Abstract

Stability parameters along with per plant performance of 21 genotypes of pigeonpea were
worked out for seven yield traits under three different environmental conditions. High significant
differences among genotypes were observed for all the characters except primary branches per
plant and number of pods per plant. The significant G x E for all the characters were recorded
except for days to 50% flowering, days to maturity, primary branches per plant and pods per
plant. Environment (linear) interaction component was significant for all the traits except test
weight. The variance due to pooled deviation (non- linear) was highly significant for all the
characters except for seed yield which reflect considerable genetic diversity in the material. The
genotypes ICPL 2711, ICPL 7066 and ICPL 7613 were stable under favorable conditions for
seed yield per plant.
