Breeding of winter rapeseed in VNIIMK: history and new results (review)

Breeding of winter rapeseed in the V.S. Pustovoit All-Russian Research Institute of Oil Crops was started at the end of 60th of previous century with a selection of perspective winter forms from hybrids of spring brown mustard and winter rapeseed. Hetero-sis in intraspecific hybrids was studied. The best intraspecific hybrids exceeded the parental forms by 20-36% by seed yield, by 20-27% by green mass yield. A possibility to create intervarietal hybrids based on heterostyly was studied. Conditions for plants acclimation to increase cold resistance of winter rapeseed were studied; methods of selection for cold resistance were developed. In 1982, the development of rapeseed and turnip rape cultivars of ‘00’ type began. To create diversity of breeding germplasm, a great amount of samples from European counties that actively deals with rapeseed breeding were included into the work. In the V.S. Pustovoit All-Russian Research Institute of Oil Crops, the methods of estimation of oil and fodder protein quality were perfected, cultivars of rapeseed and turnip rape of ‘00’ type (e.g. erucic acid free and with low glucosinolate content) were developed. As a result of breeding for oil quality, high oleic cultivars were developed, that not only improve upon the oil nutritive efficiency but open new possibilities of its technical uses due to increasing oxi- and thermostability. The first Russian high oleic winter rapeseed cultivar Olivin was developed in the V.S. Pustovoit All-Russian Research Institute of Oil Crops and introduced in the State Variety Commission in 2019. The linear cultivars of winter rapeseed were developed by inbreeding, the first interlinear hybrids - using a CMS Ogura system. One of them named Debyut was introduced in the State variety trials 2020.
