بررسی خصوصیات زراعی و عملکرد دانه ژنوتیپهای گندم نان در آزمایشات مقایسه عملکرد در شرایط دیم نیمه گرمسیری

In order to evaluation of grain yield and some agronomic characteristics of some bread wheat advanced lines and cultivars this experiment was conducted in Moghan Agricultural Research Center in 2006-2007, planting season. This experiment was include two main experiments, first part including ARWYT and BRWYT and second one was PRWYT. In advanced yield trial we had 106 treatments ( in five experiment, four ARWYT and one BRWYT) conducted with randomize complete block design with 3 replication. PRWYT experiment conducted systematically. it had not any replication. Each plot size in both yield trial experiments were (1.2m5اm = 6.2 m2). The result of ANOVA analysis for grain yield in ARWYT2 showed significant differences and others were non significant. That mean compotation with check selected 2 best lines (number 2, 13 with 1272 and 1172 respectively). From PRWYT experiment 45 genotypes (27% genotypes) was selected.
