Improvement of Grain Quality Traits in Bread Wheat Genotypes Through Mutation Breeding Using Gamma Irradiation

This study was conducted to determine changes for some quality characters in M2, M3 and M4 mutated populations of three bread wheat genotypes irradiated by different gamma rays. The results showed that the significantly variably differed their response various traits at rays doses M3, populations. shifts per see from controls examined such as thousand-grain weight (TGW), test (TW), wet gluten content (GC), index (GI), Zeleny sedimentation value (ZSV), protein (PC) mutant were significant according t-test analysis. desired variations could be obtained generations with irradiation depending on genotypes. Although ZSV, GC, PC significant, TGW, GI, TW an unchanged or slightly negative generations. It can generally said it may more appropriate perform selection after generation seed effect mutagen varies character, genotype, mutagenesis examined, most appropriategamma-rayy are 300 200 Gy because causing controls.
