A study was conducted in castor to estimate the magnitude of heterosis for yield and its eleven yield components. 32 F1 hybrids generated line × tester mating design developed by Kempthorne (1957). These F1S along with 12 parents were evaluated in a randomized block design with three replications at Agricultural Research Station at sansoli, Anand, Gujarat (India). Appreciable heterosis was found better and standard parent for all the traits studied in desirable direction. In order of merit F1 hybrids VP 1 x JC 20 (49.15 %), SKP 84 x SKI 215 (29.4%) and VP 1 x ANDCI 9 (26.93 %) were observed significant heterobeltiosis (better parent heterosis) for seed yield per plant. In case of standard heterosis, significant and positive heterosis over standard check GCH 7 for seed yield per plant was observed in hybrid VP 1 x ANDCM 2 (14.03 %) followed by SKP 84 x ANDCM 2 (13.3 %).In No. of capsules on primary spike, The VP 1 x ANDCM 2 (50.70 %)over standard check. When number of effective branches per plant, the VP 1 x JC 20 (10.3 %) over standard check.
