Forty six genotypes; comprising 36 hybrids developed in diallel fashion excluding reciprocals, 9 pistillate parents along with one standard check GCH-7 were evaluated. The magnitude of both relative heterosis and heterobeltiosis was positive for seed yield and other yield contributing characters. The hybrids SKP-84 x DPC-9, ANDCP-08-01 x JP-65, ACP-1-06-07 x SKP-8 and VP-1 x ANDCP-06-07-2 were found promising. In these hybrids inter-mating of elite plants in the early segregating generations would be profitable to built up elite population for early and dwarf pistillate lines with high seed yield.
