Rubus fruticosus MARYNA

A new Polish-bred cultivar distinguished by exceptionally large fruit, reaching up to 3.5–4.0 cm in length and weighing 8.5–10 g. Thanks to its high sugar content, with soluble solids reaching up to 13%, the fruit is aromatic and sweet. The approximate yield per bush is 3–4 kg. The cultivar is also resistant to diseases, including anthracnose and cane dieback. The fruit shows low susceptibility to rot and color reversion during storage. Its high firmness and excellent texture allow for storage under refrigerated conditions (5–9°C) for up to two weeks. The plant is characterized by moderate vigor and an upright growth habit, reaching up to 2.5 m in height. The leaves are intensely dark green with a slight gloss, deeply serrated, and curled upward along the margins. This cultivar fruits on second-year canes in June and then produces a second crop on current-season canes from early September onward. Fully ripe berries have an attractive, uniform black color with a glossy appearance. They are exceptionally firm and are particularly recommended for the fresh market as dessert fruit. The cultivar is recommended for both commercial plantations and home gardens. Hardiness zone: 5b (–26 to –23°C).
