New apple variety – Hrustal’nyj Bashmachok

Abstract

The domestic apple tree (Malus domestica Borkh.) occupies a leading place among fruit crops, both in terms of area planted and in terms of gross fruit harvest. Currently, apple tree varieties are subject to strict requirements for highly adaptability, winter hardiness, early fruiting, high yield and quality of fruits. The new apple tree variety Hrustal’nyj Bashmachok (breeding number 1-18), meets many of the listed requirements, is the result of breeding work of the Orenburg branch of the Federal State Budgetary Institution Federal Scientific Center for Horticulture, aimed at improving the assortment and meeting the demand of producers and consumers of agricultural products in the Ural region. A variety of autumn ripening, universal use, obtained from open pollination of Antonovki Obyknovennoj and combines in its genotype such valuable qualities as high winter hardiness, productivity, and resistance to scab. The tree is medium in size, with a rounded crown of medium density. Fruits with an average weight of 152 g, conical, regular in shape. The surface of the fruit is smooth, slightly ribbed, the main color at the time of harvest and consumer ripeness is greenish-yellow. The outer color is present on a smaller part of the fruit and is orange. Subcutaneous dots are small, white, barely noticeable. The fruit pulp is creamy, dense, juicy, fine-grained, with a medium aroma. The taste is sweet and sour, pleasant, tasting score 4.4 points, average aroma. The shelf life of fruits is 20-30 days. Chemical composition of the fruit: sugar content 10.8 %, ascorbic acid 19.1 mg/100 g, dry matter 13.4 %; acidity 0.8 %. The Hrustal’nyj Bashmachok variety has average drought and heat resistance, is slightly affected by scab, and begins to bear fruit in the third year after planting. Over a long period of study, the variety showed a high level of economically valuable traits, including yield from 14.8 to 18.8 t/year and stable annual fruiting. The Crystal Shoe variety has been included in the State Register of Breeding Achievements approved for use in the Ural region since 2022 and is recommended for updating the industrial assortment of the region and cultivation in farms of various categories.
