Abstract
Reaction of F3, F4 and F5 lines of rice to the brown planthopper at seedling and maturing stages were observed in the second crop of 1981 at Chiayi Agricultural Experiment Station. Preliminary results revealed that some of the hybrid lines which were resistant at seedling stage became susceptible at maturity stage whereas some moderately susceptible lines at seedling stage appeared resistant when they were fully matured. The switch from resistance to susceptibility was more pronounced for Japonica lines than Indicas. From this observation, it was inferred that some lines might possess adult resistance which would be of potential importance in the future breeding program. Also, certain modifications on the current screening method might be required to further improve the efficiency of selection.
