Male sterile indica rice plants that were sensitive to brown planthopper (Nilaparvata lugens) were crossed as females with Oryza officinalis ( which is highly resistant to N. lugens. F1-F4 hybrids from one of the cross combinations exhibited resistance to N. lugens. Among these 21 lines, 18 had medium to high resistance. For the other 2 cross combinations studied, green plantlets were regenerated from in vitro cultured rescued immature embryos.
