Abstract
The current study was carried out on the experimental fields of SES, a branch of VNIIMK in 2021–2023. The purpose was to estimate spring rape varieties and hybrids of various ecological and geographical origins based on the main economically valuable traits, to identify the most productive and adapted to the conditions of Western Siberia. The objects of the study were 16 varieties and hybrids of domestic and foreign breeding. The variety ‘Yubileiny’ and the hybrid ‘Ozorno’ were used as a standard. There was established that environmental testing of spring rape varieties and hybrids made it possible to identify significant differences in the main economically valuable traits. In the conditions of Western Siberia, among the rape varieties, the maximum productivity over three years of study was demonstrated by the varieties ‘Yarky’ (2.50 t/ha), ‘Sibiryak 60’ (2.43 t/ha) and ‘55region’ (2.42 t/ha), and among the hybrids ‘PR46X75’ (2.68 t/ha) and ‘Salsa KL’ (2.57 t/ha) were the best according to this indicator. The highest seed productivity was obtained in 2021 and ranged from 2.51 to 3.29 t/ha for varieties and from 3.02 to 3.52 t/ha for hybrids. High oil content in seeds was noted under the conditions of 2022 in such varieties as ‘Granit’, ‘55region’, ‘Yarkiy’, ‘Amulet’, ‘Geros’ and amounted to 51.2–52.6 %. With a short vegetation period of up to 85 days, the varieties ‘Amulet’, ‘Ruyan’, ‘Erebus’ and ‘Forpost KL’ were identified as early maturing varieties. Middle maturing varieties with a vegetation period of 88–90 days included ‘Granit’, ‘Yarkiy’, ‘Prometey’ and ‘Geros’. The plant height varied from 80 to 101 cm for hybrids and from 88 to 120 cm for rape varieties. The trait ‘1000-seed weight’ varied from 3.6 to 4.2 g. The varieties ‘55region’, ‘Sibiryak 60’, ‘Yarkiy’, ‘Amulet’, ‘Prometey’ and ‘Forpost KL’ were of greatest interest for practical breeding according to the complex of economically valuable traits in the southern forest-steppe of Western Siberia.
