Yield Stability of lentil genotypes in Drland Zones, west of Iran Using AMMI Analysis

Plant breeders arc usually faced with Gill interaction in their studies on crop varieties in multilocation trials (METs). This Study was carried out to determine the yield performance and adaptability of 10 lentil genotypes at four stations of; Kurdistan, Maragheh. Zandjan and Ardebil west of Iran, during three successive growing seasons (2001-03), Theexperiments wereconducted using a randomized complete block design with four replications. Fallowing homogeneity test for error variances, combined analysis of variance was carried out. F-test for sources of variations revealed the fact that the effects of variety, year, location, variety x location, and variety x yearx location were significant. Additive main effects along with multiplicative interactions (AMMl) analysis indicated that the yield performances of genotypes were affected by the major environmental effects of genotype x environment interaction. The first two principal component axes (PCAl and 2) were significant (P
