摘　　要：The paper reports the study on resistance in 6 newly-bred rice varieties, such as Nongxiang 16 and 9234, to the whitehacked planthopper, Sogatella furcifera. In crossing with the susceptible Taichung Native 1 (TN1), the resistance of their F1 and F2 populations and the back-crossed BC1F1 populations have been evaluated. The resistance to 5. furcifera in Zhenongda 6022, 9234 and Zhongjian 96-3 was controlled by a single dominant gene, and by a single recessive gene in Nongxiang 16, R40 and Shuhui 881, respectively. These varieties possessed good agronomical characteristics and could be used in further rice breeding and rice production.The paper reports the study on resistance in 6 newly-bred rice varieties, such as Nongxiang 16 and 9234, to the whitehacked planthopper, Sogatella furcifera.
