Embodiment Construction

[0016] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0017] figure 1 It shows the implementation flow of the method for rapidly cultivating wheat materials resistant to ear germination by using complex genotype populations provided by the embodiments of the present invention.

[0018] The method includes the following steps:

[0019] Step S101, in the wheat breeding and selection nursery with complex genotypes, after selecting and harvesting the required materials according to conventional breeding, harvesting the remaining materials at an appropriate later time, so that there is a small amount of shattering of various materials, and then performing con...

Abstract

The invention belongs to the technical field of variety breeding and provides a method for rapidly cultivating a wheat pre-harvest sprouting material from a complex genotype group. Function verification is conducted directly aiming at the pre-harvest sprouting resistance, strict phenotypic selection is conducted on the pre-harvest sprouting resistance, and the bred material has very reliable and high-level pre-harvest sprouting resistance. According to the method, the technique is simple and convenient, and rapidness and efficiency are realized; a batch of materials with high pre-harvest sprouting resistance can be accurately and rapidly cultivated; the cultivated pre-harvest sprouting material can be directly used as a strain to join in test so as to cultivate a new pre-harvest sprouting type; the cultivated pre-harvest sprouting material can also be used in heredity and molecular biology study; according to the method, natural conditions are utilized for eliminating materials without pre-harvest sprouting resistance; and materials preserved till the autumn sowing comes normally have very high pre-harvest sprouting resistance, are simple in breeding process and strong in practicability, and have high popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of variety selection and breeding, and in particular relates to a method for rapidly cultivating wheat panicle-resistant germination materials by using complex genotype populations. Background technique [0002] Rain germination during wheat harvest is a frequent disaster in wheat production. Breeding varieties and materials resistant to panicle germination is the most effective and economical method to resist this disaster. [0003] The prior art provides a method for assisting the identification of white-grained wheat varieties resistant to panicle germination. The method for assisting the identification of white-grained wheat varieties resistant to panicle germination is to use white wheat varieties with the following characteristics as candidate white-grained wheat varieties resistant to panicle germination : There is wax powder on the glume, and the gap between the glume and the glume can't be seen with...
