A pedigree method in breeding of rapeseed and mustard in VNIIMK: general ideas, scheme, modification

A pedigree method is used in breeding works with rapeseed and mustard in the V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK). The general idea of this method is estimation of genetic potential of an individual self-pollinated plant by progenies. Usage of individual selection of valuable genotypes combined with self-pollination allowed breeders of the institute starting development of linear varieties. The purpose of the work is to describe methods and schemes in rapeseed and mustard breeding in the V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK). The presented material showed results of a usage of the modified method of pedigree in breeding of Brassicaceae oil crops during last 15 years. Developed linear varieties of winter rapeseed exceed OP-varieties on seed yield by 0.87 t per ha, on oil content - by 1.7% and on oil yield - by 0.44 t per ha. Varieties of brown mustard developed by pedigree method using inbred lines demonstrated advantage on seed yield by 0...
