Sažetak
Sugarbeet is a very important crop in the U. S. A. Because of the susceptible European sugarbeet varieties, which are grown in the beginning, U. S. sugarbeet breeders are started with development of sugarbeet with resistance to Curly Top (Curly Top Virus) and Cercospora Leaf Spot (Cercospora beticola Sacc.). The discovery of cytoplasmically inherited male sterility (CMS) and O-type is made possible to use heterosis for root yield, and the discovery of monogerm seed made possible to plant on final distance in row. The sugarbeet business is connected by non-profit Beet Sugar Development Foundation (BSDF), because of increasing quantity and quality of sugarbeet root production for sugarbeet factories. The BSDF is involved in a research, and also in education of the sugarbeet root producers. Main area for sugarbeet root production is in Minnesota and North Dakota, where is produced in 1994 year 11 million t of sugarbeet root, what is 36% of total U. S. A. production. The production of sugarbeet root is organized through cooperatives, and producers independently make decision which approved variety will plant. The produced sugarbeet root is paid on the quality basis.
