Abstract

In order to study the effects of end season drought stress on YIELD, YIELD components and some morphological characteristics of 7 varieties and promising lines and assessment based on drought indices, two separate experiments in randomized complete block design in three replications conducted in the agriculture research centre of Birjand. Drought condition made in the first experiment after anthesis and irrigation was conducted as usual in the second experiment. Varieties including Nosrat, Fajre-30 and Yousef and promising lines including MB-86-17, MB-86-10, MB-86-6 and MB-86-5 were cultured at two conditions. The results of combined analysis showed that drought stress has a significant effect on all characteristics except of number of seed per spike. Based on means comparison, highest seed YIELD with means of 8.26 ton/ha achieved from normal irrigation and lowest with means of 4.58 ton/ha achieved from drought stress condition. Also the results showed that lowest seed YIELD with mean of 5.3 ton/ha were related to Nosrat variety and highest seed YIELD with mean of 6.8 ton/ha were related to the Fajre-30 line, and there was no significant difference between these lines in context of seed YIELD. YIELD in drought stress condition has a positive and significant correlation with HARM, MP, GMP and STI indices. Also, Fajre-30 variety and MB-86-10 and MB-86-17 lines recognized as the most tolerant lines to end season drought stress based on different indices.
