Giant embryo black kerneled rice and method for breeding giant embryo black kerneled rice

Abstract

The invention discloses giant embryo black kerneled rice and a method for breeding the giant embryo black kerneled rice. The method comprises the following steps of: selecting giant embryo mutation coarse rice grains by naked eyes from coarse rice of black kerneled rice M2 seeds by irradiating the black kerneled rice seeds which serve as a material by 60Co-gamma rays with a 380Gy dose according to the characteristic that the giant embryo character of rice is controlled by a single recessive gene, and the rice can be obtained by induced mutation, and breeding to form giant embryo black kerneled rice varieties by the selection of an agricultural technology and yield characters. By the method, the specific rice varieties which have the giant embryo character and a black seed coat character simultaneously can be bred simply and quickly, and the coarse rice of the giant embryo black kerneled rice is rich in special nutritional ingredients such as protein, fat, essential amino acid, anthocyanin, carotene, cardiac glycoside, dietary fibers, vitamins, gamma-aminobutyric acid and the like.

Description

technical field [0001] The invention specifically relates to a high-efficiency breeding method for a special rice variety containing both giant embryo and black seed coat traits, and belongs to the field of special rice breeding. Background technique [0002] Giant embryo rice is a kind of rice with huge embryo. The nutritional value of rice is greatly improved due to the enlargement of embryo, and it has unique and potential economic use value. Giant embryo rice is rich in γ-aminobutyric acid, protein, various minerals, amino acids, vitamins and other natural nutrients and physiologically active substances. Regular consumption can improve health and regulate human circadian rhythms. Black rice is also a type of high-nutrition special rice. Black rice is rich in anthocyanins, carotene and cardiac glycosides. It combines natural color, aroma, taste and nutritional effects. It is known as medicinal rice and blood-enriching rice. , loved by the general public. Yet domestic an...
