Extended Abstract
Introduction and Objective: Improper distribution of rainfall and reduced rainfall are major factors in reducing lentil yield per unit area . Therefore, the use of genotypes adapted to adverse environmental conditions can play an important role in increasing yield in such conditions. Awareness of genotype × environment interactions helps breeds to be more accurate in evaluating genotypes and choosing the best genotypes.
Materials and Methods: This study was conducted during two years (2019-2020 and 2020-2021) in two stations in the cold dry areas of the country (Qeydar Zanjan, Maragheh). The experiment consisted of 17 advanced lentil genotypes along with three control cultivars Kimia, Bilesvar and Senna (20 genotypes in total) which was performed in a randomized complete block design with 3 replications.
Results: The results of combined analysis showed a significant difference in the level of one percent probability for environment, genotype and genotype × environment interaction. The results of combined analysis of variance showed that the environment, genotype and genotype by environment interaction effects were 79.5%, 2.25% and 18.23% of total variance, respectively The results of GGE biplot indicate the existence of 42.1% of the total changes related to the first component and 26% of the total changes related to the second component, which together explain 68.1% of the total changes. According to the obtained results, there is a high correlation between E1 and E3 environments and between E2 and E4 environments and they can be introduced as similar environments. In biplot study, genotypes 7 (FLIP2013-29L), 13 (FLIP 2012-262 L) and 11 (FLIP 2012-207L) had higher performance and stability at the same time.
Conclusion: Genotypes 13, 7 and 11 were introduced as high yielding and stable genotypes and can be used to select or recommend a variety.
