AMMI based simultaneous selection for yield and stability of chickpea genotypes in south zone of India

Abstract

Multi-environmental trials have generally significant genotype main effects and genotype x environment interaction (GEI) effect and, therefore different univariate and multivariate stability methods have been used to study the GEI. Among the multivariate methods, the additive main effects and multiplicative interaction (AMMI) analysis is widely used for GEI investigation. This method has been effective because it captures a large portion of the GEI sum of squares; it clearly separates main and interaction effects and often provides meaningful interpretation of data to support a breeding program such as genotypic stability. Based on the AMMI model, a stability index has been used to rank the genotypes. This index is the weightage of stability and yield component and higher the index value better is the genotypes. The index of 40 promising chickpea genotypes were calculated with two different weight of yield (50% and 75%) and stability component (50% and 25%). These genotypes were evaluated at seven locations viz. Hiriyur, Nandyal, Coimbtore, Dharwad, Lam, Bijapur and Gulbarga representing the south zone of All India Coordinated Research Project on Chickpea program during 2015-16. Ranking of genotypes are done based on two different weight of stability and yield component.

Genotype-by-Environment (G × E) Interaction and Grain Yield Stability Analysis for Selected Genotypes of Desi Chickpea (Cicer arietinum L.) by using AMMI Model

“…However, there were no closely linked genotypes for the environment E4 that were readily available. All the findings ofFunga et al in the present analysis are in agreement with the findings ofKumar et al (2020) andDhuria and Babbar (2021).…”

“…The presence of G  E interaction was clearly demonstrated by the AMMI model in which five of the principal component axes (IPCA1, IPCA2, IPCA3, IPCA4 and IPCA5) were significant (Table 3). Significant G  E interaction also reported by Balapure et al (2016) and Kumar et al (2020) for grain yield by using AMMI model.…”

Evaluation of Performance and Yield Stability Analysis Based on AMMI and GGE-Biplot in Promising Pigeonpea [Cajanus cajan (L.) Millspaugh] Genotypes

“…However, shifts in rainfall patterns and seasons due to climatic change require the development of varieties that have wider adaptability. Such new varieties must show high performance for yield and other essential agronomic traits and their superiority should be consistent (stable) over a wide range of environmental conditions (Hemant kumar et al 2018).…”

“…Moreover, developing varieties with a broad range of adaptation requires the resourcedemanding approach of manipulating genetic backgrounds and screening of large germplasm accessions across different environments contrasting in biotic and abiotic factors. However, the ability of some genotypes to inherently exhibit stability over a wide range of environments is a promising indication for adaptation breeding (Ojo et al, 2006;Kumar et al, 2020). Kumar et al, (2020) successfully used AMMI model to rank 40 promising chickpea genotypes tested in seven diverse environments in India.…”

Breeding for adaptive traits is not only essential for attaining yield stability across different agro-ecological environments (Meseka et al, 2003), but will also ensure expansion of crop production into nontraditional agricultural areas.…”
