Abstract:

Ten F1 hybrids of grass pea and their 5 parents were evaluated in a randomized complete block design in three replication to assess the extent of average heterosis, heterobeltiosis and economic heterosis over standard checks i.e. Mahateora and Prateek for yield and its components. F1 were generated in Half diallel mating design. Heterosis for seed yield plant-1 was reflected through heterosis in number of branches per plant, number of pods per plant, number of seeds per pod, number of seeds per plant, plant biomass, seed density and seed index. The hybrid Prateek x Siraha Local expressed the highest average heterosis for seed yield per plant followed by Siraha Local x RLS 3004, Ratan x Siraha Local. Similarly, for heterobeltiosis, the highest value was reported by Prateek x Siraha Local followed by Siraha Local x RLS 3004 and heterosis over standard parent was manifested by only one cross Prateek x Siraha Local. Based on per se performance, heterosis and half diallel analysis, the cross combinations Prateek x Siraha Local, Siraha Local x RLS 3004 and Ratan x Siraha Local were found promosing. On the basis of yield these further can be utilized for selection of superior transgressive segregants.
