Excellent flavour rice breeding method

Abstract

The invention relates to a breeding method of rice with good taste, which belongs to the rice hereditary improvement and biotechnology application field. Wuxiangjing14 of the Jiangsu high-yielding non glutinous rice variety is hybridized with Guandong 194 of the high quality non glutinous rice variety to fit a group; F4 begins to select an individual plant; F5 begins to perform molecule labeling auxiliary selection, a good taste variety Nanjing 46 with stable and consistent economical character is obtained, and the mutant gene type of the dark endosperm thereof is Wx-mqWx-mq. The rice variety of the Nanjing 46 carrying the mutant gene locus is breeded, the appearance of the endosperm is nebulous and milk-white, has a little worse transparence, runny rice quality, and transparent and bright surface, synthesizes the flexibility of sticky rice and the elasticity of rice, the cold rice is not hard, the taste and the quality are very good. The breeding method of rice with good taste has wide application prospect in the areas where the late round-grain nonglutinous rice is planted, such as Jiangsu, Shanghai, and Zhejiang, etc.

Description

technical field [0001] The invention relates to a method for cultivating good-tasting rice, which belongs to the field of rice genetic improvement and biotechnology application. Background technique [0002] As one of the important goals of rice breeding, rice quality has attracted more and more attention from breeders and consumers. Since 2000, the goal of japonica rice breeding in Jiangsu Province has shifted from high yield, high quality, and multiple resistance to high quality, high yield, and multiple resistance, and high quality has become the primary goal of japonica rice breeding in Jiangsu Province. Therefore, all breeding units attach great importance to the improvement of rice quality, pay attention to the selection of high-quality materials as parents of cross breeding, and strengthen the screening and identification of rice quality in the segregation generation, and have made remarkable achievements. From 2000 to 2008, the number of new varieties (combinations)...

AI Technical Summary

Problems solved by technology

In particular, the poor taste quality and the lack of high-quality varieties that are competitive in the international market have become a major factor restricting the development of high-quality japonica rice industry in our province.
