Abstract:

The project of crop and livestock breeding in Sichuan Province has set up a special project for identification of crop disease and insect resistance since the "Eighth Five-Year Plan", which has supported seven five-year plans continuously, and provided stable support and conditional basis for carrying out the research work of crop disease and insect resistance in the whole province. The project team has carried out researches on four topics: identification technology of disease and pest resistance of main crops, monitoring of resistance of crop production varieties and virulence variation of pathogens, creation and screening of crop resistance sources, and evaluation of resistance of crop breeding materials. A series of research results have been achieved in crop disease and pest resistance research, creation and screening of resistance sources, and public services for resistance evaluation. This paper introduced the main progress of crop disease and pest resistance research at home and abroad and in Sichuan Province in terms of identification technology, resistance source materials, disease and pest monitoring, etc. This article also analyzed the internal logical connection of each thematic research in the systematic research of crop disease and pest resistance, and sorted out the problems existing in the current research process, and prospected the development trend of crop disease and pest resistance research, in order to provide reference for crop disease and pest resistance research.

Key words: crops, disease and insect resistance, resource identification, gene mining and polymerization, application of intelligent technology
