Abstract:

Combining ability and heterosis studies for yield and quality traits in pea were conducted at Lovely Professional University Phagwara, Punjab. Ten genotype including of half-diallel fashion during winter 2016 and forty-five hybrids along with Ten parents were evaluated in 2017. Significant means squares due to line, hybrids, half diallel, parents Vs hybrids observed for yield its contributing traits. The SCA/GCA variance ratio were less than unity for day taken to 75% flowering, plant length, seeds per pod, pod density, yield per plant,100-seed weight, indicating predominance of additive gene effects for these character, therefore, it is suggested that selection in F1 generation may be either following progeny or simple recurrent selection. Among male VRPE-32, Rachana, KSP-2, PB-01, Jyoti, were observed to be the best general combiner for yield and quality traits.ie. Pod per plant, day to maturity, yield per plant. Some crosses were observed superior for the SCA effects as well as for heterosis which includes Pearpolo-5*Jyoti for primary branches, AP-3*KSP-2 for pod density, PB-01*KSP-2 for plant height. These observed can be further utilized to develop and enhance the yield potential of pea cultivars and breeding programme.
