Crossbreeding and propagation method of Yingzi No.1 wheat

Abstract

The invention relates to a crossbreeding and propagation method of Yingzi No.1 wheat. The method comprises the following steps: (1) selecting Mimai No.6 wheat as a female parent and Mimai No.7 wheat as a male parent for hybridization; (2) castration is performed on the female parent, pollination can be performed after stigmas are mature after 1-3 days, young embryos are stripped after 25-28 days of pollination and cultured in vitro, and F1-generation wheat seeds are obtained; (3) vernalization treatment and generation-adding propagation are carried out on the F1-generation wheat seeds for multiple times to obtain F4-generation wheat seeds; vernalization treatment is carried out on the F4-generation wheat seeds, directional cultivation is carried out, and the Yingzi No.1 wheat is obtained.According to the method, the seed consumption per mu can be reduced by about 30%, the yield is increased by 10% or above on the original basis, and the wheat quality can be improved.

Description

technical field [0001] The invention relates to a plant breeding and propagation method, in particular to a hybrid breeding and propagation method of Yingzi No. 1 wheat Background technique [0002] Wheat is a gramineous plant widely planted in the world, and it is the food crop with the second total output in the world, second only to corn. About 40% of the world's population takes wheat as their main food. my country is the world's largest wheat producer and consumer, and the development of wheat production plays an important role in ensuring my country's food security and market demand. my country is the world's largest wheat producer and consumer, and the third largest grain crop in China, accounting for 17% of the world's total wheat production and 16% of total consumption in that year. Its production is of great significance to ensuring national food security. [0003] However, with the improvement of people's living standards and the continuous increase in the cost o...

Problems solved by technology

[0003] However, with the improvement of people's living standards and the continuous increase in the cost of labor and production materials, wheat production is facing the challenges of improving quality, reducing costs and protecting the environment; Healthy wheat products have higher and higher requirements, and high-quality varieties of wheat cannot fully meet market demand; the increase in the cost of labor and production materials has increasingly limited the competitiveness of the wheat industry
