Problems solved by technology

However, the varieties reported so far are all rich in 1-2 kinds of functional components, rice varieties rich in multiple functional components are relatively rare, especially rich in resistant starch, cellulose and vitamin A at the same time, and low in water-soluble protein content There are no reports on the functional special rice varieties that have the functions of lowering blood sugar, blood fat and weight loss, and are suitable for kidney disease and diabetes patients

Abstract

The invention particularly relates to a breeding method for a multifunctional rice variety, belonging to the technical field of special rice breeding. The method comprises the following steps: selecting four rice varieties with high resistant starch content, low water-soluble protein content, high cellulose content and high vitamin A content as materials, and performing hybrid and multi-cross polymerization; measuring and screening the agronomic trait, yield trait, resistant starch content, water-soluble protein content, cellulose content, vitamin A content and the like of a segregative generation to breed the multifunctional rice variety with excellent agronomic trait and yield trait, high resistant starch content, high cellulose content, high vitamin A content and low water-soluble protein content. Rice produced by using the variety has the health functions of reducing blood sugar and blood fat and losing weight, is suitable for taking by patients with kidney diseases and diabetes, and has a very good nutritional health function on the type of patients.

Description

technical field [0001] The invention specifically relates to a method for breeding multifunctional rice varieties, and belongs to the technical field of special rice breeding. Background technique [0002] In recent years, the nutritional and health functions of rice have attracted more and more attention from consumers. Some special rices are favored by consumers because of their unique health effects on the human body. The sweet rice hwachengbyeo su-1 and hwachengbyeo su-2 bred by Korean breeders have a total sugar content as high as 5%-9%. The special rice variety high-fiber rice "Shuiyuan 464" has been successfully bred by genetic mutation, and the dietary fiber of brown rice and polished rice The contents were 2-fold and 3-fold higher than the control, respectively. The International Rice Institute has bred an iron-rich high-yielding rice variety IR164 with an iron content of more than 25 mg / kg. Yushan County Special Rice Research and Development Center bred the vitam...
