Estimation of heterosis for yield and yield contributing characters in CGMS based pigeonpea [Cajanus cajan (L.) mill sp.] hybrids

Abstract

The objective of present study is to estimate the standard heterosis among parents and crosses to find out promising cross combinations for seed yield and its components. The experimental material comprised of 40 crosses along with 13 parents (5 lines and 8 testers) and a standard check BDN 716. The experiment was laid out in Randomized Block Design with two replications. The observations were recorded on eleven characters for evaluation. The analysis of variance revealed that there were significant differences among the parents and crosses for all the characters studied. The cross BDN 2004-4 A x BDNHR 35-8 had manifested significant positive standard heterosis over check BDN 16 for yield and yield contributing characters viz., seed yield per plant and number of pods per plant.
