Summary. The article presents the results of a 3-year study on the use in beekeeping of new for Siberia honey culture – winter colza, as well as data on the duration of flowering of most common in the forest steppe zone of Western Siberia honey crops as part of a flower- nectar conveyor. The main purpose of research is to develop a flower- nectar conveyor of honey grass providing continuous flowering and liquidation of early summer period without flowering. Researches were carried out in the steppe and forest-steppe zones of the Kemerovo region and in the forest-steppe zone of the Novosibirsk region on leached black earth. Climatic conditions during the study were different (from a very rainless to wetlands with a lack of effective temperatures). In determining the amount of nectar productivity of winter colza the amount of brought by bees nectar and pollen was measured daily by weighing of 2 control hives. In the development of flowers and nectar conveyor it was applied of 2-3 sowing period of Phacelia Tanacetifolia and Fagopyrum Sagittatum, taking into account the timing of flowering of Onobrychis, alsike clover. At the end of the nectar flow out of winter colza in favorable by agro-climatic conditions 2011 year on the each bee colony it was obtained from 22, and in bad years (2012,2013) – 14 kg of marketable honey. Biochemical parameters of honey from winter colza comply with GOST «Natural honey.» Organization of flower-nectar conveyor provides continuous flowering of honey crops in favorable agro-climatic conditions for 125-128 days, beginning from June 10-18. Introduction of winter colza in the conveyor allows to eliminate early summer period without flowering and lengthen the blooming of bee plants for 10-15 days.
