Abstract

                                The extent of heterosis for yield and yield and yield contributing components were studied in a set of 30 crosses involving a genetic male sterile line and 30 genetically diverse plant types of indeterminate and determinate types of Pigeonpea. Five cross combinations using male parents L.297, F21.M, OP.SP.L.Brown, S.Brown, L.298 and MS Prabhat. DT as female parent were identified as the best hybrids for grain yield on the per se performance with high heterotic expression. Development of hybrids using parental combination of determinate and indeterminate types would yield good hybrids vigour. High heterosis for traits like pods/plant, number of primary branches and grain/plant had influenced the grain yield.
