Genetic architecture of dual purpose pigeonpea

The present investigation was undertaken with a view to know the extent of heterosis combining ability G x E interactions and stability parameters for dual purpose pigeonpea [Cajanus cajan (L.) Millsp.]. The hybrids were developed by adopting complete diallel mating design involving a set of 36 pigeonpea entries including six parents 30 crosses and two parental inbred-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 during kharif - 2014. On the basis of per se performance heterosis combining ability estimates and stability involved in the expression of yield and its components the parent AVPP-1 and the hybrid AVPP-1 x GT-1 (G x A) was identified as superior for future breeding programme.
