Abstract

Understanding genotype * environment interaction structure for investigating genotypes STABILITY and adaptation is very important in plant breeding programs. Study was carried out on 18 genotypes of AGROPYRON ELONGATUM performance based on randomized complete block design with three replications during three years (2004, 2005 and 2007) at two environments, dry(stress) and irrigated environments (non-stress). The experiment was conducted at Islam Abade Gharb Research station, Kermanshah, Iran. Results of analysis of variance showed significant differences (p<0.05) between the studied genotypes. GENOTYPE × ENVIRONMENT INTERACTION was not significant but the first and second components of interaction (IPCA1 & IPCA2) were highly significant (p<0.01) and justified 59.92% and 29.38% of the G×E interaction SS, respectively. Mean comparison for forage yield revealed that the genotypes 10 and 15 had the highest (4.49 and 4.50 t ha-1, respectively) and genotypes 1 and 16 had the least (3.14 and 3.49 t ha-1, respectively) forage yields. AMMI1 model showed that genotypes 2, 3, 4, 5, 6, 7, 8, 9, 11 and 17 had the highest general STABILITY and AMMI2 model showed genotypes 3, 6, 11 and 17 had the highest specific adaptation to the STRESS environment.
