Abstract/Description: | In the present study, a total of 53 promising salt-tolerant genotypes were tested across 18 salt-afected diverse locations for three years. An attempt was made to identify ideal test locations and megaenvironments using GGE biplot analysis. The CSSRI sodic environment was the most discriminating location in individual years as well as over the years and could be used to screen out unstable and saltsensitive genotypes. Genotypes CSR36, CSR-2K-219, and CSR-2K-262 were found ideal across years. Overall, Genotypes CSR-2K-219, CSR-2K-262, and CSR-2K-242 were found superior and stable among all genotypes with higher mean yields. Diferent sets of genotypes emerged as winners in saline soils but not in sodic soils; however, Genotype CSR-2K-262 was the only genotype that was best under both saline and alkaline environments over the years. The lack of repeatable associations among locations and repeatable mega-environment groupings indicated the complexity of soil salinity. Hence, a multilocation and multi-year evaluation is indispensable for evaluating the test sites as well as identifying genotypes with consistently specifc and wider adaptation to particular agro-climatic zones. The genotypes identifed in the present study could be used for commercial cultivation across edaphically challenged areas for sustainable production. |
