L X T Analysis of Yield Characters in Chickpea (Cicer arietinum L.) under Rice Based Cropping System

Analysis of variance for combining ability revealed that the variance due to gca were highly significant for all the characters in all the environments except for days to maturity in E1, plant height and primary branches plant-1 in E1, E2 and E3, secondary branches, seed yield and harvest index in E2 and E3, pods plant-1 in E1 and E2, biological yield plant-1 in E2 and protein content in E1. Similarly variance due to sca were highly significant for all the characters in all the environments except days to maturity in E1, plat height, primary branches plant-1 and secondary branches plant-1 in E3, seed yield plant-1 in E2 indicated the importance of both additive and non additive gene effect in their expression. The parent JG 14 and JG 16 appeared to be good general combiners for the trait seed yield plant-1 in all the three environments. JG 14 and JG 130 for pods plant-1 in E1 and E2, JG 16 and JG 130 in E3. For the trait harvest index, JG 14 and JG 16 in E1 and E2, JG 14 and ICCV 96029 in environments E3. The parents Vaibhav and JG 11 also appeared to be good general combiners for the traits protein content in all three environments. For high seed yield plant-1 the cross JG 130 x JG 97, JG 14 x JG 97, JG 315 x JG 97, JG 315 x ICCV 96029 were found as better specific combiners in all the three environments. whereas, Indira Chana-1 x JG 97 in E1 and E2, JG 11 x JG 97 in E1, Vaibhav x ICCV 96029 in E1 found as better specific combiners for the characters.
