STUDY ON THE GENETIC IMPROVEMENT OF CROP DISEASE RESISTANCE
ABSTRACT
In this study, the genetic improvement of crop disease resistance was comprehensively explored. Firstly, the research background and significance are introduced, as well as the current research status at home and abroad. Secondly, the theoretical basis of the genetic improvement of crop disease resistance, including the concept and classification of disease resistance, genetic basis and molecular mechanisms, as well as the methods and techniques of genetic improvement. Then, the application of traditional breeding methods, molecular marker-assisted breeding methods and genetic engineering techniques in the genetic improvement of crop disease resistance are introduced in detail. Finally, the effectiveness and feasibility of these techniques in improving disease resistance were demonstrated on the major crops such as wheat, rice and maize.
