Embodiment Construction
[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0036] In order to be closer to the natural identification environment, and more efficient and true to respond to variety resistance, the present invention responds to the resistance identification method of rice panicle blast by inoculating induced varieties and mainly includes the following steps: (1) collection, isolation and preservation of bacterial strains; (2) Selection and cultivation of bacterial strains; (3) Selection of induced varieties; (4) Selection of disease nurseries for natural identification; (5) Sowing, seedling raising and transplanting of rice varieties to be identified and induced varieties; (6) Strain inoculation ; (7) Disease investigation and eval...

The present invention discloses a method for identifying and evaluating paddy rice neck blast resistance. Induced varieties in a staggered growth period are utilized, a plurality of monospora strainsare inoculated alone, field strains in a disease nursery are combined, richness of the field strains is enriched, at the same time, spore release duration is increased, so that paddy rice varieties inthe growth period are full have sufficient and abundant spore concentration at an onset of neck blast in a whole head sprouting mature period, and the paddy rice varieties in each different growth periods can be seeded and identified at the same time. At the same time, the method overcomes problems that direct injection variety methods are too heavy in onset, onset effects caused by natural onsetmethods are unstable, etc. The method can be effectively used as an identifying means for the paddy rice neck blast resistance and provides reliable solutions. For paddy rice parent resistance screening, paddy rice resistance breeding, paddy rice resistance resource screening, etc.
Description
technical field [0001] The invention relates to a rice disease identification method, more specifically, to a method for identification and evaluation of rice panicle blast resistance. Background technique [0002] As the main food crop, rice suffers huge losses due to pests and diseases every year. Rice blast is a fungal disease caused by the rice blast fungus Magnaporthe oryzae (clonal generation: Pyricularia oryzae), which is widely distributed all over the world and seriously endangers the production safety of rice, wheat and other food crops. With the gradual increase of population and the gradual reduction of arable land, the increase of grain production is facing enormous pressure. Rice blast is an important bottleneck that threatens the safety of rice production. The occurrence of rice blast often leads to a substantial reduction in rice yield. In 1980, more than 50% of the yield loss in Zhejiang Province was caused by rice blast; in 1981, early rice blast in sout...
