بررسی و انتخاب نسلهای درحال تفکیک گندم نان و ارزیابی لاینهای خالص در شرایط تنشهای محیطی

‭In this study ,wheat segrigating populations (141 F2 ,26 F3 ,52 F4) and 168F5, F6 generations, using Modified Bul\ Method were evaluaed.In totaIly,93F2,25 F3 ,25 F4 and 66 , plants of F5 generation were seected,to piticipate in next generations and 44 pured lines where selected for Preliminary wheat yield trials experiments(pRWYT-zabol) in zahak exprimental station next year.In 50 pure lines had study 12 pured lines where selected for Preliminary wheat yield trials experiment (pRWYT-S) in south exprimental stations next year, SOMe significant traits, such as: resistance to diseaes and loding non‬ص ‭shattering,tillering,plant height and type,early maturity and seed health were selection criteria.
