Estimation of G x E interaction by AMMI model in some elite pigeonpea [Cajanus cajan (L.) Millspaugh] genotypes

Published on Jul 31, 2020 05:28 AM

The G x E interaction was studied in pigeonpea genotypes

using AMMI model. The results indicated that main effects

as well as G x E interaction effects were significant for

most of the traits. Major portion of the G x E was contributed

by the genotypes. AMMI model having two principle

components axis was found as the best predictive model

in this study. AMMI biplots, ASV and YSV indicated PA 620

to be the most stable genotype for seed yield and number

of secondary branches per plant during all the three years

of testing.
