Problems solved by technology

The number of black rice varieties bred is small, and the production is mainly some traditional local old varieties that have been used. Most of them are conventional black rice with a long service life. The species degenerates, the yield is low, and the production efficiency is poor
However, hybrid black rice with excellent comprehensive traits such as high yield, high quality, stable yield, and wide suitability is in short supply, especially the hybrid black rice with high yield, high quality, and full fragrance has not been reported so far.
Due to the lag of black rice breeding work, the development of black rice production is seriously restricted, and it cannot meet the urgent needs of consumers for high-quality black rice

Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention.

[0025] A method for cultivating a new variety of full-flavor high-quality and high-yield hybrid black rice, comprising the following steps:

[0026] A. Cultivation of fragrant high-quality black rice CMS line Heixiang 1A:

[0027] a1. Cultivation approach: adopt the three-line method to cultivate the BT-type nucleoplasmic interaction japonica black male sterile line;

[0028] a2. Parental selection: the parental source of Heixiang 1A is: [Wuyunjing 7A / (Ewan 17 / / Ewan 17 / Xiaogan Heijing)];

[0029] a3. Hybridization method: First, use Ewan 17 as the female parent, single cross with Xiaogan Heijing as the male parent to obtain F1, then use the above-mentioned F1 as the male parent, and use Ewan 17 ...

Abstract

The invention relates to the technical field of rice breeding and in particular discloses a method for breeding a novel full-fragrance type high-quality high-yield hybridization black rice variety. The method comprises the following steps: A, breeding a fragrant high-quality black rice sterile line Heixiang 1A; B, breeding a fragrant high-quality round-grained nonglutinous rice restorer line Xianghui 78; C, breeding a novel full-fragrance type high-quality high-yield hybridization black rice variety Heixiangyou 178. The method has the characteristics that varieties with high quality and good resistance are adopted as parents, the quality and the resistance of hybridization generations can be improved, correct hybridization and rehybridization methods are used, and the polymerization frequency of beneficial properties can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of rice breeding, in particular to a method for cultivating a whole-fragrant high-quality, high-yield new hybrid black rice variety. Background technique [0002] Black rice is a type of rice in which the seed coat and aleurone layer contain a special natural dark black substance-"rice melanin" (ie anthocyanin), and brown rice is black. According to literature records, black rice is an ancient and valuable rice species in my country. The rice made of black rice has a combination of color, fragrance, taste, nutrition and health care. It is called "blood-enriching rice" and "medicine rice" among the people. , "Longevity Rice", has the laudatory title of "King in Rice". According to modern research data, black rice is rich in black matter, which makes the nutritional and health value of black rice higher than that of white rice. [0003] Black rice is not the staple food rice of our people. Black rice is mainl...
