在与农作物病虫害作斗争中,人们都十分重视抗性育种问题,尤其是在培育作物的抗病性方面,科学家花费了很大的精力,培育出了形形色色的各类农作物抗病性强的品种,如水稻的抗稻瘟病品种、番茄的抗黄化曲叶病毒病品种等,为农业优质高产立下了汗马功劳。目前,选育和利用具有遗传抗病性的品种,是防治农作物病害最经济而有效的措施。科技人员早就观察到,在易感病的品种中并非全部植株都发病,总能找到个别抵抗
In the fight against crop pests and diseases, people attach great importance to the issue of resistant breeding. Especially in cultivating the disease resistance of crops, scientists have devoted a great deal of energy to cultivating various types of crops with high disease resistance , Such as rice blast resistant varieties, tomato yellow curly leaf curl virus varieties, etc., for the agricultural high yield of high quality made a contribution. At present, the breeding and utilization of cultivars with genetic disease resistance are the most economical and effective measures to prevent crop diseases. It has long been observed by scientists that not all plants are susceptible to susceptible disease, and individual resistance can always be found
