Rapid propagation method of radish breeding material

Abstract

The invention discloses a rapid propagation method of radish breeding material. The method comprises the following steps: (S010), mesh enclosure setting up, namely respectively matching, assembling, connecting and fixing long rods, cross rods, vertical columns, three-way connecting rings and vertical column bases; (S020) radish parent material planting, namely respectively, sequentially and intensively planting male parent and female reproduced by parent of radish sterile line and radish hybridized combination according to a certain line number; (S030) radish flowering phase management, namely removing heteromorphic plant after transplanted radish plant survives, removing fertile plant and keeping sterile plant for a sterile line from radish bolting to an initial flowering phase, keeping completely fertile plant with typical shapes and normal floral organs for maintainer line and male parent line, and applying insecticide for one time 7 to 10 days before osmia is released; (S040) osmia release and management, namely putting osmia into a mesh enclosure in the initial flower stage of radish, ensuring that osmia performs open pollination, and recycling and storing the osmia after pollination; and (S050) seed harvesting. The method is simple to operate and low in cost, and can obviously improve the seed output.

Description

technical field [0001] The invention relates to a rapid propagation method for enlarged propagation and seed production of crop breeding materials, in particular to a rapid propagation method for radish breeding materials. Background technique [0002] In the process of radish breeding, with the increase of generations of radish materials, the excellent traits of radish inbred lines tend to be homozygous and stable under artificial and purposeful selection, so it is necessary to increase the number of seeds to meet production needs. Mature sterile lines, maintainer lines, and male lines (inbred lines) formed by the three-line breeding of radish can be used for production, but it is necessary to expand the seed quantity of the sterile lines, and the sterile lines must be propagated; In order to produce a large number of hybrid radish seeds to meet the needs of experiments at all levels, effective methods must be adopted for the combination of advantages formulated in the expe...
