摘要
本研究采用倒苗继代接种的实验模拟方法，研究了病菌和寄主群体互作中的定向选择和稳定性选择作用，并以此为依据初步探讨了品种抗瘟性“丧失”预测方法的设想，为抗瘟性水稻品种的合理搭配利用提供科学依据，旨在维持自然界病菌群体的相对稳定，延长抗瘟品种的使用寿命，持续控制稻瘟病灾变。
Studied on the directional selection and
stabilizing selection from the interaction between rice varieties and blast fungus colony by
reinoculated the rice varieties from generation to generation.The possibility were evaluated that
the selection action use for forcasting varieties resistance break down.The results can provide
scientific basis for the utilization of the resistant varieties and prolonged the utilization period
of resistant varieties.The paper were discussed the method of keep relative stabilize of race
colony of Pyricularia grisea in natural and continued control the calamity caused by rice blast
fungus.
