It is important to investigate correlation between tomato cultivar and the area climatic conditions. Eight cultivars (Chef, Campbell 33, Rio Grande, Zenit F1, Diddy F1, Professional F1, Lerica F1, Brixy F1) were comprised by the the micro tomato experiment in the Poreč region. The tomato was grown from seedlings and transplanted into a polyethyl plastic sheet. Important dates were recorded. Fruits mass and their uniforming, shape and colouration were determined. Percentage of dry matter as well as pH were also determined. Fruits classification was carried out. Soil tillage and fertilization were performed according to experimental site conditions. Fruits mass did not considerably differ. There are significant differences among fractions. Professional F1 and Campbell 33 were considerably robust cultivars (P =1%). The highest yield was obtained with Rio Grande (42.37 t/ha), significantly higher compared to Diddy F1. Other cultivars were relatively uniform.
