Abstract: | Thirty six tomato wild species accessions of the subgenera Eulycopersicon and Eriopersicon of the genus Lycopersicon were inoculated with race T1 and T3 of Xanthomonas vesicatoria by vaccum infiltration method. Degree of diseases was evaluated by scale of 0 to 4. It was established that some accessions
showed low degree of disease to race T1 and others to race T3. LA 2623 indicated very low degree of disease to race T1 and
was immune in inoculation with T3. LA 386 and LA 1297 manifested hypersensitive reaction to both races and PI 127826 to race
T3 only. The accessions possessing low degree of disease or hypersensitive reaction to race T1 and race T3 are new promising
sources of resistance to Xanthomonas vesicatoria. |
