The Tatyatin Day apple variety is a late-winter variety with a long fruit storage period, bred at Lomonosov Moscow State University. The tree has medium growth strength, a wide-round crown, and sturdy branches branching off the trunk at a right angle. The leaves are large, oblong, and dark green. The fruits of this variety are large, flat-round, with greenish-yellow skin adorned with blurred red stripes. The apple flesh is juicy, fine-grained, acid-sweet, and without a pronounced aroma.
Harvesting is recommended in the middle or second half of September, allowing fruits to be consumed immediately after gathering when the taste is more acidic. With proper storage, apples retain their taste and freshness until March, making the variety particularly attractive for long-term use. The variety is distinguished by good winter hardiness and resistance to scab, as well as a high content of r-active substances in the fruits.
The Tatyatin Day apple tree is characterized by high productivity, early fruiting, and drought resistance, making it suitable for cultivation in the central region of Russia. However, the variety has some disadvantages, such as susceptibility to powdery mildew, rust, and gray mold, as well as susceptibility to pests, including aphids, flea beetles, and codling moths. Despite this, the variety is popular due to its large fruits, long storage period, and good taste qualities.
