- Abstract
More than 170 years ago a biennial sugar beet was crossbred from annual wild species; a monogerm beet was bred in the 1960s. We are intensively breeding more powerful varieties with multiple resistances or tolerances to fungal diseases and nematodes. The current goal is to breed beets in which it will be possible to prolong the growing season via increasing its hardiness for safe wintering and solving the possibility of bolting regulation. The article presents information from the professional literature focusing on the importance and benefits of this breeding objective. The newly bred plants must have sufficient winter hardiness (frost resistance) to survive the winter (lethal temperature for beet is -7 °C) and they must not bolt and flower (when grown for bulbs), because low winter temperatures cause the plants vernalization, which promotes sugar beet bolting in the spring. These are two fundamental tasks for genetics and breeders. Over the next six to eight years, we can expect a prototype of winter sugar beet with significantly higher sugar production than the spring varieties.
