Genetic variability between several Brasicaceae populations of different winter survival ability
Winter survival is an important characteristic for winter rapeseed. It is known that other cold-regulated traits, such as freezing tolerance and flowering time, can modify the ability of winter survival, they all lay in the same QTL regions. Twenty varietal populations of winter rapeseed, with mean winter survival from 50 to 100％, were chosen for the investigation. In order to increase genetic variability for winter survival, 5 spring rapeseed, thre B. oleracea (winter forage kale), one B. rapa populations were also investigated.The investigation of genomic DNA polymorphism was done with 6 SSR markers, positioned in QTL regions for winter survival, freezing tolerance and flowering time.The aim of our work was to check the suitability of selected SSR markers for screening of winter survival ability and to identify genetic variability of this genomic region in NS rapeseed breeding material.
