New ecologically plastic spring rapeseed variety Erebus

The spring rapeseed variety Erebus was developed in 2007–2018 by individual selection in F2 from the hybrid combination LK-443-04 × LK-654-06. Ac-cording to the competitive variety trials conducted by the All-Russian Research Rapeseed Institute during 2013-2018, variety Erebus had better results than standard variety Rif in seed yield by 0.12 t/ha or 5.8% and in oil yield the results were higher by 0.08 t/ha. The content of glucosinolates in the seeds was 2.8 µmol/g lower than that one of variety Rif. In 2022, Erebus has been included in the National List of Varieties (Patent № 11441) and approved for pro-duction use in the Central (3), Volga-Vyatsky (4), Central Chernozem (5), Middle Volga (7), Ural (9), West Siberian (10), East Siberian (11) and Far East (12) regions of the Russian Federation.
