Kafer El-Sheikh, Egypt during during 2013/14 and 2014/15 seasons to evaluate thirteen faba bean promising lines under early (mid- October) and late (mid- November) sowing dates comparing with three commercial cultivars. Each sowing date was conducted in a separate replicated complete blocks experiment and combined analysis was done over both sowing dates and growing seasons to study the effect of genotype x environment interaction on heritability and genetic advance for seed yield and some related traits. Highly significant mean squares of seasons were detected for all studied traits. Sowing dates and genotypes mean squares were highly significant for all traits tested. Mean squares of sowing date x season interactions were highly significant for chocolate spot reaction, No. of seeds/plant and seed yield /plant. Highly significant mean squares of the interactions between genotypes and seasons were found for chocolate spot, No. of pods and seeds/plant, 100-seed weight and seed yield /plant. The interactions between genotypes and sowing dates were highly significant for maturity date, no. of seeds/plant and seed yield/plant. The highest values of predicted genetic advance were mainly due to high vales of heritability and the latest was coupled with high phenotypic coefficient of variability.

The cantaloupe <em>Cucumis melo var cantaloupensis</em> Cv. Marella was grafted onto three rootstocks were Shintosa, Star and Cobalt. The plants were grown hydroponically in sand culture under three saline concentrations of 0, 100 and 150 mM NaCl for 30 days to investigate the effects of salinity on grafted Cantaloupe plants compared with non-grafted ones. The results proved that The results proved that grafted Cantaloupe plants had a better performance than the non-grafted ones especially grafted onto Star rootstock. Grafted plants recorded highest growth vigor as indicted by shoot and root fresh and dry biomass, shoot length, number of leaves and stem diameter compare to non-grafted plants under saline and control conditions. Mineral uptake was significantly affected by rootstocks and salinity levels. Accumulation of sodium (Na<sup>+</sup>) was reduced in grafted plants compared with non-grafted ones. Nitrogen (N), Potassium (K<sup>+</sup>) and Magnesium (Mg<sup>++</sup>) uptake by shoots of both grafted and non-grafted Cantaloupe gradually decreased with increasing NaCl salt concentration. The concentration of K<sup>+</sup>, N and Mg<sup>++</sup> were higher in grafted plant leaves than non-grafted ones. Ratios of K<sup>+</sup>/Na<sup>+</sup>, N/Na<sup>+</sup> and Mg<sup>++</sup>/Na<sup>+</sup> were affected by salt treatments and positively associated with plant growth traits. These ratios recorded higher values in grafted plants compared non-grafted ones under both saline and control conditions. It could recommended to grafting Cantaloupe to increase its tolerance to saline conditions.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36698620170601Plant Distribution Patterns and Irrtgation Intervals Effects on Yield and Quality of Sugar Beet in North Delta6796844052010.21608/jpp.2017.40520ENM.
