SUGAR BEET VEGETABLE MATERIAL RESISTANT TO HERBICIDES, PROCESS FOR PRODUCING HERBICIDAL RESISTANCE IN SUCH VEGETABLE MATERIAL, METHOD OF IMPARTING RESISTANCE TO HERBICIDES TO SUCH VEGETABLE MATERIAL AND METHOD OF CONTROLLING GROWTH OF WEED IN THE PRESENCE OF THOSE PLANTS

摘要

Sugar beet plants which are resistant to both imidazolinone and sulfonylurea herbicides are described. The sugar beet plants are derived from susceptible cells by sequential selection of SU-R cells, plant regeneration, and re-selection for IM-R. The resistant sugar beet plants derived from the cells can be grown in fields where imidazolinones and sulfonylureas have been used for weed control.
