The aim of this study was to identify the distribution of 'Ca. P. solani’ in the four Moldavian tomato varieties during growing season and to evaluate their productivity and fruit quality. Molecular diagnosis of phytoplasma was used. The most significant difference in the percentage of infected tomato plants between the studied varieties was recorded at the stage of mass ripening of fruits. It has been found that the varieties Elvira and Desteptarea were more susceptible to 'Ca. P. solani’ compared with Cerasus and Mary Gratefully. At the end of the period of vegetation all analyzed varieties were significantly loaded with phytoplasma infection. Differences in the indicators of productivity and quality of fruits in the studied tomato varieties were determined. In general, varieties that were more resistant to phytoplasma infection, respectively, had a higher yield and better fruit quality. Thus, we can conclude that, in addition to other plant diseases, climatic conditions of the year, some features of the genotype, etc., stolbur negatively affected productivity and, especially, reduced the quality of tomato fruits.
