Extended Abstract
The current research aimed to identify stable and high grain yield chickpea genotypess using the integration of AMMI and BLUP methods with WAASBY, and MTSI indices.
Material and Methods:
In this study, fifteen improved chickpea genotypes with two control genotypes )Mansour( and the local population of Bionij were evaluated in a randomized complete block design with three replications in Lorestan (Khoramabad) and Ilam (Cherdavol) during three cropping seasons (2019-2020). The simultaneous selection for grain yield and stability based on several traits was conducted using the scores obtained from an exploratory factor analysis.
Results: The mosaic diagram showed that the contribution of the sum of squares of genotype and the genotype × environment in the total sum of squares was 9.54 and 14.72%, respectively. The Likelihood Ratio Test (LRT) showed that the effect of genotype by environment interactions (GEI) was significant on grain yield, 100-seed weight, plant height, number of days to flowering, number of days to maturity, grain filling rate, grain filling period, rainfall productivity, The rate of seed yield formation, and single grain weight.Three factors with eigenvalues of greater than one explained a total of 81.2% of the total variation. MTSI index, by profiting from factor analysis and WAASBY methods, is a more efficient index in identifying superior genotypes and developing high-yielding and stable cultivars
Conclusion In general, based on the results and simultaneous selection, genotypes 2(X010TH158K2) and 8 (TRN-7 ) were stable and superior genotypes and could be recommended to the farmers.
