Abstract

Heterotic effect of eight characters were studied in Generation means analysis of five pea (Pisum sativam L.) crosses. Highest values of heterosis was observed for yield per plant and number of pods per plant. The extent of heterosis was 55.14 per cent for grain yield per plant and 49.92 per cent for pods per plant. Cross which showed manifestation of high degree of heterosis also exhibited high inbreeding depression in F2. The results showed that selection in advanced segregating generations would be advantageous.
