This article presents the study on the behaviour of a local apple variety 'Măr dulce’ in the process of pollination with two valuable varieties that are found in the European assortment. It was studied the behavior in the pollination process of two hybrid combinations C1 - 'Măr dulce’ x 'Orion’ and C2 - 'Măr dulce’ x 'Bistrițean’ where the maternal parent is the old apple variety 'Măr dulce’ and the paternal parent is represeted by pollen from the apple varieties 'Orion’ and 'Bistrițean’.This study provides a novelty for a future selection of elite genotypes for the production of hybrids with an increased resistance to Venturia inaequalis.The studies were conducted in the spring of 2019 and the controlled pollination method was used, which involves a number of steps as: pollen harvesting, pollen maturation, castration of the maternal parent, pollination when the ovarian exudate appears on the stigma and isolation of pollinated branches. After these steps, the number of linked flowers, the number of maturated hybrid fruits and the growth of hybrid fruits resulting from C1 and C2 hybrid combinations were studied.
