Wykorzystanie metod biologii molekularnej w hodowli jakosciowej rzepaku ozimego [Brassica napus L.]

Winter rapeseed (Brassica napus L.) belongs to the most important oilseed crops cultivated in moderate climate regions of the world. Both - rapeseed oil and seed proteins are of great value in the meaning of food industry, technology and livestock feeding. Breeding programmes are concentrated mainly on obtaining the rapeseed varieties of different quality and content of fatty acids, reduced amount of anti-nutrition compounds as well as on obtaining the high yielding cultivars and resistant to pathogenes. The results of breeding and selection are mainly due to the genetic diversity and also to analytic methods of the quality traits. Methods of molecular biology, genetic engineering and biotechnology make an efficient tool for analysis of quality traits and also for obtaining a new diversity among rapeseed cultivars.
