Evaluation of Heterosis for Seed Yield and Its Contributing Traits in Garden Pea(Pisum SativumL.)

Abstract

Study was conducted to estimate heterosis in garden pea (Pisum sativum L.) involving fifteen parents in line x tester fashion for seed yield and its contributing traits in thirty six hybrids. Twelve parents were used as line and three as tester. The hybrids along with their parents were evaluated to assess heterosis. Among the hybrids, KS- 205 X E-6 has recorded maximum heterosis as well as good performance for seed yield with 51.67 and 48.88 percent heterosis over better parent and mid parents respectively followed by KS-216 x E-6 with 50.14 and 42.78 percent heterosis over better parent and mid parents respectively. These crosses also found to be good performer in terms of plant height, productive branches per plant, pods per plant, 100-seed weight, number of seeds per pod, 100-seed weight, pod width and pod length. High heterosis for seed yield demonstrates the presence of commercially exploitable magnitude of heterosis which can bring the quantum jump in productivity of Garden pea.
