Abstract

One hundred and fourteen cultivars of rice (Oryza sativa L.) identified as resistant to brown planthopper (Nilaparmta lugens Stal.), at Hyderabad were evaluated for their reaction to whitebacked planthopper (Sogatella furcifera Horvath). Fifty-five cultivars were found to be resistant. Possibility for biotype differentiation in the insect is indicated because of differences in reactions of some of the cultivars from those observed in the Philippines.

Genetic studies in crosses involving some of the whitebacked planthopper resistant cultivars indicated that resistance in cultivars `PTB33,' `ARC14636,' and `ARC 14766′ is governed by a single dominant gene, whereas resistance in varieties `ARC 6650′ and `ARC14394 is conferred by a single recessive gene.
