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 method for breeding radiant barley. The process includes: screening the germplasm resources of radiant barley to obtain high-quality radiant barley germplasm resource Ji 53, using Ji 53 as the male parent and Fawavit as the female parent to perform hybridization , Harvest the seeds, get the F1 generation, self-cross the F1 generation, get the F2 generation, and so on, in the F7 generation, select the bright and stable lines to get the bright barley. The invention selects and breeds a new variety of radiant barley with good quality through hybridization, and improves the yield and stress resistance of the barley.

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...
