The results of preliminary trial experimental hybrids of winter rape-seed bred at VNIIMK by economically valuable traits

The purpose of the research was a preliminary estimation of ten experimental hybrids of winter rapeseed (Brassica napus L.) bred in the V.S. Pustovoit All-Russian Research Institute of Oil Crops by the primary economically valuable traits. The research was conducted in the central zone of the Krasnodar region in 2019-2020. The results of the research are presented for the first time. On average for two years, nine of ten the best experimental hybrids increased by seeds yield by 0.32-0.76 t per ha both the standard cultivar Loris and the foreign hybrid Mercure. Middle seed yield of the studied hybrids varied significantly, variance range was from 4.99 t per ha (VN-3 х OPK-10) to 5.62 t per ha (VN-4 х OPK-20). Maximal values of seed and oil yields per a unit area were fixed for a hybrid combination VN-4 х OPK-20. Except that, the hybrid is characterized with high weight of 1000 seeds (4.5 g). A hybrid combination VN-13 х OPK-10 demonstrated high average by years seeds yield (5.33 t per ha) and oil yield (2.25 t per ha).Oil content in seeds and weight of 1000 seeds of this combination were at the level of the standard cultivar and the foreign hybrid. This hybrid shows the lowest glucosinolate content in seeds - 16.7 μmol/g, that is less that the foreign hybrid Mercure has by 2.3 μmol/g. The preliminary conclusion based on our researches is: the selected hybrids after confirmation of the competitive trial results can be of a great interest for production.
