The research was conducted from 1997 to 1998 in the western region of Poland called Wielkopolska, on loessial, clay-based soil, valuation class III. The subject of investigation were 9 strawberry cultivars: Kent, Elsanta, Gerida, Senga Sengana, Marmolada, Vicoda and Pandora, and 2 cultivars of Polish origin: Elkat and Seal.

Some biological features were evaluated, such as the growth of plants, their expansion, crown and runner production, blooming, fruit-ripening dates, crop yields and mean fruit mass were assessed in each harvest period. The cultivars Marmolada, Vicoda, and Gerida were distinguished by a stronger growth and a spreading shape of the plants. Elsanta, Senga Sengana, and Pandora grew more weakly. One-year-old plants of Senga Sengana and Elkat had the most crowns, while the plants of Seal had the fewest crowns, followed by Vicoda and Elsanta. Elkat had the most runners (with an average of 23 per plant). Similarly, the plants of Pandora, Gerida, Senga Sengana and Marmolada produced numerous runners. Elsanta had the fewest runners. Senga Sengana was also that with the most inflorescences and flowers, while Pandora and Elsanta had the fewest inflorescences and Seal and Elsanta the fewest flowers.

Kent had the earliest fruit of all cultivars each year, with Elsanta closely following, while Pandora and Vicoda gave the latest ripe fruit. In the 3-year period Kent had the highest yields, with a total of 445 kg/100 m2 and a commercial yield of 335 kg, the second was Vicoda (441 and 337 kg, respectively), Pandora (with 439 and 329 kg), and Marmolada (426 and 340 kg). Each year the lowest yields were obtained from Elsanta (198 and 165 kg), followed by Seal (225 and 188 kg) and finally Senga Sengana (287 and 186 kg). On the other hand, Vicoda and Marmolada were characterised by large berries with the highest mass, whereas the smallest fruit was obtained from Senga Sengana, with Seal, Elsanat and Elkat following.
