بررسی خصوصیات زراعی و عملکرد دانه ژنوتیپ های زمستانه و بینابین گندم نان در آزمایشات مشاهده ای و مقایسه عملکرد بین المللی در شرایط دیم سرد و معتدل سرد

Evaluation of genotypes in international nurseries is one of the important methods of crop improvement. This research was conducted during 2008-09 to evaluate bread wheat lines in two experiment received from CIMMYT in Turley including 16th FAWWON-SA with 65 lines in Maragheh and Sararood stastions, 11th IWWYT-SA with 20 lines in Maragheh. Azar-2 considered as checks in both experiments. Depending on important agronomic charactristics like early maturity, plant height and cold tolerance and resistance to plant disease like rusts and bunts 12 and 6 line best vigorous lines were selected in Maragheh and Sararood in FAWWON test. No. 16 in Maragheh and No. 36 in Sararood were the best genotype with high grain yield. 4 lines also seleted in Maragheh from IWWYT. No 4 (Bayractar) produced 1147 kg/ha grain yield 1% more than Azar2. The best selected lines will be evaluated in complimentary tests durring next year.
