Studies on the resistance of the cross lines and some varieties of rice to three hoppers at IRRI in Philippines


, : Studies on the resistance of the cross lines and some varieties of rice to three hoppers at IRRI in Philippines. Korean Journal of Plant Protection 10(2): 121-125

The author gives details of investigations that he carried out while at the International Rice Research Institute in the Philippines for a short period in 1971 to study methods for the evaluation of varietal resistance in rice to attack by Nilaparvata lugens (Stal)) Sogatella (Sogata) furcifera (Horv.) and Nephotettix virescens (Dist.) (impicticeps/shihara).
