Phenotypic and genotypic coefficient of variability, heritability in broad sense and genetic advance were determined investigating the characters of 15 accessions of Silybum marianum. Seed yield/plant and number of capsules/plant had highest estimates of genotypic variation, heritability and genetic advance which suggest that direct selection for these traits is suitable for the improvement of this crop. Number of capsules/plant had a significant positive correlation with the number of branches/plant and leaf length(r=0.3398, 0.7547), whereas seed yield/plant had a positive significant correlation with leaf length, stem diameter, capsule diameter and silymarin content (r=0.6830, 0.3140, 0.3484, 0.2925).
