Abstract

Since the end of the fifties the main aim of genetics and plant breeding for WOSR was grain and oil productivity to provide unsatisfied markets for oil as well as for animal feeding. In the following periods others objectives were added in the field of product quality and resistance to diseases. After an historical perspective of the crop development and the parallel evolution of breeding technics, we will set a balance sheet of the genetic progress reached. For several years now, breeding objectives are more diverse coming from market diversification, regulations behavior, or societal wishes. Genetics and plant breeding have specifically an important role to play in the field of new plant protection strategies. Today strategies will be carried out to satisfy such aims through wider genetic diversity exploitation, and genotyping and phenotyping methods improvements.
