Thirty six castor hybrids developed by half diallel mating design (9 pistillate parents) were studied along with parents for relative heterosis and better parent heterosis of yield and yield determinate characters. The relative heterosis and heterobeltiosis for seed yield ranged from -30.09 to 383.58 and -35.04 to 267.39, respectively. The magnitude of both relative heterosis and heterobeltiosis was positive for seed yield and other yield contributing characters. The hybrids ANDCP-08-01 x JP-65, ANDCP-06-07 x JP-65 and JP-65 x ANDCP-06-07-1 were found as promising hybrids. For full exploitation of existing genetic variance in these crosses inter-mating of elite plants in the early segregating generations would be profitable to build up elite population for early and dwarf pistillate lines with high seed yield.
