Abstract:

An experiment comprising 20 different genotypes of pigeonpea was conducted during kharif 2016 in three different environments. In each environment each genotype was sown in a six row plot of four meter length in randomised block design with three replications. Observations were recorded on ten different character viz., days to 50% flowering, days to maturity, plant height (cm), number of primary branches/plant, number of secondary branches/plant, number of pod/plant, number of seed/pod, main shoot length (cm), 100 seed weight (g) and seed yield/plot (g)on five randomly plants of each genotype in each replication. Analysis of variance revealed that significant differences existed among genotypes for all the characters in all the three environments. In general, PCV estimates were higher than the corresponding GCV estimates for all the ten characters in all the three environments. High estimates of broad sense heritability along with high estimates of genetic advance as percent of mean was observed for 100 seed weight in all the three environments. Over all the environments, seed yield per plot is significantly and positively correlated to the days to 50% flowering, days to maturity and number of pods per plants. Days to maturity, number of pods per plant and number of seed per pods not only had direct effect but also positively and significantly associated with seed yield per plot in all the three environments.
