To evaluate the biochemical characteristics of rapeseed-mustard oilseeds genotypes were studied their seed weight, moisture content, and oil content. Significant variation was observed among the genotypes for all the evaluated traits. The thousand seed weight was varied between 2.21 to 6.05 g. Among the varieties the highest thousand seed weight was found in GM3 and the lowest thousand seed weight was found in PBN2001. The highest moisture content was observed from PC5 (5.29%); whereas the lowest moisture content was found in BCRS3 (3.10%). The variety GM1 contained significantly highest amount of oil (41.67%) with GM1, GM3, and GDM4 identified as high oil content genotypes whereas the variety BHC-46 contained lowest amount of oil (17.51%), Substantial variation was observed among the genotypes, highlighting the potential for genetic improvement and selection in oilseed Brassica crops. GM3 exhibited the highest thousand seed weight and one of the higher oil contents, suggesting a possible positive association. Conversely, genotypes with lower seed weight and higher moisture content generally exhibited reduced oil yield, indicating complex interrelationships between these traits.
