Pepper Lends Its Nematode Resistance to Double-Cropped Vegetables
Agricultural Research Service, United States Department of Agriculture.
Washington, D.C. (June 23, 2004) - The Charleston Belle pepper developed by the Agricultural Research Service continues to impress researchers with its ability to resist major root-knot nematodes afflicting the southern United States.
A recent ARS study not only confirmed the effectiveness and heat

Charleston Belle peppers--released in 1997 by ARS Vegetable
Laboratory geneticist Richard Fery--get their resistance from the N gene, which
was obtained from a resistant pimiento pepper and placed into Keystone cultivars
to create Charleston Belle. The gene controls resistance to three major
root-knot nematode species: southern (Meloidogyne
The pepper's resistance may aid growers who, next year, must
Other, independent studies have shown that nematode-resistant
vegetable plants--notably tomatoes--can help shield double-cropped vegetables
from nematode attack. In the ARS study, cucumber yields were 87 percent heavier
and numbers of fruit were 85 percent higher when grown after Charleston Belle
than after Keystone. Squash yields were 55 percent heavier, with 50 percent more
