An old heirloom tomato from Czechoslovakia. Bred by a famous Czech tomato breeder Jaroslav Homola in the 1940s, from a cross of Mikado x Sláva Porýni x Solanum racemigerum. The breeding efforts took place on a state-owned Stupice farm founded in 1921 (Stupice is a small village near Prague, Czechoslovakia). The farm was nationalized in 1948, then privatized again after 1989, and the ‘rights’ to the tomato was given to firms Sempra Praha, Seva Seed and Moravoseed. (‘polní’ means ‘field’ and ‘rané’ means ‘early’ in Czech language.) Introduced commercially in North America by Tatiana’s TOMATObase Seeds in 2015. Compact indeterminate, potato leaf plants produce a high yield and a very early crop of 1.5-2.5 oz., red, round, blemish free fruit with excellent rich flavors.
