Pollen viability of 11 strawberry cultivars differing of photoperiodic sensivity was investigated. During whole flowering period, average content of fertile pollen of everbearing fruit cultivars amounted 28.5 percent and remained at the same level, whereas day-neutral cultivars in third decade of June and July decreased at 35.2 percent in comparison to May level. Radiolographic analysis of plump seeds of 5 strawberry cultivars confirmed close relationship between pollen fertility and the plump of seeds
