F1030, F1031, and F1032 Sugarbeet Germplasms Selected from Crosses between L19 and Three Cultivated/Wild Germplasms

F1030 (Reg. No. GP‐288, PI 671774), F1031 (Reg. No. GP‐289, PI 671775), and F1032 (Reg. No. GP‐290, PI 671776) sugarbeet, Beta vulgaris subsp. v ulgaris (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. vulgaris 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. vulgaris 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. vulgaris 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.
