Производство семян гибридов F1 рапса в сетчатых изоляторах при различных способах опыления

Abstract

Spring rape is a valuable oil and fodder crop, a source of high-quality vegetable oil and feed protein. The basis for obtaining a high yield of seeds of rape, under the cover of mesh insulators is high-quality pollination of plants. In this regard, a comparison was made of the efficiency of pollination by forced ventilation, pollination by bumblebees and bees and open pollination at the All-Russian Scientific Research Institute of Rapeseed from 2017 to 2018. In insulators where pollination was carried out by insects, the mass of seeds from one plant and the number of seeds in the pod were higher than in plants from insulators in which pollination was carried out by forced ventilation and open pollination. At the same time, in insulators where plants were pollinated by forced ventilation and open pollination, the plant height, the number of pods per plant, and the mass of 1000 seeds exceeded those of the insulators where pollination was carried out by bumblebees and bees. Thus, mesh isolators can maintain the genetic purity of the original parental forms, provide the production of hybrid seeds with high sowing and yield characteristics.
