Gardeners and summer residents grow apple varieties on their plots, which give a good harvest and do not require too painstaking care. These are the proven varieties called Imrus with a long history of cultivation and development.
Breeding history of the variety
The domestic apple variety was bred by the method of hybridization by Russian breeders Khabarov, Sedov, Zhdanov and Serova more than 40 years ago, but it was introduced into the State Register only in 1996. The variety was obtained due to the successful crossing of Antonovka ordinary and hybrid species of late ripening OR18T13.
Description of the variety
The Imrus apple tree is a medium-sized tree, reaching a height of 4-6 meters, with a rounded moderately dense crown. Since the branches of the tree diverge from the trunk at an acute angle, heading towards the sun, the apple tree does not take up much space and can grow in a small garden area.
Features, pros and cons
Imrus is a fast-growing winter variety, characterized by high yield rates, winter hardiness, and unpretentious care. Along with the standard characteristics, the apple variety has its own characteristics: resistance and resistance to scab and powdery mildew, provided by a specially embedded VF gene, quick adaptation to different types of soil, as well as high taste. Among the shortcomings, one can point out the excessive thinness of the peel, the tendency of the fruit to shedding, as well as poor self-pollination.
Ripening and fruiting
The active flowering of the tree begins quite early (first half of May) and is characterized by the appearance of small pale pink flowers, which cover almost the entire crown. Fruiting begins in the third year of tree growth, but the highest yield level is observed in the 7-8 year. The consumer period lasts until early March. The timing of flowering and fruiting can be shifted under the influence of weather disasters. For this variety, fruiting of a combined type is characteristic, when an apple tree bears fruit on complex and simple ringlets.
Do not forget that the first harvest will be very modest, but all subsequent ones will certainly please.
Growing regions
Due to its excellent resistance to frost, drought and heat, the apple tree easily takes root in any climatic conditions. Today, the variety is planted in the central zone of the country, as well as in Belarus and Ukraine, but this does not mean that the apple tree is not recommended to be grown in the northern regions.
Yield
The yield indicator for the variety is quite high. The first fruits can be tasted from mid-September. On average, under favorable climatic conditions and proper care, up to 20 kg of apples are harvested. From an adult tree, you can get up to 90-100 kg of fruits.
Fruits and their taste
Medium-sized apples (weighing up to 190 grams) are characterized by a regular turnip shape, greenish color with yellow inserts, and a thin skin with a glossy finish. Fruit taste is harmonious, sweet-sour, with a pronounced aroma. The taste of apples becomes most pronounced after full ripening.The advantages of apples are their high juiciness and meatiness, due to which the fruits are not only eaten fresh, but also processed into juice, jams, purees, and preserves.
Growing features
The optimal place for growing the variety is fertile soil with moderate moisture - loamy or sandy loam. Before planting, you need to prepare the soil by clearing it of weeds and digging it thoroughly so that the soil can breathe. In the area where the Imrus apple tree grows, there should be a lot of sun and light, but areas with drafts and close groundwater should be avoided.
The optimal season for planting seedlings is early autumn (late September - mid-October), so that the root system adapts to frost. When choosing a site, do not forget that you need to plant an apple tree away from other trees (the only exceptions are other apple varieties). Subject to the elementary rules of agricultural technology, even a beginner can cope with planting and growing this variety.
Pollination
The pollen of the variety is endowed with an average level of viability, and as a result of free pollination, up to 20% of the fruits are tied. There are no exact data on pollinating varieties yet, but biologists are studying this issue.
Top dressing
Top dressing is one of the important components of the complex care of a fruit tree. The most acceptable are organic fertilizers, which are applied according to the established schedule. In addition, wood ash is considered a safe option. In addition to feeding, do not forget about watering and pruning damaged and old branches.
Frost resistance
This variety is very hardy. It perfectly tolerates temperatures up to -40 degrees in winter, which does not affect future yield indicators. Before winter, mulching is carried out around the trunk, which will protect the tree in severe frosts.
Diseases and pests
The variety has absolute immunity to scab and powdery mildew, but preventive measures should be taken. As a rule, this is the treatment of the trunk and spraying of the tree with special solutions. Sometimes, through the fault of the gardener, some diseases in the Imrus apple tree still occur - this is black cancer and bacterial burn, which will require the removal of diseased branches or areas of bark.
The apple tree is a popular fruit crop among gardeners. It can be found in many summer cottages. But at the same time, such trees are often affected by various diseases. It is very important to recognize the disease in time and carry out the necessary procedures for a speedy recovery. Otherwise, the fruits will be spoiled, and the tree itself may die altogether.
Review overview
Both summer residents and farmers who pursue commercial goals like to grow the Imrus apple variety, since the species is not at all capricious in its care, it quickly adapts in different soils, with the exception of heavy clay, and also gives incredibly tasty fruits.
Most amateur summer residents note the high yield, the beauty of the tree during the abundant flowering in May and, of course, the unforgettable sweet and sour taste of apples. Farmers point to the long shelf life of apples, as well as their easy transportation, even over long distances.
