Problems solved by technology

[0004] Technical Problem The purpose of this invention is to provide a method for breeding special rice varieties for people with kidney disease and diabetes, so as to cultivate a new variety of functional health-care rice with an output equivalent to the current high-quality varieties and an absorbable water-soluble protein content below 4%. , to solve the problem that there is no rice with low water-soluble protein in our country, so that people with kidney disease and diabetes with renal dysfunction can have edible special rice

Embodiment Construction

[0025] 1. Using the mutant variety LGC-1 with low water-soluble protein introduced from the radiation breeding field of the Japan Institute of Bioresources as the female parent, using Amazing Waxy as the male parent, hybridization, self-crossing of hybrid offspring, starting from F1, the total protein of offspring seeds Sodium dodecylsulfonate denaturation-polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed that low gluten and high gliadin traits always appear together; F 1 The seeds all showed the characteristics of low gluten content and high prolamin content ( figure 2 ); F 2 The ratio of low gluten and normal protein traits in seeds is about 3:1 ( image 3 ); Determination of F 3 Seed protein, its low gluten homozygous, heterozygous and normal segregation ratios conform to F 2 Plant genotype 1:2:1 ( Figure 4 ). It shows that the traits of low gluten and high gliadin are controlled by single dominant gene ( image 3 ), and can be stably passed on to offspr...

Abstract

The present invention is development of special rice variety for nephrosis and diabetes patients and belongs to the development of new rice variety. Through the analysis of rice in storage protein content, protein coponents, SDS-PAGE, SSR mark, etc., the molecular mark selection, the measurement of SDS-PAGE, protein content, etc., new rice variety W3660 with water soluble protein content less than 4% is developed.

Description

1. Technical field [0001] The invention relates to a breeding method of special rice varieties for people with kidney diseases and diabetes, which belongs to the breeding method of new rice varieties with low water-soluble protein, and is specially used for breeding rice varieties suitable for people with kidney diseases and diabetes. 2. Technical Background [0002] In recent years, due to changes in the living habits and ecological environment of urban and rural residents in my country, the number of patients with kidney disease and diabetes in China has been increasing. According to statistics, the total number of diabetic patients in China has exceeded 100 million in recent years, of which nearly 6 million are due to diabetes He was hospitalized for kidney disease. Patients with kidney disease and diabetes (combined with kidney disease) have protein metabolism dysfunction. During the treatment period, rice with an absorbable protein content of more than 4% cannot be eaten...
