Additive main effects and multiplicative interaction analyses of yield performance in rice genotypes for general and specific adaptation to salt stress in locations in India

Abstract The aim of this study was to identify stable rice genotypes tolerant a salt stress environment and ideal mega-environments using AMMI (additive main effects multiplicative interaction) stability model analysis. A total 13 three tolerance checks were evaluated across locations (alkaline saline) for the two kharif seasons 2014 2015. Genotype CSR 36 (CHK3) found be most those tested. Genotypes CHK2 (CST 27) IR 87952-1-1-1-2-3-B (G05) stable, with above average yields. check genotype best performer in majority environments studied, followed by 27 (CHK2) which mega-environment consisting 21 year combinations. Overall, promising (IR 87952-1-1-1-2-3-B) had high mean yield could used commercial cultivation or as donor breeding programs salt-affected soils. GN13 87938-1-1-2-1-3-B) GN11 87938-1-2-2-1-3-B) showed 60–80% advantage at specific locations, showing that these soils India.
