Edible oil is the basic constituent of human diet. Pakistan is spending huge foreign exchange for importing edible oil. So, there is dire need to focus on the research of oil seed crops to improve the production of oil. Present experiment was conducted in this context on seven Brassica napus L. accessions. Present study was, therefore, conducted to determine genetic basis of variation and hybrid vigor for various oil and quality attributing traits in order to identify promising parents which can be further used for the improvement of B. napus. For this purpose, following genotypes; Long silique, Legend, ZM-5, ZMR-4, ZM-17, Dunkeled and cyclon crossed in all possible combination by using full Diallel fashion through careful pollinations.  Among parents and crosses, maximum mean value for oil contents and oleic acid was given by ZM-17 and Dunkeled × ZM-17 respectively. Among parents and crosses, maximum mean value for linolenic acid contents is given by Legend and ZM-17 × Dunkeled. For protein contents the Zm-5 and ZM-5 × ZM-17 performed superior from rest of all genotypes.
