Abstract

Eleven early maturing pigeonpea genotypes were evaluated along with a national check (ICPL-
87) for their yield performance during four years (1997-2000). The experiment was laid out in
randomized block design with four replications. Significant genotypic differences for yield and
majority of the component characters were observed. Highly significant genotype-environment
interaction indicated differential response of the genotypes to the environmental changes. The
stability analysis was carried out ,which showed significance of linear component of variation for
important traits including grain yield. The genotype SKNP-9264 showed highest yield (1874 kg/
ha) with high stability (bi=1.09, S2di=0.27) followed by SKNP-9256, SKNP-9203-1, SKNP-9217
and SKNP-9226. The genotypes SKNP-9264 and SKNP-9256 were also found stable for pods/
plant, primary branches/plant, 100-seed weight, plant height and days to maturity. Similar trend
for component traits was also observed for SKNP-9203-1, SKNP-9217 and SKNP-9226. SKNP-
9260-2 was found unstable over environments for yield (bi=0.64, S2
di=1.45). The result revealed
that SKNP-9264 and SKNP-9256 can be exploited for stabilizing yield of pigeonpea in fluctuating
environments of Gujarat state.
