Interpretive Summary: Seven sugarbeet germplasm lines, F1017, F1018, F1019, F1020, F1021, F1022, and F1023 were released 23 February 2009 by the USDA-ARS and the North Dakota Agricultural Experiment Station. The genetic variability of the current sugarbeet crop is limited. Broadening the genetic diversity within the commercial crop may prevent devastating epidemics and provide a base for future improvements in productivity. These lines were developed with the intent of introducing diversity into the narrow genetic base of sugarbeet. The original populations were formed by crossing a cultivated line with wild relatives of sugarbeet. The pollinators for F1017, F1018, F1019, and F1020 were Beta vulgaris. spp. maritima accessions originally collected in Denmark, Belgium, Ireland, and the Middle East, respectively. The pollinators for F1021, F1022, and F1023 were based upon species (F1021, Beta atriplicifolia; F1022, Beta macrocarpa; F1023, Beta patula). Six-year mean root yield of the germplasm lines was 14.6 tons per acre or 63% of the yield of an adapted hybrid. Average sucrose concentrations of the lines ranged from 11.4 % to 12.2%, compared to 13.6% for a commercial hybrid.

Technical Abstract: Seven sugarbeet (Beta vulgaris L.) germplasm lines, F1017 (GP-xxx, PIxxxxxx), F1018 (GP-xxx, PIxxxxxx), F1019 (GP-xxx, PIxxxxxx), F1020 (GP-xxx, PIxxxxxx), F1021 (GP-xxx, PIxxxxxx), F1022 (GP-xxx, PIxxxxxx), and F1023 (GP-xxx, PIxxxxxx) were released 23 February 2009 by the USDA-ARS and the North Dakota Agricultural Experiment Station. These lines were developed with the intent of introducing diversity into the narrow genetic base of sugarbeet. The original populations were formed by crossing male-sterile plants of a cultivated line with wild relatives of sugarbeet. The pollinators for F1017, F1018, F1019, and F1020 were B. v. spp. maritima accessions originally collected in Denmark, Belgium, Ireland, and the Middle East, respectively. The pollinators for F1021, F1022, and F1023 were based upon species (F1021, B. atriplicifolia Rouy; F1022, B. macrocarpa Guss.; F1023, B. patula Aiton). Six-year mean root yield of the germplasm lines was 32.63 Mg ha-1 or 63% of the yield of an adapted hybrid. Average sucrose concentrations of the lines ranged from 114 g kg-1 to 122 g kg-1, compared to 136 g kg-1 for a commercial hybrid.
