Bolting — sugar beet
Beta vulgaris Sugar Beet Group
The formation of a flower stalk in sugar beet during the first year of vegetation is an undesirable phenomenon known as bolting. It leads to the plant's premature transition to the reproductive phase, reduced productivity, and deterioration of the root crop's technological quality.
In the reference 37 varieties crop Sugar beet, where this is mentioned in the description.
Sugar beet is a biennial plant that normally forms only a leaf rosette and a root crop in the first year. Bolting is an abnormality in which the plant produces a flower-bearing shoot within the year of sowing. This causes the stored nutrients to be consumed for seed formation rather than root growth, resulting in a coarse root crop with lower sugar content and poor storage properties.
The trait is assessed as the percentage of bolted plants in a field. In breeding, a provocation background with early sowing dates in cold soil is used to test hybrid resistance by stimulating vernalization. For commercial crops, a level of 0.5% or more is considered critical, whereas the goal of breeding is complete resistance to premature bolting.
The primary causes for the emergence of flower stalks are the combined effects of low positive temperatures, which induce vernalization, and long daylight hours. Under these conditions, the plant's genetic system is activated prematurely, making the flowering process difficult to reverse within a single growing season.
