This research was conducted to assess genetic evaluation between Brassica advanced lines for qualitative traits. Twenty-two Brassica genotypes (sixteen advanced lines and six checks) were evaluated in randomized complete block design with three replications at The University of Agriculture, Peshawar during 2021-22 crop growing season. Significant (p≤0.01) differences among overall genotypes, advance lines, checks and advance lines vs. checks were observed for all studied traits except pod width and protein content. The genotype G06 showed highest value of 48% for oil content, while highest value for protein content of 24% for G20. The Genotype G13 and G19 showed lowest value for glucosinolate content and erucic acid content (47 and 23), respectively. High heritability estimates were observed for erucic acid (0.85), glucosinolate content (0.78), oleic acid (0.77), linolenic acid (0.69), and moisture content (0.61). High genetic advance as a mean percent was manifested for erucic acid (28.0%), glucosinolate content (24.86%) while moderated genetic advance values were recorded for linolenic acid (17.59%) and oleic acid (17.18%). The study also revealed that genetic factors played a significant role in determining glucosinolate content and oleic acid content, making them suitable targets for selective breeding. On the basis of superior performance, G18, g06, G03, g05, g13, g19 and g20 are recommended for growing growers to high yielding Brassica cultivars.
