AI Technical Summary

Technical Problem

Existing technologies suffer from a lack of germplasm resources for wheat scab and stem rot, and screening methods are inefficient and have poor reproducibility, making it difficult to quickly and accurately screen wheat germplasm resistant to both diseases.

Method used

Mutation breeding technology combined with a two-stage disease inoculation screening strategy was adopted. First, FHB ear resistance was screened, and then CR resistance was screened. Standardized preparation of infected soil, pathogen propagation and inoculation procedures were used, combined with clear identification indicators such as the incidence level of stem base rot and the spikelet rate of Fusarium head blight, to achieve joint screening of the two diseases.

Benefits of technology

This method allows for the rapid and precise screening of new wheat germplasm with high resistance to both diseases, shortening the breeding cycle, improving the repeatability and reliability of screening results, and obtaining new germplasm with significantly better resistance than the original parents, making it suitable for wheat breeding and research.

Abstract

The application discloses a kind of evaluation and screening of both fusarium head blight and foot blight germplasm and its application, belong to crop breeding and plant pathology technical field.The method includes: preparation contains false fusarium graminearum and fusarium graminearum soil matrix with bacteria;Selecting wheat population, after seed soaking, spring, sowing, transplanting, first in the soil with bacteria Identification stem base rot resistance, again in the wheat flowering stage using double flower drip method inoculation fusarium head blight, identify disease spikelet rate and wilting rate;Screening PSS≤0.2 and stem base rot disease incidence grade≤1.2 as target compatible germplasm.The application innovatively uses "two-stage, double-disease joint screening" strategy, standardized process ensures that screening result is stable and reliable, greatly shorten the breeding cycle, and the compatible germplasm screened can be directly applied to wheat breeding, and the special type strain can be used for resistance mechanism research, which has important significance for guaranteeing wheat production safety, improving quality and reducing pesticide use.
