Problems solved by technology

When cultivating radish in summer, it is easy to encounter harsh natural conditions such as continuous high temperature, storm, drought, pests and diseases, among which the lack of heat-resistant varieties and supporting cultivation techniques is the most important, so the yield is low and unstable, and the quality is poor
[0003] At present, the main cultivar "Short Leaf 13" for the production of Shangxia radish is a conventional variety, which is not strong in heat resistance, easy to bran heart, not resistant to viral diseases, poor in stress resistance, low and unstable in yield, poor in purity and consistency, etc. shortcoming

Embodiment Construction

[0014] A method for breeding summer radish, comprising:

[0015] 1) The first-generation hybrid "Xiayou No. 1" radish was prepared by using the heat-resistant male sterile material R010108A as the female parent and the heat-resistant material R99034-5-3-3-1-3 as the male parent.

[0016] 2) R010108A is an inbred line using the heat-resistant radish "Xia Changbai No. 2" (publicly known and used in production) of Jiangsu "Zhengda" company as the sterile source, and using the local variety "Locomotive radish" in Guangdong Province (known and used in production) (Transferring started from the 3rd generation of the inbred line, and continued selfing of the inbred line at the same time, and now it has reached the 8th generation) R010108 is the transgenic material. Characteristic characteristics, but also to maintain sterility) the stable sterile line R010108A, which was transformed for 5 generations, has a sterility rate and degree of sterility of 100%; the inbred line R010108 is a ...

Abstract

The present invention is summer radish variety breeding process and belongs to the field of plant variety breeding technology. The radish hybrid Xiayou-1 is bred with male sterility line R010108A, which is transfer bred with Xiachangbai-2 of Jiangsu Province as sterile source and Huochetou Radish of Guangdong Province, as female parent and Duanye-13 as heat tolerant variety as male parent. The radish hybrid Xiayou-1 is the first filial generation heat tolerant radish with white peel and white pulp capable of growing normally at high temperature field condition in summer, and has high uniformity, less becoming spongy, high resistance, high yield and high quality.

Description

1. Technical field [0001] The invention relates to a summer radish breeding method, which belongs to the technical field of plant breeding and is specially used for breeding heat-resistant radish hybrids with white skin and white meat. 2. Technical background [0002] Radish production takes autumn as the main production season, and there are many varieties suitable for cultivation in autumn, and the corresponding cultivation measures are relatively perfect. When cultivating radish in summer, it is easy to encounter harsh natural conditions such as continuous high temperature, storm, drought, pests and diseases, among which the lack of heat-resistant varieties and supporting cultivation techniques is the most important, so the yield is low and unstable, and the quality is poor. [0003] At present, the main cultivar "Short Leaf 13" for the production of Shangxia radish is a conventional variety, which is not strong in heat resistance, easy to bran heart, not resistant to vir...
