The breeding began in 1996 on a hobby basis. The goal was to develop oilseed rape with a higher feeding value of the meal and less need of insect treatments. During the years the breeding developed into several new directions.
Unlike other oilseeds such as linseed, sunflower seed and sesame, whole seed from oilseed rape is not used as an ingredient in bread or other products. Why: Before ca. 1975 rapeseed contained high amounts of erucic acid which was regarded harmful to humans.
However, the last 30 years almost only low erucic acid varieties have been grown in Europe and most other countries. Furthermore, in old varieties grown before ca. 1980 the amount of glucosinolates in the seed was high (90 – 150 μ moles / g seed). This level of glucosinolates (GL) is known to be harmful to animals when rapeseed or meal is fed in large amounts.
Today the GL content is less than 18 μ moles / g seed, regulated by the European Union. In contemporary varieties, erucic acid and glucosinolates should not be a problem for human consumption of rape seeds. What remains an obstacle is their penetrating taste.
However, seeds from our varieties have a mild and pleasant taste and are very well suited for ingredient in breads and other baked products. So we try to get a permission to use those mild seeds as a new food ingredient.
After hobby scale breeding from 1996 the company ‘Knold & Top Plant Breeding’ was made in 2002. In 2010 this was replaced by two private limited companies ‘Knold & Top ApS’ and ‘Knold & Top Holding ApS’.
Knold & Top ApS is a private limited company owned by Knold & Top Holding Aps, also a private limited company. The breeding takes place in the Nordic Seed facilities, c/o Nordic Seed A/S, Grindsnabevej 25, DK 8300 Odder. Knold & Top benefits from a narrow cooperation with Nordic Seed especially regarding the breeding and testing of oilseed rape for oil. Inside horticulture Knold & Top cooperates closely with Vikima Seed, Industriparken 9, DK 4960 Holeby.
Income is mainly from seed sale and license fees. Participation in projects and consulting work also contribute to the economy. At the moment Knold & Top only deals with business to business sale.
In general our varieties for agriculture are marketed and sold through other seed companies or distributors.
