Combining Ability Study in Pigeonpea (Cajanas Cajan (L.) Mill.) under Different Environments for Yield Contributing Characters
Abstract
The experimental materials comprised of eight divers parents. Twenty-eight crosses along with parents were evaluated during kharif 2023-24 at three environments (three different date of sowing) in three replications. Results revealed that higher magnitude of sca variance over gca variance for all the traits which indicated preponderance of non-additive gene action. The parents ICPL-20338, ICPL-20340, Pusa-992, ICPL-87 and PA-16 were good general combiners for seed yield and its two or more component traits. The estimates of sca effects revealed that eleven crosses out of twenty-eight cross combinations showed significant positive effects for grain yield per plant and its related traits.
