Columnar apple tree of the K 109 variety is a medium-height, winter-hardy, and frost-resistant rootstock that quickly enters fruiting: 100% yield is achieved by the 4th-5th year. The tree has a characteristic columnar shape with a branched crown, making it attractive to both gardeners and lovers of decorative plantings.
The fruits of the K 109 variety differ in round shape, medium size of 200–250 grams, and high taste quality. The flesh is white and dense, while the taste is sweet-sour, making the apples popular for both fresh consumption and processing. Thanks to good transportability, they easily maintain their appearance and aroma during long transportation.
The K 109 rootstock possesses high resistance to diseases and pests: it is resistant to scab, fungal diseases, and other aggressive factors. Seedlings are grafted onto a medium-height rootstock, which ensures good adaptation to various climatic conditions and increases overall productivity. Such a rootstock is ideal for commercial orchards and private gardens where both yield and fruit quality are important.
