Study on the inheritance of oleic acid content in reciprocal F₁ hybrids of winter rapeseed at V.S. Pustovoit All-Russian Research Institute of Oil Crops

Abstract The purpose of the research was to study inheritance trait oleic acid content in oil winter rapeseed seeds reciprocal F1 hybrids. We carried out 2019-2020 under field and greenhouse conditions. used two high lines for hybridization: BH 1844 (82.2 %) 1848 (83.0 %), high-yielding from varieties Sarmat Selegor with a standard level 62.1 60.5 %, respectively. Analysis C18:1 hybrids, conditions, showed that case crossing Selegor, five eight combinations had an intermediate type (h/d -0.10 0.28). In remaining three cases there incomplete dominance 0.56 0.64). similar studies phytotron complex. On average, conditions 5.5 % lower lines, 0.3 variety Sarmat, 0.9 as is synthesized less intensively at low air temperature. All -0.43 0.48). With this inheritance, combining yield can be isolated future.
