Abstract: The process of fruit set of 10 apple varieties (Malusdomestica) having a different percentage of flavonols and water-soluble substances (WSS) in the pollen was studied. It was determined that the cultivars having higher content of flavonols and WSS in the pollen have a greater tendency to self-pollination; they are also better pollinators while cross-pollination. The percentage of phlorizin level in the styles of flower pistils of the same apple varieties was detected. It was also identified that varieties containing higher level of phlorizin in pistils have less pronounced tendency to self-pollination; their fruit set is weak while cross pollination. The conclusions about the possibility of using the flavonols percentage level in the pollen and phlorizin one in the styles of pistils as parameters for evaluation of the propensity to self-pollination and cross-fertility of apple varieties were done.
