The search for this new specific tolerance to an ALS-inhibiting-herbicide and the development of the first generations of varieties was a dedicated piece of KWS research and development.
It took more than 15 years of enthusiasm and commitment of an engaged team of KWS researchers and breeders to develop this strategic new approach for sugar beet. Out of 1.5 billon individuals one single herbicide tolerant individual was naturally found, which formed the basis for the development of the new CONVISO® SMART system.
The tolerance of the new SMART KWS varieties has been obtained through a naturally occurring change in an enzyme involved in the biosynthesis of essential amino acids. Sugar beet plants with this spontaneously changed enzyme were specifically selected and used for further breeding to develop SMART KWS varieties.
The sugar beet weed control system CONVISO® SMART is jointly being developed by KWS SAAT SE and Bayer AG.
