ABSTRACT
A field experiment was undertaken with a view to know the extent of heterosis for dual purpose pigeonpea [Cajanus cajan (L.) Millsp.]. The hybrids were developed by adopting complete diallel mating design (including reciprocals) involving a set of 36 pigeonpea entries including six parents, 30 crosses and two parental lines viz., vegetable purpose released variety GT-1 and grain purpose released variety Vaishali as checks in randomized block design with three replications at Bharuch, Hansot and Navsari. Significant heterobeltiosis and standard heterosis over GT-1 and Vaishali for green pod yield per plant, dry seed yield per plant and majority of the yield components suggested that there is a good scope of exploiting heterosis and also possibilities of isolating desirable segregants. AVPP-1 x Vaishali, AVPP-1 x BP-06-33 and AVPP-1 x SKNP-11-19 recorded highest heterotic values for green pod yield as well as dry seed yield per plant.
