Abstract
The invention relates to a method for plant breeding and belongs to the field of genetic breeding. With the improvement of the living standards of people, adjustment of the planting structure and fierce competition in international markets, the problem of how to breed high-yield conventional japonica rice varieties which are high in disease resistance performance and high in taste quality is urgent to be solved. By the method for breeding new rice varieties through irradiation, defects in the prior art can be overcome, and the new rice varieties which are high in quality (high in both exterior quality and taste quality), high in yield and high in disease resistance can be bred in a short time.
Description
Technical field
The present invention relates to the breeding method of a Plants, more specifically to a kind of breeding method by Irradiate breeding high-quality, high yield, disease resisting rice new varieties.
Background technology
Paddy rice is the first crop of China, and the paddy rice of China's cultivation mainly contains two subspecies, i.e. Xian subspecies and round-grained rice subspecies.The Jiangsu Main Cultivation be the round-grained rice subspecies, account for more than 90% of Jiangsu Monitoring of Paddy Rice Plant Area.SOYBEAN IN HIGH-YIELD BREEDING is the important goal of rice breeding always, and China is because populous, and arable area reduces year by year, and the pressure of grain demand strengthens, and SOYBEAN IN HIGH-YIELD BREEDING is put in the first place for a long time always, and the Upgrading of rice quality lags behind.In recent years, along with the raising of people's living standard, the adjustment of pattern of farming and the pressure of competition in the international market, and the impact of factor such as take place frequently of various natural calamity, the quality-improving of paddy rice is more aobvious important.The existing preferably disease-resistant performance of quick breeding how, the high yield conventional japonica rice kind that has again the high-quality food flavor has become rice breeding problem in the urgent need to address.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art and problem by another kind of approach, a kind of breeding method by the Irradiate breeding new rice variety is provided, thereby cultivate at short notice high-quality (existing good exterior quality have again good Cooking Quality), high yield, disease-resistant new rice variety, make it obtain large scale application.
The applicant is through for many years repetition test, in many hybridization schemes and selection, find, radiation breeding also can reach goal of the invention well rapidly to solve the problem of prior art, and a kind of method by the Irradiate breeding new rice variety of the present invention may further comprise the steps:
