Studies on Combining Ability and Heterosis for Some Traits of Root and Yield Characters of Some Rice Genotypes Under Normal and Water Deficit Conditions
Abstract:Eight genotypes cultivars of rice were crossed to obtain 15 F 1 crosses, through line x tester mating design was employed for this purpose. The experiment was carried out using line x tester mating design, during 2021 and 2022 rice growing seasons at the experimental farm of Sakha Research Station, Sakha, Kafr El-Sheikh, Egypt. Both GCA and SCA variances were found to be significant or highly significant for all studied traits. The estimates of GCA effects indicated that, the parent IR 12 G 3222 was a good gen… Show more
