Apple assortment replenishment with varieties of ARRIFCB breeding in 2011-2016

All-Russian Research Institute of Fruit Crop Breeding (ARRIFCB) is the author of more than 50 apple varieties included in the State Register of breeding achievements admitted for use in the regions of the Middle Zone of Russia. Brief economic and biological characteristics of 4 new apple varieties from 10 varieties created during the last 5 years (2011-2016) are presented in this paper. Two varieties (‘Dariona’ and ‘Osipovskoye’) are of summer maturing and two varieties (‘Vostorg’ and ‘Priokskoye’) are of winter consumption. Both summer triploid varieties are characterized by more regular fruit-bearing, fruit marketability and higher autogamy. ‘Dariona’ has been created from the intervalent crossing of 2x x 4x type (‘Melba’ x ‘Papirovka tetraploid’) and has beautiful marketable fruit with 170 g weight. ‘Osipovskoye’ is characterized by marketable dessert fruit. Two winter columnar apple varieties presented in this paper are characterized by high autogamy, productivity and scab immunity (gene Vf). From columnar varieties the variety Priokskoe is most interesting, in our opinion. It gives high yields and has beautiful marketable fruit with 150 g weight. Its fruit are evaluated by 4,5 point for appearance and 4,4- 4,5 points for taste according to the 5-point scale. “Priokskoye’ is distinguished by high contents of sugars (12,2%) and P-active substances (312 mg/100 g) in fruit. The involving of new varieties into the commercial orchards and amateur gardens will undoubtedly give a positive result in providing people with fresh home fruit and will ensure the health of people.
