Some of these stresses include a seedling disease caused by the fungus Aphanomyces cochlioides, a root rot disease caused by Rhizoctonia solani, a leaf spot disease caused by Cercospora beticola, and a suite of weather-related stresses that creat problems obtaining adequate stands of sugar beets. The breeding program at East Lansing is geared towards releasing improved germplasm with tolerance or resistance to these stresses. In addition, breeding for improved quality and yield of sugar is continuing along with breeding for the smooth root characteristic. Smooth roots lessen the amount of adhered soil on harvested beets compared with traditional deep cleft root, avoiding problems of transport, processing and disposal of unwanted and potentially infested soils. The East Lansing breeding program will continue to release improved germplasm to the United States sugar beet industry, as well as provide new knowledge regarding the measurement and selection of better varieties for the growing region. Additional program benefits will come in the future in the form of improved understanding of the number, action, identity, and location of genes controlling agronomic and economic traits and their application in integrated breeding approaches. |
