The results of the breeding work on rapeseed in Siberia

Rapeseed is one of the leading agricultural crops in the world with a wide area of cultivation. The article shows the history of the development of rapeseed farming in Siberia and presents the results of breeding work on rapeseed. The varieties of spring rapeseed of East Siberian breeding, promising for Western and Eastern Siberia, are given. A brief description of the Uzhursky rapeseed variety is the first variety created by accelerated breeding with a low content of erucic acid. The article presents the history of zoning of the aneruk and low– glucosinolate varieties of spring rapeseed in the food direction of use Dubravinsky precocious with high seed yield up to 27.2 c/ha and oil content up to 43-45%. The history of the creation of the most famous variety of spring rapeseed Reliable 92 in the Krasnoyarsk Territory and adjacent regions, obtained by the method of diallel crosses, with a yield of green mass up to 315-380 kg/ha, seeds up to 21.9 kg/ha, with a seed content of up to 22.8% protein and up to 42-44% fat. Further breeding work contributed to the creation of a variety of spring rapeseed for complex use (for green feed and seeds) The gift and varieties of the oilseed direction of use are Siberian. Over the past 15 years, work has been carried out with variety sample No. 595, called the Ladny variety, with a yield of green mass up to 50.4 t/ha (16% higher than the standard), a dry matter content of 9.36 t/ha (12% higher than the standard), a feed value of green mass feed units – 0.148 g, digestible protein – 18.18 g, digestible protein in 1 K. unit 124.6 g. Seed yield over five years of research ranged from 1.37 to 2.58 t/ha, on average 2.01 t/ha (17.5% higher than the standard Reliable 92 – 1.71 t/ha). The new Ladny variety is recommended for cultivation in Western and Eastern Siberia.
