The results of the creation of a promising selection number of bright rapeseed No. 595 with the name assigned to it - the Ladny variety (created in collaboration with KSC SB RAS - Federal State Budgetary Institution Federal Research Center “Krasnoyarsk Scientific Center of the Siberian Branch of the Academy of Sciences of the Russian Federation” (FRBI FRC KSC SB RAS) (Krasnoyarsk) and SFRCA RAS (Federal State Budgetary Institution of Science Siberian Federal Research Center for Agrobiotechnologies of the Academy of Russian Sciences (from now on referred to as SFRCA RAS)) (Novosibirsk)). Variety sample No. 595, obtained as a result of crossing variety sample No. 198, which is a derivative hybrid of winter rapbruck (rape x WWba) and rapeseed variety Librador, Jet hef, K-4554 Gulliver, Tilde, Nora, Emma, Kendl, Torkel, Dubravinsky early ripening, Hja 82470, Uzhursky, Mary and varieties Rhythm selection of the All-Russian Research Institute of Rapeseed (Lipetsk).

In the forest-steppe conditions of the Chulym region, the yield of green mass of variety sample No. 595 increased to 45.4 t/ha, at the level of the standard, dry matter - 8.6-9.4 t/ha, forage mass - 7.4-9.5 t/ha. The green mass contains digestible protein - 18.2 g/kg, ingredients - 2.6 g/kg, phosphorus - 0.56 g/kg, digestible protein per 1 feed unit - 124.6 g, carotene - 154 mg/kg seed yield – 2.22 t/ha, which is 0.30 t/ha, or 13%, higher than the standard of the Nadezhny 92 variety, seed oil content – 41%, protein content – 28%.
