Awn-hooking barley breeding method

Abstract

The invention discloses an awn-hooking barley breeding method. The breeding method comprises the following steps: performing screening on awn-hooking barley germplasm resources to obtain high-qualityawn-hooking barley germplasm resource two-rowed awn-hooking naked barely and Shang highland barley, taking the two-rowed awn-hooking naked barely and the Shang highland barley as male parents and taking two-rowed barely strain 9810 as female parents to perform hybridization to obtain seeds to obtain F1 generation, taking the stable and high-quality barley strain 9406 as a female parent, taking theobtained F1-generation plant as a male parent, carrying out artificial hybridization and matching, harvesting hybrid seeds, namely a BF1 generation, carrying out selfing on the BF1 generation to obtain a BF2 generation, selecting awn-hooking single plants, performing marking, performing harvesting of the single plants, performing threshing on the single plants, and carrying out air-drying preservation; for BF3-BF6 generations, performing sowing of the selected single plants, selecting characters of the offspring single plants, continuing to select awn-hooking single plants, harvesting the single plants, threshing the single plants, and performing air-drying preservation; and carrying out selfing on the selected awn-hooking barley in the BF7 generation to obtain an awn-hooking strain withstable characters.

Description

technical field [0001] The invention relates to the technical field of barley breeding, in particular to a method for breeding Goumans 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 promoti...

Problems solved by technology

[0004] When barley is used as a feed resource, it usually needs to be silaged, but the palatability of long-mounted barley is poor after silage, and it is easy to reduce the appetite of animals. Moreover, the hardness of long-mounted barley is relatively large and difficult to digest; The palatability of awn barley is good, easy to digest, and can be used as a high-quality feed resource; however, at present, there are obvious methods for the selection and breeding of awn barley, which limits the application of barley as a feed resource to a certain extent
