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.
