Changes of rapeseed (\kur{Brassica napus} L.) cultivar composition during breeding of this crop
 LHOTA, Jiří
The work maps the development of oilseed rape (\kur{Brassica napus} L.) breeding in terms of changes in the varietal composition. Changes in the variety composition mainly concern the setting of breeding work to reduce the content of undesirable fatty acids (erucic acid) and antinutritive substances (glucosinolates) in rapeseed. There are also hybrid varieties that have prevailed over linear varieties in recent years due to higher yield potential. Furthermore, the work presents the benefits of breeding work by transgenic varieties that have increased resistance to pathogens, pests and varieties tolerant to herbicides. The work is also focused on yield parameters such as seed yield and oil content. Due to the worldwide importance of this crop, the history of cultivation is mentioned both in the Czech Republic and abroad.
