不同水稻品种抗灰飞虱评价及抗性机制研究

Study on Evaluation of Different Rice Varieties Resistance to the Small Brown Planthopper and Resistance Mechanism

水稻对飞虱的抗性主要表现在排驱性、抗生性和耐害性3个方面。通过对不同水稻品种3个抗性方面的研究,鉴定了高抗和中抗水稻品种,为以后开展抗稻灰飞虱种质资源的筛选提供了参考。

Resistance to the rice small brown planthopper showed in three aspects including expulsion resistance,antibiosis and resistance to harm nature. Through the study on these three aspects of different rice varieties research ,high resistance and medium resistance rice varieties were identified so as to provide the reference for the screening of germplasm resources.
