With the support of provincial breeding research, Sichuan crop breeding research resistance identification team has won the first prize of national science and Technology Progress Award in 2012 after years of continuous collaborative innovation, which is the first national science and technology progress award of plant protection discipline in Sichuan Province The team has successively put forward the first set of physiological race identification hosts with clear genetic background of resistance to rice blast in China, which has contributed to the cause of resistance loss of Qingshui rice to rice blast; the first detection of the pathogenic type of wheat stripe rust pathogen "Gui Nong 22" from the summer area of the pathogen has laid a foundation for effective control; the selected resources of resistance to rice borer have laid a foundation for rice breeding and rice breeding Production will have an important impact; resistance genes or QTLs were studied, and 30 resistance genes of resistant materials were preliminarily identified, and a new allele was found Last year, the team identified more than 50000 breeding materials or lines for major crop diseases and insect pests, such as rice blast, stripe rust, and rice planthopper, and found that 29 out of more than 500 approved varieties had lost or declined resistance to major crop diseases and insect pests.
