In 2007-2009, eighteen gooseberry (Ribes grossularia L.) cultivars were evaluated in the growing conditions of central Poland. They were 'White Smith', 'Captiva- tor', 'Hinnonmaki Gelb', 'Hinnonmaki Rot', 'Invicta', 'Kamieniar', 'Krasnoslavian- ski', 'Laskovij', 'Macurines', 'Misorskij', 'Niesluchovski', 'Pax', 'Pixwell', 'Pusz- kinskij', 'Rochus', 'Rolonda', 'Ruskos' and 'Spine Free'. The following cultivar features were assessed: fruit yield (date of ripening, yield, size of fruits and colour of fruit skin), susceptibility to fungal leaf diseases: American powdery mildew Sphaero- theca mors-uvae (Schwein.) Berk. et Curt. and leaf spot Drepanopeziza ribis (Kelb.) Petrak, plant growth (the height and the width of bushes) and plant habit. Cultivars 'Niesluchovski', 'Hinnonmaki Gelb', 'Hinnonmaki Rot' and 'Invicta' were the earliest to ripen. Fruits of 'Captivator' and 'Spine Free' ripened the latest. The highest fruit yields were harvested from the cultivars 'Pixwell', 'Puszkinskij' and 'Laskovij', and the lowest were from 'Ruskos', 'Pax', 'Hinnonmaki Gelb' and 'Niesluchovski'. The various cultivars differed in the colour of the fruits. They produced green, yellow, light red, red, and dark red fruit skins. The most susceptible to American powdery mildew were 'White Smith' and 'Krasnoslavianski'. The remaining cultivars showed very little infection or they were not infected at all. The leaves of all cultivars were affected by leaf spot in the low or medium range, except for the cultivar 'White Smith', whose leaves were highly infected by this disease. The bushes of the cultivars 'Pixwell', 'Ruskos', 'Laskovij' and 'Misorkij' grew the most vigorously. 'White Smith', 'Niesluchovski' and 'Hinnonmaki Gelb' produced the smallest plants. Cultivars 'Macurines' and 'Puszkinskij' were characterized by the widest spreading plant habit.
