Evaluation of strawberry varieties for productivity components

Abstract

The article presents the results of evaluation of strawberry varieties for productivity components (quantity of flower bearing stems for a bush, berries quantity for a flower bearing stem, the average berry weight) in 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 the 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.
