Breeding method of high-yield early-matured soft rice

Abstract

The invention relates to a crop breeding method, and in particular relates to a breeding method of high-yield early-matured soft rice, which belongs to the technical field of plant cultivation. According to the breeding method, Japan high-quality soft rice, Rouxiaoding is taken as a female parent, Wuyungeng #27 with high quality, high yield, early maturing property and high disease resistance is taken as a male parent, and the female parent and the male parent are hybridized; by five-generation selection and resistance identification, a new species of soft rice with compact strain, high growth capacity, high yield and high lodging resistance is bred. The breeding method has the beneficial effects that the maturing time is short, the taste is good, the comprehensive resistance is high, the production stability is high, and the market prospect is good.

Description

technical field

[0001] The invention relates to a method for breeding crops, in particular to a method for breeding high-yield early-maturing soft rice, and belongs to the technical field of plant breeding. Background technique

[0002] Rice is the largest crop in my country. There are two main subspecies of rice cultivated at present, namely indica subspecies and japonica subspecies. Japonica rice varieties are indispensable for daily life and industrial production. In recent years, with the improvement of people's living standards, the adjustment of planting structure and the pressure of international market competition, the improvement of rice resistance and quality has become more and more important.

[0003] Soft rice is a kind of indica high-quality rice whose rice quality is between waxy and sticky. The rice is soft, sweet and refreshing, and will not harden or regenerate after being cold, so it is suitable for eating hot or cold. Most of the existing soft rice var...
