بررسی ارزیابی ارقام و لاینهای گندم نان برای تحمل به خشکی در آزمایش مقایسه عملکرد مقدماتی در اهواز ‭( PRWYT-DROUGH)‬

This study was carried out in an observation experiment with 125 bread wheat lines selected from national breeding program and international nurseries and with four checks including Chamran and Dez cutivars and S-78-11 and S-80-18 lines in 2008-09 cropping seasons. Two water treatments including well water (irrigation after 75-100 mm evaporation from Class A Pan evaporation) and drought stress (irrigation after 100- 150 mm evaporation from Class A Pan evaporation) were applied. Grain yield , some agronomic trais and response to disease were evaluated. Results indicated that the rang of grain yield was 175-7325 Kg/ha, whereas grain yield of the checks was 2600-5625 kg/ha . Eighteen superior lines including No.: 1,19,20,21,50,56,61,63,66,69,72,73,81,83,108,109,116, and121were selected for further evaluated in advanced regional wheat trial for drought condition (AWRWYT-D) in 2009-10 cropping seasons.
