| Abstract | ||
| Eighteen genotypes of bread wheat were used in the study with two varieties ( Saber beg and Sham/6 ) planted in pots as CRD design for physiological and grain yield traits study , after exposing these plants to two duration of drought ( tillering stage and after giring spikes ) to aim forming selection indexes for physiological traits to determine which from these can depending on it to give high yield under water stress conditions also knowing the genotypes which resistant for drought through physiological labels. There were significantly differences at genetic variance analysis between intering samples in the study , at studing means of the studied traits and drought intensity coefficient of it , showed there was clearley variation between these traits for all the samples this variation was useful in comparing operation between genotypes at studing atrait like drought resistance in the wheat plant , also it showed at studing straits that the genetic , phenotypic and environmental variances were significantin all the studied traits and the genetic and environmental variances were equalls also the results showed that the genetic variance for most traits had formed most phenotypic variance which give us achance for selection . | ||
