Introduction
GB/T 45211 "Technical Procedures for Evaluation of Wheat Disease and Insect Resistance" aims to standardize the technical methods, operating procedures and identification of wheat disease and insect resistance.
Evaluation principles provide standardized technical methods for breeding material screening, hybrid offspring selection, disease resistance gene discovery and variety evaluation and approval.
The method plays an important role in guiding and promoting disease-resistant breeding, variety layout and plant quarantine of wheat in my country.
GB/T 45211 is divided into the following 8 parts.
--- Part 1.Stripe rust;
--- Part 2.Leaf rust;
--- Part 3.Stem rust;
--- Part 4.Fusarium fusarium;
--- Part 5.Sheath blight;
--- Part 6.Yellow dwarf disease;
--- Part 7.Aphids;
--- Part 8.Midges.

3.1
wheat sharpeyespot
3.2
disease resistance
A heritable trait in plants that can reduce or overcome the pathogenic effects of pathogens.
3.3
The process of identifying the host plant's response degree and resistance level to specific pests and diseases through appropriate technical methods and standards.
3.4
Pathogenicity
The ability of pathogens to interfere with host growth and cause disease.
3.5
The process of placing the pathogen inoculum into the diseased part of the plant through artificial operation under suitable conditions and causing the disease to occur.
3.6
