بررسی خصوصیات زراعی و عملکرد دانه ژنوتیپهای زمستانه و بینابین گندم نان در آزمایشات مقایسه عملکرد در شرایط دیم سردسیر

Evaluation of new pure lines in preliminary and advanced yields trials is one of the important process of plant breeding, This research was conducted in Maragheh dryland agricultural research station in 2006- 2007 to evaluate 80 bread wheat lines in 4 experiment with 3 replications in RCBD. Azar-2 Sardari considered as checks in every experiment.Depending on important agronomic characteristics like early maturity, plant height and cold tolerance and resistance to plant disease like rusts anf bunts totally 17 best vigorous lines were selected. However, considering earlyness and plant height, the selected lines were like as checks, But thousand kernal weight is less than checks in common. The line No. 14 in ARWYT-2 were the best genotypes with grain yield of 3385 kg/ha and 14% more than Azar2. The best selected lines will be studied for adaptability and stability analysis in uniform regional yield trials durring next years.
