Abstract

This study was carried out at a pots under supervision of Faculty of Environmental Agricultural Sciences, Arish University, North Sinai, Governorate, Egypt (31° 08¢ 40.3² N, 33° 49¢ 37.2² E), during winter season (2021/2022) to analyze the growth and yield traits of the studied genotypes, analyze the molecular variation between the genotypes and investigate the relation between the genetic variation and the physiological performance as a phenotypic parameters. The experimental design was Randomized Complete Block Design (RCBD) in split- devoted plots with three replications. Results showed that all genotypes were drought tolerant, moreover the Regeolone 3 genotype showed the strongest resistance to stress conditions by exhibiting the best vegetative readings after 6 days of drought stress to investigate the relation between the genotypes genetic distinguish and this performance against water stress Irrigation intervals were applied after 30 days from sowing until three months had passed.The genetic diversity between the studied genotypes had been extended and analyzed molecular by using SCOT and ISSR markers. And translation output (SDS-PAGE) and results revealed that significant molecular differences had been observed among the studied genotypes.
