Seeds from “Biotekhnika”. Manufacturer’s description:

Indeterminate type. Mid-season (period from germination to ripening 100-110 days) variety. Plants are tall (1.5-2 m / 5-6.5 ft). The fruits have a truncated-square shape, large (weighing 200-220 g / 7-7.7 oz), bright red, meaty. Sugary flesh, practically without juice. Excellent dessert taste. It features good yield (4-5 clusters of 5-6 fruits on the plant). Intended for fresh consumption and stuffing.

I agree with the description, low-juice for thick sauces and stuffing. For me in 2024, it turned out to be the earliest of the indeterminates. Height about 1.5 meters (5 ft), very productive.
