ORIGIN: The variety Keřkovské rohlíčky (Višňovské rohlíčky x Parnasia) was bred on Keřkov Breeding Station in 1940. It became very popular and sought after especially for its extraordinary suitability for salad preparation. Despite several problems (lower yield, lower resistance to viral diseases etc.) it was included in our variety assortment till 1984. Since in further years the interest in specific characters of this variety was not reduced, the department of biotechnologies of Potato Research Institute Havlíčkův Brod initiated activities for recovery of this variety. After three-year tests the variety was entered into the List of registered varieties in 1995 and this work was awarded by granting “Golden Ear 1995” during international agricultural fair “Bread Basket”.
