Abstract
This research aimed to estimate the genotype-environment interaction and select stable genotypes using a combination of AMMII and BLUP methods. In this study, 14 lentil genotypes along with two check cultivars, Sepehr and Gachsaran, were evaluated over four cropping years (2016-2020) in a randomized complete blocks design with three replications at the Sarab Chengai Agricultural Research Station in Khorramabad, Iran. The combined analysis results showed that genotype and environment main effects, and the genotype-environment interaction were significant. Using a combination of AMMII and BLUP methods, the stability of the genotypes was assessed. The first and second principal components cumulatively accounted for approximately 87.8% of the variances in the genotype-environment interaction. The likelihood ratio test (LRT) confirmed the significance of the genotype-environment interaction. According to the best linear unbiased predictions (BLUP) method, the WAASB and WAASBY indices, and nominal grain yield against the scores of the first axis of the principal environmental component of interaction (IPCA1), genotypes G5, G11, and G4 were identified as stable genotypes with high yield. Based on the results of this research, genotypes (FLIP2014-032L) G5, (FLIP2014-103L) G11, and (FLIP2014-021L) G4, with average grain yields of 1574.68, 1484.74, and 1452.54 kg ha⁻¹ respectively, were introduced as stable genotypes and are recommended for cultivation in environments similar to the studied climate.
