Abstract
Aim: The present
investigation was conducted to approximate the magnitude of genotype ?
environment interaction effects in mungbean crop and to identify suitable
genotypes for northern hilly terrain of India.
Methodology: Thirty one
promising mungbean genotypes were evaluated in three diverse environments,
viz., Srinagar, Berthin and Imphal of northern hilly terrains of India. The
individual genotype was planted in 5 rows of 4m length in 3 replications in
randomized block design. The statistical analysis was done for Additive Main
effect and Multiplicative Interaction (AMMI) and genotype main effect plus
genotype-by-environment interaction (GGE) biplots analysis.
Results: ANOVA devised
that the genotypes, environment and genotype ? environment interactions were
significant for grain yield. The first two principal components, PC1 and PC2
described 73.65 and 26.35 percent variations, respectively, of total
variation. According to AMMI I, the genotypes such as Pant M 6, RMG 1092, TMB
134, CoGG 13-19, KM 2349, DGG-8, TRCM 87-6-2-1, KM 2241 and MDGGv-16 were
highly stable genotypes. GGE biplot analysis revealed that Pant M 6 and TMB
134 as winning genotypes for Berthin while NMK 15-12 and MDGGV-16 were the
best genotypes for Srinagar. The genotypes IPM 14-7 and GAM 5 were found best
for Imphal. Overall, high yield and most stable genotype was DGG-8 for
northern hilly terrains of India.
Interpretation: GGE biplot and
AMMI approach could be instrumental in appraising the genotypes performance
in multi-environments/locations testing for efficient selection of the stable
genotypes.
Key words: AMMI plot, GGE, Mungbean, Stability
