Economically important diseases on tomatoes in Bulgaria are bacterial speck and bacterial spot caused by Pseudomonas syringae pv. tomato (Okabe)Young et al. and Xanthomonas vesicatoria (ex. Doidge) Vauterin et al., respectively. The efforts of the breeding scientists are oriented toward searching for resistance in tomato wild species and creating new resistant tomato cultivars. Thirteen accessions of wild tomato species belonging to subgenuses Eulycopersicon and Eriopersicon of genus Lycopersicon were examined. Investigated from us accessions are characterised for different degree of resistance to P. syringae pv. tomato (0, 1) and X. vesicatoria ('1, '3). Resistant to race '1 and '3 of X. vesicatoria are L. pimpinellifolium LA 121 and L. chilense CGN15531. Sources of resistance to P. syringae pv. tomato race 0 and 1 are not found.
