Pollination method for radish breeding materials

Abstract

The invention relates to a pollination method for radish breeding materials. The pollination method includes the steps of radish seed selection, radish planting, radish management after planting, mesh enclosure setup, thinning and supporting, manual powdering, pollination period management and seed harvesting. Radish management after planting includes watering, fertilization and pest elimination; thinning refers to cleaning radish branches in the early flowering stage of radishes and retaining 3-5 branches on each single plant; supporting refers to fixing each radish single plant and tightening the radish branches of a dispersed plant type; mesh enclosure setup refers to setting up a mesh enclosure according to the number of the materials after transplanting survival of the radishes, compacting the bottom of the mesh enclosure, fixing the outside of the mesh enclosure and mounting a wire drawing door on a narrow side of the mesh enclosure; and manual powdering refers to gradually powdering different flowers of the same plant or different single plants of the same material without pollution or damage. The pollination method is simple in process, insect pollination can be effectively prevented, mixed pollination is avoided, loss of beneficial genes of the radish materials can be avoided, and seed production cannot be affected by environmental factors.

Description

technical field [0001] The invention relates to a method for pollinating breeding materials in the crop breeding process, in particular to a method for pollinating radish breeding materials. Background technique [0002] Radish is a cruciferous vegetable, a cross-pollination crop, self-pollination is seriously degraded, and out-crossing is normal, which is determined by the biological characteristics of radish. However, in the radish breeding process, in order to achieve the breeding goal, it is often necessary to perform manual operations on the flowering stage of the breeding materials (such as selfing, sexual hybridization, etc.). On the one hand, in order to purify radish breeding materials, it is necessary to eliminate unfavorable traits through selfing (this is based on a certain population). If artificial selfing or sexual hybridization is used, the number of radish seeds obtained is limited, and the selection population of offspring will change. On the other hand, a...
