1979～1986年以来,进行了水稻品种抗褐稻虱鉴定及抗性基础理论研究。 一、1979年以来,先后对省内外稻资源,杂交稻组合和三系以及常规稻稳定品系累计5326份,进行了抗褐稻虱鉴定(其中省内历年保存的稻种资源已全部鉴定完毕),从中筛选出具有中抗以上水平材料达220余份,可供生产和育种部门使用,其中签定的“晚籼83-12”新品系1986年全省推广面积达十四万余亩。 二、在进行抗性鉴定的同时,为了合理利用抗原,减少抗性育种的盲目性,为此,对品种抗虫性和抗性育种有关基础理论进行了探讨。
From 1979 to 1986, the identification of rice varieties against brown planthopper and the basic theory of resistance were carried out. First, since 1979, a total of 5326 samples of rice resources, hybrid rice combinations and three lines of conventional rice and stable strains of rice have been accumulated in and out of the province, and the identification of brown planthoppers against brown planthoppers has been carried out (among which, the resources of rice varieties preserved in the province over the years have all been identified) , From which screening more than 220 copies of the material above the level of resistance, for the production and breeding departments, which signed the “late indica 83-12” new line in 1986 to promote the province’s area of more than 140,000 acres. In the meantime, in order to rationally utilize the antigen and reduce the blindness of resistance breeding, this paper discussed the basic theory of insect resistance and resistant breeding.
