The varieties have been developed by Kent grower Peter Vinson, of the Faversham-based Edward Vinson Breeding Programme.
The Edward Vinson farm is also producing the new varieties, which are being sold exclusively to BerryWorld. The supplier claims the varieties, available from early May through to the end of October, offer considerable improvement in flavour, appearance and yield on other everbearers that are available.
BerryWorld technical director Tim Newton said: "These two varieties will enable BerryWorld to provide consistent and top-quality strawberries on the shelves for consumers as well as create a longer season from the same plant for the producers. Both have proved extremely popular in 2007 comparative taste panels."
Vinson, who is also chairman of BerryWorld, added: "As the programme is maturing it is exciting to see significant advances in flavour and other aspects of quality which these two varieties represent. We have created germplasm (genetic material) which will lead to more improved varieties in the future."
