Type: article
Abstract: In the pigeon pea (Cajanus cajan), the inheritance patterns of plant branching types were examined.The results showed that three branching classes erect, semi-spreading, and spreading affected yield.Semispreading patterns were seen in both the parental and F 1 generations.GRG-152 x C.G. Arhar 1 segregated into 26 erect, 96 semi-spreading, and 42 spreading plants (9:3:4 ratio) in the F 2 generation, indicating supplementary gene action.Rajeevlochan × C.G. Arhar 1 showed 136 erect, 275 semispreading and 26 spreading plants (9:6:1 ratio), suggesting polymeric gene action.Crosses GRG-152 × Rajeevlochan and its reciprocal i.e, Rajeevlochan × GRG-152 resulted in 12, 7 erect, 275, 214 semispreading and 50, 52 spreading plants (12:3:1 ratio), demonstrating masking gene action.Chi-square tests for the crosses (GRG-152 × C.G. Arhar 1, Rajeevlochan × C.G. Arhar 1, GRG-152 × Rajeevlochan, and Rajeevlochan × GRG-152) yielded values of 0.6103,8.27,8.6103 and 6.36 respectively, all below the critical value range of 0.025% to 0.005%, indicating the validity of the observed ratios.These discoveries about genetic pathways offer implications for breeding and yield optimization in pigeon pea.
