filling rate, followed by No. spikes m-2, then kernels weight spike-1, later the No. kernels spike-1 had the most impact on grain yield in F3 families. The resistance of yellow and leaf rusts was controlled by two dominant genes and stem rust was controlled by two complementary dominant genes. Thirteen promising families were high yielding, resistant to the three rusts and have appropriate height were selected to promote to the next advanced of segregating generations and five of them were preferable for grain quality of wheat.

A study was accomplished in a field experiment at Sakha Agricultural Research Station Farm, to assess 18 bread wheat genotypes (16 promising lines and 2 checks) during 2014/2015 and 2015/2016 seasons over ordinary and salinity soil circumstances. Analysis of variance showed highly significant effects between genotypes and salinity soil treatments. Interaction effects were highly significant between all components of interaction except few cases. There were significant reductions in all studied characters due to salinity circumstances measure up to through normal circumstance. The obtained results showed that Lines 2, 14 and 15 and cultivar Misr 1 were the best genotypes under study. These genotypes had highest values for grain yield and its components under non-saline and/or saline soil conditions. Stress tolerance indices (STI's) results indicated that GMP and STI indexes gave similar ranks for lines 2 and 14 which can identified as salt tolerant genotypes. Lines 8 and 10 were recognized as sensitive genotypes, for reason that their little means for GMP and STI. In the similar situation, the 2 indexes TOL and SSPI ranked the considered genotypes for salt acceptance and indicated that lines 11, 14 and 2 were further tolerant to salinity stress. The correlation analysis Spearman's rank correlation coefficient between the salinity tolerant indices was used. There were highly significant positive correlation with salinity tolerant indices MP, GMP, STI, TOL and SSPI under normal condition. Whereas, at salinity (Ys) conditions correlation was highly significant and positive with salinity tolerant indices MP, HM, GMP, STI, YI and YSI.

Diallel Analysis of some Quantitative Traits in Eight Inbred Lines of Maize and Gge Biplot Analysis for Elite Hybrids
A.
El Hosary
An 8x8 half diallel analysis were performed at two planting dates to study the importance of types of combining ability (GCA and SCA) and its interaction with environment in F1 of maize. Planting dates (D), crosses (Cr), GCA, SCA, CrxD, GCAxD, SCAxD were significant for all traits. GCA/SCA exceeded the unity for most traits. Non-additive seemed to be more prevalent for plant, ear heights and grain yield plant-1. P8 gave significant positive () effects for all studied traits. High SCA effects were exhibited by the crosses P1xP7, P1xP8, P2xP5, P3xP4, P3xP8, P4xP7, P4xP8 and P5xP6 for grain yield plant-1 across planting dates. Superiority of P2xP5 and P3xP8 over SC Hytech 2031 reached 13.84 and 6.16%, respectively. However, useful heterotic effects relative to SC 128 mean value were 21.14 and 10.22%, for the aforementioned crosses, respectively. P1xP8, P4xP8 and P5xP6 gave positive insignificant out-yielded than check hybrids. The five superior hybrids P2xP5 (G1), P3xP8 (G2), P5xP6 (G3), P1xP8 (G4) and P4xP8 (G5) along with SC10 (G6), SC 128 (G7) and SC Hytech 2031(G8) were evaluated in 2019 season at various environments using RCBD with 3 replicates to identify environments and suitable adapted maize hybrids. Stable genotypes are ranked descending for means of grain yield as follows: G1 > G8> G2> G7. G1, G8, and G2 were above average stability while genotypes G7 showed below average stability. Thus, G1 (P2xP5) and G2 (P3xP8) are promising crosses, and it's recommended to register as new varieties with high productivity and stability across environments.
