Method for breeding high-quality wheat

Abstract

The invention relates to a method for breeding high-quality wheat. The method comprises the following steps of: hybridizing by selecting Zhengmai 005 as a female parent and Aizao 781 as a male parent, screening later generations of the Zhengmai 005 and the Aizao 781 to obtain Xufeng 998, and hybridizing by selecting Meisheng 0308 as a female parent and the Xufeng 998 as a male parent to obtain F1generation; back-crossing the F1 generation of plants and the wheat material, namely the Xufeng 998, and screening plants which are short in stalk, premature, more in tiller and good in disease resistance from one half of sterile plants; carrying out back-crossing for many times of the screened sterile plants and the wheat material, namely the Xufeng 998, and obtaining the screened wheat, namely the high-quality wheat. The bred high-quality wheat disclosed by the invention has the advantages of being hard in grain cutin, short in stalk, premature, more in tiller and good in disease resistanceand stress resistance.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to a method for cultivating high-quality wheat with hard grain cutin, short stalk, early maturity, many tillers and good resistance to disease and stress. Background technique [0002] Wheat is the staple food in people's daily life, and it is also an important source of protein in people's food. Wheat is the basis for developing the food industry and enriching the food market. At the same time, wheat is an important raw material for the development of the feed industry. Over the years, under the condition of sufficient wheat supply, domestic wheat production has paid more and more attention to the improvement of wheat quality. The sown area of ​​high-quality wheat has continued to expand, and the quality of wheat has continued to improve. However, compared with imported high-quality wheat, there is still a quality gap. . Therefore, cultivating high-yield and high-quality wheat va...

Problems solved by technology

[0004] At present, it is common to use the pedigree method to breed high-quality wheat varieties, but the breeding process is cumbersome. The genetic sterile material is used for breeding, and the method of recurrent selection is used to select sterile plants with the purpose of traits in their offspring, and they are backcrossed many times until they have The performance of the plants with the target traits is stable, and generally tends to be stable after 4-5 cycles
