بررسی تاثیر تنش خشکی بر عملکرد و اجزای عملکرد ژنوتیپهای گندم دوروم

In order to evaluate some morphological properties of durum wheat genotypes under both normal irrigation
and drought in the research field crops in Kermanshah University 92-91 in a randomized complete block
design, each with three replications some tests were conducted. Properties such as seed yield, seed weight,
Number per spike, biological yield, plant height, spike length and awn length were evaluated. The results of
combined analysis of variance showed that the environmental effects for all properties were significant, but
no difference has been seen for spike length. It showes that stress has a negative impact on the characters.
Genotype-environment interaction for grain yield, number of grains per spike, plant height and biological
yield was significant in different environments. Comparison between means showed that genotypes 8 and 15
had the highest yield in non-stress environments and genotypes 17 and 4 had the highest yield in stress
condition.
