Interpretive Summary: F1030, F1031, and F1032 sugarbeet, germplasm lines were released by the USDA-ARS in 2013. All three lines were selected primarily for sucrose concentration from populations formed by crossing a high-sugar line with three previously released germplasm lines that originated from a cross between a cultivated line and a wild relative of sugarbeet from Greece. The average sucrose concentration of the three germplasm lines was 1.5 % greater than the average of the three cultivated X wild parental lines and 0.8 % less than the average sucrose concentration of a commercial hybrid. The average root yields of F1030, F1031, and F1032 were 54, 75, and 63% of the root yield of a commercial hybrid. When used as components in the development of advanced breeding populations, F1030, F1031, and F1032 will contribute to a broadening of the genetic diversity within the commercial sugarbeet crop. The primary objective when crossing wild relatives with cultivated lines is the introduction of traits/genes not found in the cultivated germplasm or to expand the available genetic diversity and thereby increase the limits of selection for agronomic traits.

Technical Abstract: F1030 (PI 671774), F1031 (PI 671775), and F1032 (PI 671776) sugarbeet, Beta vulgaris subsp. vulgaris (L.), germplasm lines were released by the USDA-ARS in 2013. All three lines were selected primarily for sucrose concentration from populations formed by crossing a high-sugar line with three previously released germplasm lines that originated from a cross between a cultivated line and a wild B. v. subsp. maritima (L.) Arcang. accession from Greece. The average sucrose concentration of the three germplasm lines was 15 g kg-1 greater than the average of the three cultivated/B. v. subsp. maritima parental lines and 8 g kg-1 less than the average sucrose concentration of a commercial hybrid. The average root yields of F1030, F1031, and F1032 were 54, 75, and 63% of the root yield of a commercial hybrid. The average recoverable sucrose yield of the three germplasm lines was 906 kg ha-1 greater than the average sucrose yield of the three cultivated/B. v. subsp. maritima parents. When used as components in the development of advanced breeding populations, F1030, F1031, and F1032 will contribute to a broadening of the genetic diversity within the commercial sugarbeet crop.
