بررسی صفات مورفو-فیزیولوژیک و پایداری عملکرد دانه و شاخص برداشت در ژنوتیپ های امیدبخش گندم نان زمستانه و بینابین در اقلیم سرد‭(ERWYT-C)‬

Appearance of different traits in genotypes are under genetic and environmental controls. Interaction effect of genotype x environment ,results different reaction of genotypes in different environments, so determination of genotypes adaptability in different environments is necessary. In this study 16 winter and facultative bread wheat genotypes plus two check cultivars (totally 18 genotypes) were evaluated iI1 12 research stations in 2004/05 and 2005/06 cropping seasons. Experimental design in all stations was randomized complete block with three replications. Results of combined analysis of variance showed signiticant location x year, genotype x location and genotype x location x year interactinn effects. Based on results of stability analysis using simultaneous selection for yield and '.stability, genotype C-83-8 (130 Ll.l I/lF35.70/Mo73/4/Ymh/Tob//Mcd/3/Lira) with an average grain yield of 7550 kg ha'l was detelmined as superior genotype. In this study pre-anthesis pholoassimilate contribution ID grain (PAPCG) was detennined from 28 to 42% with an average of 36%.
