Complex comparative evalution of 19 genetically varied lines of determinate and semideterminate tomatoes for fresh consumption and proccessing was made in field and vessel experiment for their response to economically important for the Republic of Bulgaria diseases, caused by Verticillium dachliae, Fusarium oxysporum, Fusarium oxysporum f.sp. radicis-lycopersici, Phitophtora infestans, Botrytis cinerea, Alternaria solany. All these lines are a result from previous selection by economic properties. There are no perfect immune to the Verticillium wilt among the obtained materials. The lines Nos. 95/2, 980, 986, 1106, 1219, 1125, 1227 and 1237 possess very low values for development of these diseases by which the indices of Verticillium and Fusarium wilt development vary from 2 to 20 per cent. The lines Nos. 95/2, 980, 1035 and 1237 are resistant to the Fusarium wilt but inn both of them Nos. 95/2 and 1237 this resistant was combined with the resistance to other diseases, including the Verticillium wilt. The combination of these properties in the above-mentioned materials plays an importannt role in further breeding purposes.
