PDFAbstract: The study centered around Brassica juncea, commonly known as Indian Mustard, renowned for its edible leaves, seeds, and oil. Focusing on nineteen mustard genotypes, the research aimed to assess genetic diversity and trait connections. Conducted during the Rabi season 2022-23 at Sam Higginbottom University's Central Research Farm, Prayagraj, the experiment adhered to a Randomized Block Design with three replications. Data collection from five plants per genotype unveiled Pusa Bold and DRMR 150-35 as top performers in seed yield per plant compared to DRMR IJ-31, the check variety. Genotype analysis showcased significant variance across all traits. Mustard germplasm displayed considerable Genetic Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV), notably in secondary branch count. Traits like siliquae number and seed yield boasted high heritability. Several traits exhibited moderate GCV, high heritability, and genetic advancement, especially siliquae number and seed yield.
