Oilseed rape (OSR) or rapeseed – Brassica napus L. is the most important plant of genus Brassica, grown for its oil content. Breeding of new rape varieties without eruc acid content (“0” type) and low-glucosinolytic content (“00” type) is a prerequisite for the cultivation of this crop in more countries and on increasingly larger areas. The recent gradual re-introduction of rapeseed in our country turned it into a successful crop. The potential of the introduced winter and spring rape varieties was investigated. The technology for new varieties and hybrids grown in Europe and worldwide was studied and improved. New initial material was collected and eaxamined as a basis for the resumed breeding of rapeseed in Bulgaria. The research work was directed towards developing parental forms and using heterosis in rapeseed.
