Method for breeding giant embryo glutinous rice

Abstract

The invention discloses giant embryo glutinous rice and a method for breeding the giant embryo glutinous rice. The method comprises the following steps of: selecting giant embryo mutation coarse rice grains or glutinous mutation coarse rice grains by naked eyes from coarse rice of glutinous rice or giant embryo rice M2 seeds by irradiating seeds of glutinous rice or giant embryo rice seeds which serve as a material by 60Co-gamma rays with a 380Gy dose according to the characteristic that the giant embryo character and glutinous character of rice are controlled by a single recessive gene, and the rice can be obtained by induced mutation or hybridization, and breeding to form giant embryo glutinous rice varieties by the selection of an agricultural technology and yield characters or selecting the coarse rice grains with the giant embryo character and the glutinous character by the naked eyes from F2 seed coarse rice by the hybridization of the glutinous rice and the giant embryo rice, and breeding to form glutinous rice varieties by the selection of an agricultural technology of 2 to 3 generations and the yield characters. By the method, the specific rice varieties which have the giant embryo character and the glutinous character simultaneously can be bred easily and quickly, and the coarse rice of the giant embryo glutinous rice is rich in special nutritional ingredients such as protein, fat, essential amino acid, dietary fibers, vitamins, gamma-aminobutyric acid and the like.

Description

technical field [0001] The invention specifically relates to a giant-embryo glutinous rice and a breeding method thereof, belonging to the field of special rice breeding. Background technique [0002] As one of the development trends of rice breeding in the 21st century, the breeding of rice with specific traits has attracted the attention of breeders from all over the world. The embryo of giant embryo rice is 2-3 times that of ordinary rice, rich in γ-aminobutyric acid, minerals, amino acids, vitamins and other natural nutrients and physiologically active substances. Glutinous rice also belongs to the special rice type. Glutinous rice is delicious and can be processed into many foods, and is loved by the majority of people. At present, all the giant embryo rice bred at home and abroad are ordinary giant embryo rice, and there are few reports on the breeding of giant embryo glutinous rice with the characteristics of giant embryo and glutinous rice. The purpose of the prese...
