Abstract

The invention discloses a breeding method of a bare giant embryo red glutinous rice variety, belonging to the technical field of special rice breeding. The breeding method is characterized in that bare rice, giant embryo rice, red rice and glutinous rice varieties are taken as parents, genes, which respectively control the properties of bare body, giant embryo, red seed coat and glutinousness, are polymerized together by a technical method of paired hybridization and then hybridization, and then target characters, agriculture and yield characters are selected for multiple generations to breed the special rice variety with the properties of bare body, giant embryo, red seed coat and glutinousness. According to the breeding method, the genes, which respectively control the properties of bare body, giant embryo, red seed coat and glutinousness, are polymerized together, and the target characters, the agriculture and the yield characters are selected for multiple generations to breed the bare giant embryo red glutinous rice variety with the advantages of bare rice, giant embryo rice, red rice and glutinous rice. The bare giant embryo red glutinous rice variety is more insect-resistant, is more easy to be mechanically harvested, has rich nutrients and functional components, and has a better health care function. The breeding method provided by the invention is simple, and is high in breeding efficiency and good in benefit.

Description

technical field [0001] The invention specifically relates to a breeding method for a red glutinous rice variety with naked giant embryos, and belongs to the technical field of special rice breeding. Background technique [0002] "Naked body rice" is a rice that is hairless all over the body. Because it is not easy for pests to attach and invade, it has strong resistance to pests and diseases. It can reduce skin itching and damage to the skin during manual harvesting and threshing, and is easy to harvest by mechanization. , no dust during processing, can reduce environmental pollution, so it is also called "environmental protection rice". Giant embryo rice is rich in γ-aminobutyric acid, minerals, amino acids, vitamins and other natural nutrients and physiologically active substances. Red rice is rich in many nutrients, especially iron, which has the effect of nourishing blood and preventing anemia. It is also rich in phosphorus, vitamin A and B complex, which can improve ma...
