Heterosis estimates of garden pea crosses (Pisum sativum L. hortense).

Saumya Awasthi, G. R. Lavanya, Rashmi Jain

Abstract

An experiment was conducted to study heterosis in garden pea for different quantitative characters. Analysis of variance for heterosis showed significant differences among all crosses for all characters, indicating that there is ample scope for selection of promising crosses from present gene pool for yield improvement in garden pea. Cross EC 328758 x Swarnamer showed significant heterosis, heterobeltiosis and standard heterosis for pods per plant and seed yield whereas EC 269396 x Pusa Pragati exhibited negative significant heterosis and heterobeltiosis for days to maturity, indicating earliness.
