Abstract

Fifty plant introduction lines of pepper were screened for resistance to curly top virus using the vector Circulifer tenellus Baker and a strain of virus known to be pathogenic on peppers Inoculations were done by caging either 3 or 15 viruliferous leafhoppers onto a leaf at the 4-true-leaf stage of growth. Four lines (PI 257053, PI 281297, PI 288938, and PI 357522) showed apparent resistance when inoculated by 3 leafhoppers, but non appeared resistant for more than a few days when inoculated by 15 leafhoppers. No correlation was found between leafhopper longevity on a plant and that plant’s resistance to the virus.
