بررسی اصلاح گندم به منظور افزایش عملکرد دانه و مقاومت به تنش خشکی در اقلیم گرمسیر و نیمه گرمسیر دیم کشور

High production of durum wheat requiring high productive and environment tolerant genotypes estimation of adaptability and stability for durum wheat genotypes provide optimum criteria's for identification and extension of improved durum wheat genotypes. In this trial 20 genotypes was studied to identiiy the genotype with the highest yield and stability among 20 were evaluated in Khorramabad dry land condition. This study was conducted through a RCBD with 4 replications for Three years (2006 2009). During the growing period data were recorded from some important agronomic traits such as DHE , DMA , PLH and reaction to major diseases. Simple and combined analysis of variance performed for khorramabad grain yield data. Respectively. The results showed significant differences for genotypes ,years and genotypeا year. The results of Rank Method and Coefficients of Variation (C.V) showed that No. 1 (Bigost-1) had highest of grain yield (3775Kg/ha) and grain yield stability parameter, and selected as a advanced line for khorramabad.
