ABSTRACT
Cauliflower (Brassica oleracea L.) is one of the major cruciferous crops in Pakistan. It contributes significantly in the food security of country. This study aimed to evaluate different commercially grown cauliflower cultivars including three hybrid and two non-hybrid ones at seedling stage to assess their genetic variability and association of plant characters. The experiment was conducted in pots and 40 days-old healthy seedlings were selected for the study. Parameters studied included days to emergence, germination percentage, shoot length, root length, fresh seedling, shoot and root weights with dry seedling, shoot and root weights. Means, genotypic and phenotypic variation, heritability, genetic advance and correlation analysis were done for these characters. The phenotypic for germination percentage is 208.52 and genotypic variance is 254.44. For all the characters the phenotypic variance (PV) is greater than genotypic variance (GV) and phenotypic coefficient of variation (PCV) is greater than genotypic coefficient of variation (GCV). Days to emergence had negative correlation (-0.690) with germination percentage, and (-0.817) with root length. Hybrid seedlings showed early emergence, mostly in three days post-sowing. Overall, the results of this study demonstrated that hybrid cultivars of cauliflower perform at par with non-hybrid ones, providing baseline data for future vegetable breeding programs.
