بررسی خصوصیات زراعی و عملکرد دانه ژنوتیپ های گندم در آزمایش مقدماتی مقایسه عملکرد در شرایط دیم نیمه گرمسیری

Increasing in drought and heat tolerance in bread wheat genotypes will be required for the semi-tropical regions where water deficiency and high temperature are already significant limiting factors. In this research, 205 bread wheat genotypes were evaluated at Gachsaran, Gonbad, Khoramabad, Moghan and Ilam agricultural research stations in 2008-9. In preliminary yield trial ,three checks (kouhdasht, Zagros and Gahar) were planted in Randomized Complete Block Design in Gachsaran station and in the other stations they were planted in systematic arrangement after each ten new genotypes. In view of Grain Yield and optimum level of agronomic traits such as: Days to Headting, Days to Maturity, Plant Height, Agronomic Score and Thousand Kernel Weight, 38, 76, 100,73 and 37 genotypes were selected in Gachsarn. Gonbad, Khoramabad, Moghan and Ilam respectively. These lines had partially earliness and optimum thousand kernel weight and agronomic score. Based on the results of experimental data from all research stations, 34 genotypes were selected.
