Abstract

Inheritance pattern of some polygenic characters were studied in 5 x 5 F1 diallel hybrids and their parents of upland cotton. 20 F1 hybrids and their parents were grown in field under randomized complete block design at experimental area of the Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad. Diallel analysis was used to determine the mode of gene action and genetic components for various yield related traits like plant height, monopodial branches plant-1, sympodial branches plant-1, bolls plant-1, boll weight and seed cotton yield plant-1. Results of regression coefficients showed that all the characters were fit for genetic analysis. Additive type of gene action with partial dominance and over dominance were involved for the expression of the traits studied. Results suggested that these characters can be improved through appropriate selection method or by hybrid development.
