Breeding method of hybrid black naked barley

Abstract

The invention provides a breeding method of hybrid black naked barley. A naked barley sterile line 'Mingxing wheat No.4' with glume opening and blooming and anther external hanging in a heading periodis taken as a female parent, black naked barley 16-260 with glume opening and blooming and anther external hanging in the heading period is taken as a male parent, the female parent and the male parent are subjected to hybridizing and matching, seed production is carried out for the male parent and the female parent, the male parent is sown by stages, the male parent is sown in two stages so as to prolong the flowering period of the male parent and facilitate flower synchronization, the male parent and the female parent are respectively harvested during harvesting, the male parent is harvested in advance before maturation, and the female parent is independently harvested after maturation, such that first-filial generation seeds used for production are obtained, and can be used for producing 19W20 hybrid black naked barley, and the 19W20 hybrid black naked barley has characteristics of larger grain and higher yield. Meanwhile, the hybrid black naked barley also shows biological advantages, the plant shows wider leaves, and when the hybrid black naked barley is used as silage, the proportion of the leaves in the whole plant is relatively larger, so that the hybrid black naked barleyis more popular in farms.

Description

technical field [0001] The invention relates to a breeding process of barley, in particular to a breeding method of hybrid black barley, which belongs to the technical field of crop breeding and is specially used for the production of black barley. Background technique [0002] With the continuous improvement of people's living standards, people's demand for food is becoming more and more diverse. Black barley food has been very popular in the market in recent years. Therefore, breeding new varieties of black barley with high yield and high quality has become the task of breeders. One, the current domestic production of black barley is not high, and hybrid black barley has not been reported yet. Contents of the invention [0003] The invention is a black barley breeding method proposed aiming at the problem of low yield of black barley in China. The bred black barley variety not only has high yield, but also has large grains and is suitable for processing. [0004] The te...
