Abstract

Six parents (P<inf>1</inf>, P<inf>2</inf>, P<inf>3</inf>, P<inf>4</inf>, P<inf>5</inf> and P<inf>6</inf>) half diallel population of Jatropha curcas were evaluated to determine the combining ability, genetic components of variance and heterosis for yield contributing traits. Diallel analysis showed that both additive and dominance gene action was responsible for the genetic regulation of all the traits under study. The cross combination P<inf>1</inf> × P<inf>3</inf> showed the highest positive specific combining ability for seed yield per plant. Combining ability results were also in close agreement with the findings of estimate of genetic components of variance. The seeds per fruit (89%) and 100-seed weight (93%) showed maximum narrow sense heritability. Seed yield per plant showed high mid parent (254.13%) and better parent (202.36%) heterosis in the cross combinations of P<inf>2</inf> × P<inf>5</inf> and P<inf>1</inf> × P<inf>3</inf> , respectively. The parents of P1 , P2 , P3 and P5 were found to be superior for seed yield components when used in cross. Considering seed production for each plant, the hybrids P<inf>1</inf> × P<inf>2</inf>, P<inf>1</inf> × P<inf>3</inf>, P<inf>2</inf> × P<inf>5</inf> and P<inf>4</inf> × P<inf>6</inf> could be selected for the development of hybrid varieties.
