Abstract

In vitro screening of resistant mutants of eggplant to Verticillium daliae was studied with Verticillium daliae toxin and tissue culture technology.The induction rate in stem on medium of MS medium + IAA 1 mg/kg + NAA 1 mg/kg + KT 0.2 mg/kg was higher than that of in hypocotyl and cotyledons.The toxin concentration of 15% was considered as the selection pressure of resistant mutants of eggplant to Verticillium dahliae.The resistance of callus to Verticillium dahliae toxin could be improved by increasing the concentration gradually.
