Embodiment 1

[0016] A method for breeding two-row naked barley, comprising the following steps:

[0017] 1) Using two-rowed beer barley Fawavit as the female parent and Tibetan two-rowed naked wild barley ZYM0981 as the male parent, the F1' generation plants of the Fawavit × ZYM0981 hybrid were obtained, and 2 lines were sown in the F1' generation; In the process of artificial hybridization, only one ear is made for each plant when emasculation, and more than 5 ears are made. When the grains are mature, they are mixed and harvested, air-dried and stored to obtain F1' generation hybrids;

[0018] 2) Use the high-quality and stable barley line 9810 as the female parent, and the F1' generation plant of the Favavit × ZYM0981 hybrid obtained in step 1) as the male parent, artificially cross and match the group, and sow the F1 generation in the second year; during the artificial hybridization process , when emasculating, each plant only needs to make one ear, and more than five ears should be ma...

Abstract

The invention discloses a breeding method of two-row naked barley, using two-row malting barley Fawawit as the female parent and Tibetan two-row naked wild barley ZYM0981 as the male parent, artificially crossing and mating to obtain F1' generation plants; The high-quality and stable barley line 9810 is used as the female parent, and the F1' generation plants are used as the male parent. The F1 generation is sown in the second year; the F1 generation is sown to the F7 generation, and the stable naked barley line is selected and named as the naked barley line 0406. ‑17. The beneficial effects of the present invention are: the two-row naked barley breeding method provided by the present invention has the advantages of fast speed and easy selection. In this breeding method, the crop traits are stable and fast, and it is easy to quickly breed new varieties; the bred line has the characteristics of lodging resistance, high yield, high thousand-grain weight, and wide adaptability.

Description

technical field [0001] The invention relates to the field of crop breeding, in particular to a method for breeding two-row naked barley. Background technique [0002] Two-row barley is a subspecies of common barley, scientific name H. vulgare ssp. distichon Hsü. The ear shape is flat, the two-leaf barley grain has high starch content, and the malting quality is good. However, the naked barley currently planted is mainly multi-row naked barley, which has low yield and poor lodging resistance. Contents of the invention [0003] The purpose of the present invention is exactly to provide a kind of breeding method of two-row naked barley aiming at the defects in the above-mentioned prior art. [0004] In order to achieve the above object, the technical solution provided by the present invention is: a method for breeding two-row naked barley, comprising the following steps: [0005] 1) Using two-rowed beer barley Fawavit as the female parent and Tibetan two-rowed naked wild b...
