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 for two-rowed naked barley. The method comprises the following steps: using two-rowed malting barley Favrite as a female parent, using Tibet two-rowed naked wild barley ZYM0981 as a male parent, artificially hybridizing and matching, to obtain a F1'-generation plant; using a high-quality stable barley strain 9810 as the female parent, using the F1'-generation plant as the male parent, artificially hybridizing and matching, seeding F1-generation seeds in the second year; seeding the F1-generation seeds until F7-generation, selecting a stable naked barley strain, and named as a naked barley strain 0406-17. The beneficial effect is that the provided breeding method for the two-rowed naked barley has the positive effect of rapid speed and easy selection. In the breeding method, stabilization of crop characters is rapid, and crops are easy to be rapidly bred as a new variety. The bred strain has the characteristics of lodging resistance, high yield,high thousand seed weigh, wide adaptability and the like.

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...
