Abstract

The cultivation of sugar beet as an autumn sown crop requires an improvement of winter-hardiness. To assess the genetic variation of winter-hardiness 396 Beta vulgaris accessions in 8 environments in Germany and Belarus were evaluated. The results revealed significant differences of survival rates across accessions, B. vulgaris forms and environments. The observed winter-hardiness of the B. vulgaris gene pool is sufficient for the cultivation of autumn-sown sugar beet under mild, maritime winter conditions. However, for the cultivation of autumn-sown sugar beet under continental conditions an improvement of winter-hardiness is mandatory. On a short term scale, winter-hardiness of sugar beets can be improved by selection within sugar beets. On a long term scale winter-hardiness can be improved by introgression from pre-selected wild beets (Beta vulgaris ssp. maritima).
