The study of the behavior of the new apple varieties Gala Buckeye Simmons, Granny Smith (control), Red Velox, Golden Delicious Reinders and Fuji Kiku, grafted on the vegetative rootstock M9, was carried out at SRL "Elit Fruct" from the village of Coșernița, Criuleni district, in the period 20223-2023. Certified planting material was used. The orchard was established in 2015 at a distance of 3.2 m between rows and 0.8 m per row with a density of 3900 trees/ha. Tree growth, plantation structure parameters, growth and fruiting potential of apple varieties were studied. The vertical placement of fruit set and fruit formation is relatively uniform, showing a tendency to decrease towards the top of the tree: 37-43% of the crop is placed at a distance of 60-160 cm from the ground, 31.2-36.4% of fruit - at 160-240 cm, and no more than 24.4-29.2% of fruit is formed in the upper part of the crown. Harvest of fruits in 2022 in LLC "Elit Fruct" referred to the category "Extra" (69,5-73,4 %) and category I (21,7 -24,2 %). In 2023, apples of category "Extra" constitute 75,3 - 85,3 %, those of category I were 12,7 - 17,2 % and only 2,0 - 7,5 % refer to the category.
