Abstract

The invention relates to a breeding method of a japonica rice variety capable of controlling postprandial blood sugar of diabetes patients and belongs to the field of breeding of a new variety of rice. A japonica rice variety 'sugar-optimized rice No.1', in which content of resistant starch is higher than 10%, is bred in a manner of employing chalky rate, the content of amylose and the content of the resistant stratch and combining with methods such as molecular marker-assisted selection and the like. Yield of the 'sugar-optimized rice No.1' is higher than that of a 08JD26 strain and is 405 kg / mu. The invention belongs to the breeding method of a japonica rice variety in which the resistant starch is high in content. The method is used for breeding of the japonica rice variety which is suitable for the diabetes patients.

Description

technical field

[0001] The invention relates to the technical field of rice breeding, in particular to a method for breeding japonica rice varieties for controlling postprandial blood sugar in diabetics. Background technique

[0002] In the past 20 years, with the development of social economy and the increase and aging of the population, the incidence of diabetes has risen rapidly, and it is becoming younger, and it has gradually become a chronic non-communicable disease that is prevalent in the world. At present, the number of diabetic patients in my country has exceeded 92 million, and the incidence rate is rising rapidly at 9.9% per year, and it is showing a younger trend, ranking first in the world, while the annual direct medical expenses for the treatment of type 2 diabetes and its complications have reached More than 18.75 billion yuan has caused serious economic burden and social pressure.

[0003] Resistant starch belongs to polysaccharides and has no energy. It ca...
