Examine how clusterbean (Cyamopsis tetragonoloba (L.) Taub.) branching habit and bearing pattern are inherited.

Abstract

The goal of the current research was to determine how two traits—branching behaviour and bearing pattern—were inherited in the F2 segregating population of clusterbean [Cyamopsis tetragonoloba (L.) Taub]. F1 seeds from three distinct crossings and clusterbean parents, namely F5 × RGC-1066, PNB × CAZG-16-10-3, and IDB-29-2 × BSL (11×15), comprised the original experimental material. The segregating progenies were grown at a distance of 20 cm between plants and 50 cm between rows. Every F2 segregating plant in a cross was tagged, and observations were made on a regular basis until the phenotype was confirmed. The chi square approach was used in the statistical study to determine the genetic ratio's goodness of fit for the various gene actions implicated in these segregating populations. In two segregating F2 populations, PNB × CAZG-16-10-3 (9:6:1) showed polymeric gene action, F5 × RGC-1066 (9:3:4) showed supplementary gene action, and IDB-29-2 × BSL (3:1) showed branching and bearing pattern controlled by one pair of genes with monogenic inheritance, according to the current study.
