Origin & Breeding History: 'Polares' was bred and developed by the breeders, Stanislaw Pluta and Edward Zurawicz, both employed at the Instytut Ogrodnictwa (Research Institute of Horticulture), in Skierniewice, Poland. It originated from a cross conducted in 1994 at the Experimental Station in Dabrowice, Poland, between the breeding clone designated 'S12/3/83', as the female parent, and the breeding clone designated 'EMB 1834/113', as the male parent. Seedlings derived from the cross were planted in the field in the spring of 1995 and evaluated from 1997 to 2000. 'Polares' was selected in 2000 for its plant growth habit, good fruit productivity, fruit size, high fruit quality, disease resistance and winter hardiness. It was further tested from 2000 to 2008 at the Experimental Station in Dabrowice. 'Polares' was first propagated asexually by hardwood stem cuttings in 2012, in Skierniewice, Poland.
Tests & Trials: The detailed description of 'Polares' is based on the Report on Technical Examination, reference number RS 842, purchased from the Centralny Osrodek Badania Odmian Roslin Uprawnych, in Slupia Wielka, Poland. The trial was conducted by the Centralny Osrodek Badania Odmian Roslin Uprawnych, in Slupia Wielka, Poland, from 2010 to 2013.
