بررسی و انتخاب در توده ها و نسل های در حال تفکیک گندم نان برای مناطق با عرض جغرافیایی پایین مرکز و غرب آسیا و شمال آفریقا ‭(CWANA)‬

Abstract In this study' bread wheat segregating populations and generations include: 271 F2's, 2275 plots from F3, 571 plots of F4, 236 F5's and 2385 F6 lines' using modified pedigree- bulk methods were evaluated. In totally, 629 single plant of F2's, 130 plots from F3, 44 plots from F4, 347 single plant of F5 and 255 lines from F6 generation were selected to participate in next generations and preliminary yield trials (PYT) in next year. Some important traits such as: resistance to diseases and lodging, resistance to shattering, No. of tillers, plant height, early maturity and seed health were selection criteria.
