Technical Abstract: The collection of wild sugarbeets (Beta) has received increased attention in recent years because their natural habitats are continually being destroyed. Very few accessions of wild Beta from the section Corollinae have been collected from their native habitats in the Caucasus Mountain region of the Soviet Union. An exploration was conducted to collect wild Beta from the Caucasus region of the Soviet Union. Seed was collected from three populations of B. corolliflora, one population of B. lomatogona, and two populations of B. macrorhiza. All species are perennial, cold and winter hardy, and drought tolerant. Tolerance to saline soils has been observed in B. lomatogona. Resistance to curly top (a devastating virus of sugarbeet in the western U.S.) has been identified in B. corolliflora. It has been more than 50 years since the U.S. has collected wild sugarbeets in the Soviet Union, so the recently acquired accessions fill a gap in the Beta germplasm collection. Considerable evaluation of the collected materials will be needed to determine their potential value. The new germplasm will facilitate efforts to improve cultivated sugarbeet by introducing new genes from the wild species. It will also allow for the preservation of valuable sugarbeet germplasm for future use.
