Problems solved by technology

Therefore, in order to alleviate the shortage of feed, it is urgent to develop feed resources such as barley, wheat, oats, rye, etc. to replace corn, soybeans, and alfalfa, so as to alleviate the contradiction between supply and demand in the feed market. , but the palatability of toothed barley is poor after silage, which limits the application of barley, while the palatability of radiant barley is better after silage, which can improve the appetite of livestock to a certain extent

Embodiment 1

[0027] A method for breeding bright barley, comprising the following processes:

[0028] 1) Screen the agronomic and economic traits of the radiant barley germplasm resources at home and abroad. The screening criteria are: growth period 95-105 days, plant height 80-85 cm, ear length 8-10 cm, number of grains per ear ≧ 25, adult The number of panicles ≧3 / plant, 1,000-grain weight≧45g, compact plant type, good color change at maturity, high uniformity, strong lodging resistance and strong disease resistance of the plant obtained the high-quality radiant barley germplasm resource Ji 53;

[0029] 2) High-quality barley Fawavit was used as the female parent, and Guangguang barley germplasm resource Ji 53 was used as the male parent. Artificial hybridization was performed. Before hybridization, the female parent was emasculated, and 6 plants were selected, and each plant only detasseled one ear. Male, obtain enough hybrid seeds, uniformly mixed and harvested when the grains mature, ...

Abstract

The invention discloses a breeding method of Guangmang barley. The process comprises the steps of screening Guangmang barley germplasm resources to obtain superior Guangmang barley germplasm resourceJi 53, performing hybridization by using the Ji 53 as male parents and Favori t as female parents, harvesting seeds to obtain F1 generations, performing selfing on the F1 generations to obtain F2 generations, performing similar operations, and selecting Guangmang strains stable in traits in F7 generations to obtain the Guangmang barley. According to the breeding method disclosed by the invention,Guangmang barley new species good in quality are bred through hybridization, and the yield and the stress resistance of barley are increased.

Description

technical field [0001] The invention relates to the technical field of barley breeding, in particular to a method for breeding bright barley. Background technique [0002] my country has become the world's largest producer and consumer of feed, but there is a serious shortage of feed resources in our country, and the dependence of feed raw materials on imports is very large. In 2018, my country imported 88 million tons of soybeans, 3.107 million tons of corn, and 1.384 million tons of alfalfa. With the development of the feed industry, the rigid demand for feed grains such as corn and soybeans will increase year by year. [0003] In response to the current shortage of feed resources, the No. 1 Central Document of 2019 mentioned vigorously developing the production of scarce and green high-quality agricultural products, promoting agriculture from increasing production to improving quality, developing high-quality forage production, and accelerating the selection and promotio...
