At Polli Horticultural Research Centre currently over 400 apple accessions are being maintained, including 47 local cultivars and 14 scab resistant cultivars. Cultivars „Imrus‟, „Chistotel‟, „Orlovim‟, „Pamyat Issayeva‟, „Pervinka‟, „Pioner Orlovski‟ and „Slavyanin‟ were introduced from the All-Russian Research Institute of Breeding of Horticultural Crops at Orel. Cultivars were assessed for tree phenology stage, weight of the fruit, yield per tree, occurrence of apple scab and the biochemical content of the fruit. No scab infections were found on these cultivars during the evaluation years at Polli. „Orlovim‟ was the earliest and „Pioner Orlovski‟ the latest bloomer. „Chistotel‟ and „Slavyanin‟ achieved the highest yield per tree. „Pamyat Issayeva‟ and „Pervinka‟ gave the largest fruits. All 7 cultivars possessed relatively high levels of acidity and because of that they are not best suited for fresh consumption.
