A kind of rice variety breeding method with yellow glume and purple black seed coat

Abstract

The invention discloses a rice variety breeding method with yellow glume and purple-black seed coat, belonging to the technical field of crop breeding. In the present invention, Yanzi No. 1 is used as the female parent, and the glume and seed coat are both purple-black, and Wuyujing No. 3 (the glume color is yellow, and the seed coat is white) is used as the male parent, and the hybrid F 1 The rice grains of the generation show purple-black glumes, purple-black seed coats, F 2 The purple-black glumes and yellow glumes were separated, the purple-black seed coats were not separated from the white seed coats, and the inheritance to F was delayed. 3 Separation occurs only in generation, so only in F 2 Individual plants with yellow glume and purple-black seed coat traits were screened in the population, and continuously selfed to F 7 The traits of the new generation are stable, and the bred line has excellent characteristics such as high yield, good rice quality, and strong lodging resistance. Aiming at the current shortcomings of purple rice such as low yield per unit area, poor taste, and inability to meet market demand, this strain can be specially used in the production of purple-black rice and food processing.

Description

technical field [0001] The invention belongs to the technical field of rice breeding, and in particular relates to a rice variety breeding method with yellow glume and purple-black seed coat. Background technique [0002] Colored rice is rice that emphasizes that its functional components can fully display the body's defense function, regulate circadian rhythm, prevent disease and promote recovery. Purple rice is an important colored rice. It presents a purple-black color. Studies have found that anthocyanins belong to flavonoids, which have natural antioxidant capacity and can delay the aging of the human body and repair the body, making purple rice a hot research area. [0003] Compared with white rice, purple rice not only contains richer anthocyanins, but also contains essential amino acids, cellulose, calcium, iron, zinc and other trace elements, as well as phytic acid, isovitexin, γ-oryzanol , sterols, octacosanol, squalene, GABA, vitamin E and more than 100 active su...

AI Technical Summary

Problems solved by technology

[0006] The invention is a method for breeding rice varieties with purple-black seed coats with yellow glumes and purple-black seed coats aimed at the problems of low yield per unit area and low lodging resistance of domestic purple-black rice. The purple-black rice varieties bred have high yield and low lodging resistance. Strong resistance, good rice quality and other characteristics, can meet the market's processing demand for purple rice
