New herbicide resistant sunflower variety of oil type Buzluk Sur

Early maturing herbicide resistant sunflower variety of oil type Buzuluk sur (elite number 875) was developed as a result of the breeding and genetic program on development of sulfonylurea resistant plants at the V.S. Pustovoit All-Russian Research Institute of Oil Crops. This variety was developed using a complex of hybridization methods, backcrosses, and group repollination. A line VK1-sur was a donor of a resistance gen to tribenuron methyl ( Sur ), early maturing variety of oil type was a recipient. Subsequent individual selection with progeny estimation of the best by its morphological and economically valuable traits families and a control of herbicide resistance on the all stages of a breeding process allowed creating a population resistant to tribenuron methyl. The new variety is designed for cultivation in the production system Sumo and ExpressSun.
