Abstract. The morphological and reproductive manifestations as well as the chemical composition of seven introduced, indeterminate tomato varieties, grown in greenhouses in the Maritsa Vegetable Crops Research Institute, Plovdiv were studied in the period 2012 – 2013. The tomato plants are transplanted in February and grown according to the conventional technology for late production. The indices determining the growth and reproductive manifestation of the plants were studied by the method for comparative variety investigation. It was established that the greatest average fruit weight – 246 g was observed in variety Beladona. The variety Kiveli exceeds the remaining by earliness. The highest total yield – 212220 kg/ha is recorded in variety Panekra. The content of the basic chemical components of the fruits is the greatest in the varieties Setia, Afen and Rashel. The total sensory evaluation is the highest in the varieties Beladona and Setia.
