The information of the relative degree of genetic variance components is fundamental in the selection of appropriate breeding methodologies. The diallele analysis is the quickest method to enable predictions to be made based on early generations, which could greatly increase the efficiency of breeding programs. Component analysis revealed that additivedominance model fitted only for number of sympodial branches per plant in both the generations under all the three environments. The present study indicates the preponderance of dominance components for inheritance of this character. Heritability values in the narrow sense for this character varied from low (17.50 % in E2 F1) to moderate (46.58% in E2 F2). Since both additive and non-additive types of gene actions were present in different proportions, reciprocal recurrent selection is suggested for the improvement of the character.
