[0016] Breeding process and breeding methods, including a detailed description of the pedigree, breeding process and origin and designation of the parents or other breeding material used

[0017] (1) The breeding process of 96717 (the utilization value and development strategy of black barley, Zhang Mingsheng et al., Barley Science, P.9, NO.1, 2001): it is a stable strain bred by Jiangsu Coastal Area Agricultural Science Research Institute, The parental combination is based on (Aobi Damai×Subei No. 1) as the female parent, and the environmental sterile material as the male parent. The group was mated in the spring of 1992, and the second-generation dry seeds of the hybrid were taken in the autumn of 1993 and irradiated with cobalt 60. The measurement was 30,000 roentgens. Its purpose is to breed early-maturing, short-stalked, high-yielding, black-husk barley. In 1996, a stable line was bred, which showed black-hulled, short-stalked, high-yielding barley, low thousand-grain weig...

Abstract

The invention relates to a method for breeding black barley, and belongs to the technical field of crop breeding. The method is special for the production of the black barley. The method comprises the following steps of: performing artificial crossing group mating by using two-rowed barley flower 30 as a female parent and using new black barley line 96717 as a male parent, performing secondary backcross by using an F1 generation plant as a female parent and using flower 30 as a transmigration male parent, and selecting individual black strains in backcross descendants to obtain black barley hybrid varieties. The bred strains have the characteristics of short stalks, lodging resistance, high yield, high thousand seed weight and the like. The bred strains are well shown in Jiangsu coastal regions, the thousand seed weight reaches over 42 grams, and the bred strains are suitable for the demands of processing barley kernels and barley meal and popularized and planted in the Jiangsu coastal regions.

Description

1. Technical field [0001] The invention relates to a method for breeding black barley and belongs to the technical field of crop breeding. It is used exclusively for the production of black barley. 2. Background technology [0002] With the improvement of people's living standards, people's demand for food is more and more diversified. Black barley food has been very popular in the market in recent years, and the price is twice that of yellow barley food. However, the variety of black barley used in production is "Obi". Its plant height is too high, it is not resistant to lodging, and its yield is low. Therefore, by breeding new varieties of black barley with high yield and resistance to lodging, people's demand for black barley food can be met. . 3. Contents of the invention [0003] 1. Technical issues [0004] The invention proposes a black barley breeding method aimed at the problems of low domestic black barley yield and low lodging resistance. The bred black barle...
