Embodiment 1

[0063] Embodiment 1, a kind of breeding method of the wheat that yield and quality improve

[0064] The following two combinations are used as an example to filter:

[0065] Combination 1: Combination of Ji 954072 and Jinan 17

[0066] Combination 2: the combination of Jimai 954072 and Jimai 19.

[0067] 1. Breeding method of wheat with improved yield and quality

[0068] 1. Identify whether the parental combination contains proteins related to yield or quality

[0069] 1) Protein level detection

[0070] Extraction of glutenin from tissues of Ji 954072, Jinan 17 and Jimai 19 (Ji Jun, Liu Dongcheng, Wang Jing, et al. A method for extracting high and low molecular weight glutenin subunits from wheat[J]. Genetics, 2008, 30( 1):123-126.), SDS-PAGE detection.

[0071] Chuanmai 56 and Chinese spring were used as standard controls.

[0072] The SDS-PAGE electrophoresis results of HMW-GS of Ji 954072, Jinan 17 and Jimai 19 are as follows figure 1 Shown, from left to right: Chu...

Abstract

The invention discloses a wheat yield and quality synergistically improving selection breeding method of the fittest. The invention provides a method for breeding target wheat varieties with improved yield and quality, which combines the advantages of the pedigree method and the hybrid method, and provides a whole-generation final selection using molecular markers combined with phenotypic identification, and each generation is selected according to different standards The selected method is different from the derivative system method, which not only retains the traceability of the lineage history and genetic relationship of the pedigree method, but also retains the characteristics of simple operation and rich genetic diversity of the hybrid method. The background of the parents before the combination is clear, the purpose of the combination is strong, the selection process is simple, the goal is clear, and it is easy to operate, especially for those who have no breeding experience, it is easier to master, providing technical support for the rapid selection of high-quality and high-yielding new wheat varieties.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a breeding method for selection of the weakest for synergistic improvement of yield and quality of wheat. Background technique [0002] Wheat has always been the main ration of people in northern my country. As the area of ​​arable land continues to decrease, increasing the yield per unit area has become the only way to ensure an increase in total output, thereby ensuring my country's food security. Faced with the improvement of people's living standards and changes in dietary structure, my country's wheat production has begun to make strategic adjustments, transforming from a simple output type to a high-quality, high-yield, and high-efficiency type. Since the yield and quality of wheat have always been recognized as contradictions, how to better coordinate the relationship between them has become an urgent problem to be solved. Although Chinese breeders have also proposed some se...
