Abstract: Lablab purpureus (L.) Sweet (Syn. Dolichos lablab L., 2n=22), self-pollinating crop, is an important legume as well as vegetable crop cultivated in India. In self-pollinated crop, variability is often created through hybridization between carefully chosen parents. The scope of exploitation of hybrid vigour will depend on the direction and magnitude of heterosis. In the present investigation, information on magnitude on heterosis were obtained for green pod yield per plant and its related components adopting full diallel analysis involving six diverse parents and its resultant thirty hybrid of vegetable Indian bean tested at Regional Horticulture Research Station, Navsari Agricultural University, Navsari during late in a randomized block design with three replications. Significant to highly significant positive heterosis for green pod yield per plant and its component characters were recorded by GNI-7 × GNI-5, GNI-5 × GNI-7, GNI-4 × GNI-7, GNI-7 × GNI-4, GNI-7 × GNI-14, GNI-14 × GNI-7 (Direct as well as reciprocals) showed high standard heterosis in positive direction for green pod yield per plants in Vegetable Indian bean. The maximum value of standard heterosis for green pod yield per plant observed for GNI-7 × GNI-5 over the commercial check (Gujarat papdi-1). The high heterotic response in this hybrid for green pod yield per plant resulted mainly due to the number of pods per plant and number of seeds per plant.
