Abstract

      The current work was conducted at the agricultural research center in Al-Mattana during the seasons of 2019/2020 and 2020/2021. This work aims to evaluate 28 bread wheat genotypes (Triticum aestivum L.) of diverse origin under irrigated (six irrigations) and stressed environment, for yield and related traits. Moreover, to study the genetic analysis of the yield, its components for seven parents (P) and twenty-one F1-hybrids (F1) under the aforementioned environments. The data obtained for each character was analyzed on plot mean basis .All obtained results were subjected to the statistical analysis of the randomized complete block design. The data were analyzed to estimate general combining ability (GCA) and specific combining ability (SCA) effects. Under water stress conditions, all genotypes (P+F1) performed lower than normal conditions.under normal condition.
