Abstract

The invention discloses a breeding method of a rice storing line with special characters, and belongs to the technical field of special rice breeding. The method comprises the following steps: selecting four special rice varieties respectively with glabrous property, premature senility resistance, endurable storage and yellow seed coat glutinous property, hybridizing and multi-crossing, screening the strains with glabrous property, premature senility resistance, endurable storage, yellow seed coat, glutinous property, agronomic character and yield character in segregative generation, breeding the yellow glutinous rice restoring line with the strains with glabrous property, premature senility resistance and endurable storage, assembling the yellow glutinous rice restoring line with the sterility line with the same characters to breed the glabrous, anti-premature senility and storage-endurable yellow glutinous hybrid rice. The hybrid rice is premature senility resistant, storage endurable, high in yield, easy for mechanically harvesting, the rice paddy is yellow, the rice is soft and good in taste and rich in various nutrients.

Description

technical field [0001] The invention specifically relates to a method for breeding rice restorer lines with special traits, and belongs to the technical field of special rice breeding. Background technique [0002] People call the common cultivated rice the type with chaff and leaves without hair, called naked rice. In order to meet the needs of mechanization, most of the rice varieties in the United States are naked rice. Because of their good rice quality and high light efficiency, they have been successfully used in conventional variety breeding in my country. "Bare body rice" is hairless all over the body, and it is difficult for pests to attach and invade. It has strong resistance to diseases and pests. It can reduce skin itching and damage to the skin during manual harvesting and threshing. It is easy to mechanized harvesting and processing. No dust, can reduce environmental pollution, so it is also called "environmental protection rice". Premature senescence of rice...
