INHERITANCE STUDIES OF PLANT BRANCHING PATTERNS IN DIFFERENT CROSSES OF PIGEON PEA (CAJANUS CAJAN L.)

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.
