The primocane variety, sweet, yellow-orange fruit, useful for fresh consumption and for processing. Variety was registered in 2019 year in Research Centre for Cultivar Testing (COBORU) under a breeding name NR126107

Breeder: Agnieszka Orzeł, Phd

The plant has a medium size. It makes some shouts, approx.1,5 m high. Shoots are light green, covered with numerous small thorns.

The fruit are firm, middle size, round, glossy. Depending on the stage of the harvesting maturity, their color ranges from light yellow to dark orange. They are delicious. They are marked by the high content of extract (11,7% Brix), the high content of vit. C and the high antioxidant capacity (indicators DPPH, FRAP). Polyphenols content is compared to ‘Polana’ variety (table 1). Fruit ripening. Jantar repeats fruiting, but it is mainly the primocane. Fruit ripening begins in the first week of August and usually lasts for 3-4 weeks. Usefulness of the variety: a dessert variety and also for processing, and for amateur cultivation. Susceptibility to diseases: plants are healthy, little susceptible to diseases of shoots and roots.
