بررسی صفات کمی و کیفی ارقام و لاینهای امیدبخش جو درآزمایش یکنواخت سراسری منطقه گرم

In order to determine yield stability and evaluation genotype and environment interaction 20 barley varieties and lines (along with two cheeks) were studied during cropping seasons of 80-81 and 81-82. Experiments were conducted using Randomized complet Block Design with four replications in four warm stations including Ahwaz, Gonbad, Moghan and Zabol. This study was conducted in uniformly. Simple analysis of variance and mean comparison of cultivars and lines grain yield was used for each experimental station, and also combined analysis of variance and mean comparison was used. Results showed that the effects of varieties and interaction effects between varieties and locations were not significant. On the basis of the stability analysis results, 3 cultivars and lines (5 , 13 and 15) with high stability were selected and nominated as promising lines to registered soon.
