Abstract

Evaluation of the selected eggplant varieties produced very promising results this year. Four eggplant lines showed resistant reactions to bacterial wilt disease, and seven to root-knot nematode. Eleven eggplant varieties/lines exhibited high to moderate resistance to fruit and shoot borer (FSB) consistently for two years under both natural and artificial infestation conditions. Antibiosis and antixenosis tests strongly indicated that these varieties are genetically resistant to FSB. The selected FSB-resistant varieties include two cultivated varieties, Kazla and Uttara, which if cultivated widely can minimize FSB infestation effectively and will ultimately reduce pesticide use at the field level. These varieties have also some degree of resistance to jassids, aphid and white fly. Several of them have cross resistance to bacterial wilt and root-knot nematode. Identification of these resistant materials have enhanced the process of producing pest-resistant varieties.
