Title: Heterosis for yield and yield attributing traits in castor, Ricinus communis L.
Abstract: Heterobeltiosis and standard heterosis for seed yield and its attributes was studied in 40 hybrids developed through line x tester mating design (5 pistillate lines and 8 pollen parents) in castor. The significant positive heterosis over better parent (BH) and standard heterosis (SH) for seed yield ranged from -49.22% to 141.32% and -55.27% to 17.10%, respectively. The cross combinations ACP 1 x JI-35 (17.10) and JP 65 x Vl-9 (13.82) exhibited significant positive standard heterosis over GCH 4 for seed yield/plant. These superior crosses also exhibited significant and positive heterosis for number of capsule/primary raceme, number of effective branches/plant and length of primary raceme. Hybrid vigour of superior crosses may be exploited commercially after verifying the stability performance across the environments over years.
