Abstract
The invention provides a method for breeding disease-resistant rice variety. The method can easily and conveniently detect the disease resistance of rice varieties. According to the invention, during selection of a rice variety with disease susceptibility (an experimental material), experimental disease-susceptible rice (an experimental material) suffering from diseases for a few consecutive years is preferably used; uniform stirring should be carried out during mixing a disease-susceptible variety and brown sugar water, and fermentation time is strictly controlled; and during sprinkling of a fermented solution, weather conditions should be noted, and uniform sprinkling should be guaranteed.
Description
Technical field
The present invention exactly can allow select disease resisting rice kind more effectively, simple, practical easy to operate.There is different degrees of rice blast in a lot of rice paddy seeds now during establishing in large scale, causes the significantly underproduction, is so accomplished by selecting disease-resistant variety.
Background technology
Oryza sativa L. is one of China's staple food crop, has very big yield potential.Heilongjiang Province is one of China's main Rice Production ground, has Beijing University's storehouse good reputation, due to being affected by special geography and climate, more has strict requirements to the resistance of Oryza sativa L..So the present invention works out a kind of method of breeding rice Variety Disease-resistance, provide technology for rice breeding, be that increases in grain production contribute.
Content of the invention
Problem to be solved by this invention is exactly how just to select disease-resistant rice paddy seed, provides a kind of method of paddy disease-resistant breeding.Its purpose is exactly to solve complexity during breeding resistant variety for the breeding people, the time consuming nature and substantial amounts of resource of consuming.Simple and effective operational approach allows breeding people to hasten one's steps during breeding resistant variety.
The method of conventional herd breeding resistant rice cultivars be easily susceptible rice varieties with by selection-breeding rice varieties plantation together with, if being treated as disease-resistant variety by the Oryza sativa L. of selection-breeding is not susceptible, in fact this method is very low by the susceptible probability of the Oryza sativa L. of selection-breeding, if temperature, humidity are suitable during the fertility of Oryza sativa L., just the disease of the rice varieties of susceptible disease is also very light at last, institute is in this way inconspicuous in Breeding Process, there is certain error.And this method of my invention is that pressure is susceptible by the rice plant of selection-breeding, by experiment rice varieties, be there is certain disease resistance ability without susceptible turning out
Specific implementation method：
Material
Feel and have the bar rice plant alive of rice blast, brown sugar, water, Plastic Drum, small plastic canopy, micromill.
The first step：The bar rice plant alive that sense is had rice blast is pulverized.
Second step：Susceptible rice plant after pulverizing, brown sugar, water are pressed 0.25：0.5：25 obtain ratio is thoroughly mixed.
3rd step：The mixture having configured is poured into be put in plastic greenhouse in Plastic Drum, temperature is in 20 DEG C 32 DEG C of indirect fermentation 36 hours.
4th step：The positive and negative in the rice plant blade by selection-breeding is sprayed, the period that sprays is rice tillering latter stage to early stage of earing, whole cycle three times after cultured rice blast solution is filtered.
Claims (4)
1. a kind of method of breeding rice disease-resistant variety：
The first step：The bar rice plant alive that sense is had rice blast is pulverized.
2. second step：Susceptible rice plant after pulverizing, brown sugar, water are pressed 0.25：0.5：25 obtain ratio is thoroughly mixed.
3. the 3rd step：The mixture having configured is poured into be put in plastic greenhouse in Plastic Drum, temperature is in 20 DEG C 32 DEG C of indirect fermentation 36 hours.
4. the 4th step：The positive and negative in the rice plant blade by selection-breeding is sprayed, the period that sprays is rice tillering latter stage to early stage of earing, whole cycle three times after cultured rice blast solution is filtered.
