Resistance of rice varieties to striped rice borer

Resistance of rice varieties to striped rice borer

M.D. Pathak, F. Andres, N. Galacgac, R. Raros

Ten thousand varieties and lines of rice ( Oryza sativa L.) from all over the world were screened for resistance to stem borers, Chilo suppressalis Walker, at the International Rice Research Institute, Los Baños, Philippines. Planting the test varieties between the main cropping seasons usually resulted in heavy borer infestations of the crops. The varieties selected from first screening tests were retested in four to five replications. The selected varieties were also evaluated by infesting them artificially with an equal number of striped borer larvae in greenhouse experiments.
