Abstract:
The present experiment was carried out at Pulses and Castor Research Station, Navsari agricultural university, Navsari in Rabi 2019. Six diverse elite genotypes (NIFPGr-17-64, GDF-1, NF-18-52 (Local), NIFPVg-17-10, NIFPVg-17-12, and NIFPGr-17-64) were crossed in half diallel fashion for combining ability analysis for yield and yield attributing traits in fieldpea. NIFPVg-17-12 was found as a good general combiner for the duration of the reproductive phase, branches per plant, pods per plant, seeds per pod, and yield per plant. Whereas, for hybrids, GDF-1 × NIFPVg-17-10, GDF-1 × NIFPVg-17-12, and NIFPVg-17-12 × NIFPGr-17-63 were observed as good specific combiners. The magnitude of GCA variance is lesser than sca variance for most of the traits indicating the predominance of non-additive type of gene action.
