Abstract

The invention relates to a breeding method for breeding rice variety resistant to rice panicle blast in Jiangsu province, belonging to the field of rice genetic improvement and biological technology application. The breeding method comprises the following steps of: selecting Huai rice variety (containing Pi-ta genes) which is moderately susceptible to rice panicle blast and Nanjing 38 (containing Pi-b genes) which is susceptible to rice panicle blast to prepare a hybrid group; harvesting single strains of F1 generation, F2 generation and F3 generation in a mixing manner, carrying out molecular marker-assisted selection on rice panicle blast-resistant genes Pi-ta and Pi-b from the F4 generation, and polymerizing two resistance genes to obtain a double-gene homozygote with the gene type of Pi-taPi-taPi-bPi-b; and after yield and agronomic trait selection of subsequent generations, breeding a new high-yield rice strain which is stable and consistent in agronomic trait and resistant to rice panicle blast in Jiangsu province till the F6 generation. The breeding method disclosed by the invention not only can be used for rapidly breeding the new rice variety which is resistant to the rice panicle blast, but also is free of a large amount of inoculation and identification, thereby saving the breeding cost.

Description

A kind of breeding method of cultivating anti-Jiangsu Province panicle blast rice varieties
One, technical field
The present invention relates to a kind of breeding method of cultivating anti-Jiangsu Province panicle blast rice varieties, belong to rice genetic improvement and biological technology application.
Two, background technology
Rice blast is by Pyricularia oryzae (Magnaporthe oryzae; No condition: one of destructive disease of tool on the paddy rice that Pyriculariaoryzae) causes is commonly called as paddy rice " cancer ".All can receive infecting of rice blast pathogen in the paddy rice whole growing process, can be divided into: seedling pest, leaf pest, pulvinus pest, joint pest, panicle blast, grain pest etc. according to the position difference that infects.Wherein the harm of panicle blast is greater than leaf pest and other harm, can cause when serious that No kernels or seeds are gathered, as in a year of scarcity.Rice blast has the countries and regions of paddy rice plantation that generation is all arranged in 85 in the whole world.According to statistics, 1975~1990 years 16 in the period of, the global paddy rice production loss that is caused by rice blast is up to 1.57 hundred million tons.China is every at a distance from 7-10 once fairly large rice blast harm just to take place, and injured area reaches 300-600 ten thousand hm2, ten thousand tons of paddy loss 70-125.Paddy rice is the first cereal crops in Jiangsu Province, and unit yield ranks first in the whole country, and its intermediate keng rice area accounts for more than 80% of rice area.Rice blast also is the main rice disease in Jiangsu Province, and in early 1990s, onset area reaches 166. 67 ten thousand hm2,350,000 tons of the underproduction, and seedling, leaf, panicle blast all have generation, but the potential threat of panicle blast is maximum.Therefore Jiangsu Province reaches 4 grades the direct elimination system of taking to panicle blast in japonica rice new varieties authorization process.
The control of rice blast is mainly controlled disease through chemical control and plantation resistant variety, facts have proved, seed selection with promote the blast resisting kind be address this problem the most effectively, the method for safety and environmental protection.Excavate anti-source and identify that resistant gene is the basis and the prerequisite of cultivating disease-resistant variety.From different disease-resistant varieties, identify about 80 rice blast resistance genes at present, Pi-b, Pi-ta, Pi-d2, Pi9, Pi-21Cloned Deng at least 20 blast resistant genes.But except Pb1The research of outer these rice blast resistance genes all concentrates on the resistance of seedling pest, leaf pest, can not clear and definite its resistance to panicle blast.Selecting the disease-resistant gene of panicle blast is the prerequisite of panicle blast resistive breeding.
We utilize rice blast resistance gene Pi-ta, Pi-bFunctional label to Jiangsu Province over the years the japonica rice variety promoted of large tracts of land carry out genotype detection, ins conjunction with panicle blast resistance result, tentatively clear and definite through association analysis Pi-ta, Pi-bJoint effect has resistance preferably to Jiangsu Province's japonica rice rice blast especially panicle blast.The evaluation of resistance is the basis in the rice blast resistance breeding, and authentication method mainly contains the artificial infection evaluation and the lesion spontaneous induction is identified.The evaluation of tradition rice anti-rice blast germ plasm resource mainly is the land for growing field crops mist measuring, and this method required time is longer, needs to consume wide variety of materials, and receives such environmental effects bigger.Compare with field identification method, inoculation identifies and can carry out in early days at plant strain growth that not influenced by extraneous climatic factor, it is little to take up room.But in the resistance of kind is identified, also have many problems, like authentication method, evaluation criterion disunity, authentication method is nonstandard, lack of standardization, identifies that efficient is low, and condition is difficult to control etc. in the evaluation, thereby makes the qualification result that draws inaccurate, is difficult to unified
Standard is judged measurement, and then has influenced breeding for disease resistance work.Utilizing gene function marker assisted selection technology is to select according to the genotype that the difference of the sequence of disease-resistant gene design primer own carries out, and utilizes this method to carry out panicle blast resistive breeding work and not only selects accurately, and do not receive time and environmental limitations.Therefore, a kind of efficient transformation of invention and the breeding method of identifying the panicle blast resistant gene in Jiangsu Province's japonica rice panicle blast resistive breeding process, polymerization high yield, many disease-resistant genes are aims of the present invention in one.
Three, summary of the invention
Technical problem:The present invention relates to a kind of breeding method of cultivating anti-Jiangsu Province panicle blast rice varieties; The breeding method that adopts efficient transformation and resistant gene polymerization to select; In one, reducing the breeding cost, shortening breeding cycle is aim of the present invention with high yield, disease-resistant gene polymerization.
