Studies on the resistance of Tong-il variety (IR-667) to the brown planthopper, Nilaparvata lugens Stal


, : Studies on the resistance of Tong-il variety (IR-667) to the brown planthopper, Nilaparvata lugens Stal. Korean Journal of Plant Protection 11(2): 61-68

Studies in Korea showed that some lines of rice (Suwon 213, 213-1, 214 and 215) bred from the Tong-il (IR-667) variety were slightly more resistant to attack by Nilaparvata lugens (Stal) than the japonica varieties recommended for Korea, but were more susceptible than some of the Korean varieties. The planthoppers laid more eggs on the resistant varieties (which suffered reduced feeding damage) than on susceptible varieties and lines.
