Brassica (a cross of Brassica oleracea and Brassica rapa) belongs to Brassicacea family ranked the third most important source of edible oil and covers more than 15% of the world’s edible vegetable oil. In this study, the performance of various Brassica varieties was evaluated concerning quantitative and morphological characters and to identify the botanical descriptions of Brassica species. Six Brassica accessions were evaluated for their morphological characters and their related traits. The experiment was conducted following a Randomized Complete Block Design (RCBD) with three replications. The data was recorded on quantitative traits i.e. germination, plant height, number of leaves, leaf length, leaf width, number of Silique, number of primary branches, number of secondary branches, number of seeds per plant, and 1000 seed weight. Recorded data were subjected to analysis of variance, and correlation to evaluate the performance of various Brassica varieties concerning quantitative characters and to identify the botanical and morphological descriptions of Brassica species among various traits in Brassica. The accession, Uaf16, was a comparatively better-performing accession among all selected accessions. Plant height, leaf length, and no. of seeds had a significant and positive correlation with leaf width and seed weight. Whereas, seed weight has a negative significant correlation with plant yield, primary and secondary branches showed a negative significant correlation with R1. R1 which is the leaf length/width ratio has a significant positive correlation with plant yield, and seed weight and a significant negative correlation with leaf width. All the traits showed a positive direct effect on seed yield except plant height.
