Heterosis in greengram

Abstract

Five elite strains (P. S. 7 X Madira, PLMB 9, Pusa Baisakhi, E.C 1653) and their 10 cross combinations were compared in an experiment adopting a randomised block design with 3 replications. The study revealed that parents showed {\ >< • ; cross compatibility. Significant positive heterotic vigour over better parent was exhibited for the number of leaves, number of pods, length of pod and grain yield. Negative heterosis was noticed in the case of 100 seed weight. The magnitude of heterosis varied in different parental combinations. The heterosis in yield noticed is through heterosis in yeild components viz. number of branches per plant, number of pods per plant and number of clusters per plant.
