The article presents the results of evaluation of garden strawberry (Fragaria ananassa) varieties for productivity components (quantity of flower bearing stems for a bush, berries quantity for a flower bearing stem, the average berry weight) in the Republic of Belarus. High productivity potential is marked at the varieties which have 7 and more flower bearing stems for a bush, the average berry weight of 10.1 g and more and compact inflorescence type. Among them there were varieties 'Dukat', 'Rusich' and 'Alpha'. Strong direct correlation links were revealed between such traits as 'quantity of flower bearing stems for a bush' and 'productivity' (r = 0.97), 'quantity of flower bearing stems for a bush' and 'average berry weight' (r = 0.79), 'average berry weight' and 'productivity' (r = 0.89). Also strong back correlation links were distinguished between the following traits 'quantity of flower bearing stems for a bush' and 'berries quantity for a flower bearing stem' (r = 0.80) and finally 'berries quantity for a flower bearing stem' and 'productivity' (r = 0.85). Using the given links let carrying on breeding research for high productivity and marketability of berries for flower bearing stems not taking into account weight of yield.
