Abstract

Genetic components of variation were estimated for six Brassica napus lines using 6×6 diallel scheme. The current research was conducted in the winter season during 2019-20 in the Department of Plant Breeding and Genetics University of Agriculture Faisalabad. Statistical analysis exhibits great diversity among parental genotypes and F₁hybrids for all the investigated characters. All the characters under study manifested over dominance type of gene pattern excluding the number of primary branches/plants controlled by partial dominance type gene action. The traits like plant height, primary branches/plant, days to 50% flowering, and 1000 grain weight showed the highest dominant gene action exhibited by DGL. Genotype B-56 showed dominant gene action for siliquae per plant days to maturity and grain yield. ZMR-2 and ZM-RN possessed the highest number of dominant genes for the time taken flower completion and oil contents, respectively. Broad sense heritability had a high value for all traits (62%-85%), indicating that these traits can be used for further improvement.
