Registration of Seven Sugarbeet Germplasms Selected from Crosses between Cultivated Sugarbeet and Wild Beta Species
- Seven sugarbeet (Beta vulgaris L.) germplasm lines, F1017 (GP-265, PI 656591), F1018 (GP-266, PI 658401), F1019 (GP-267, PI 656592), F1020 (GP-268, PI 656593), F1021 (GP-269, PI 658402), F1022 (GP-270, PI 656594), and F1023 (GP-271, PI 656595), were released 23 Feb. 2009 by the USDA-ARS and the North Dakota Agricultural Experiment Station. These lines were developed to introduce genetic diversity into the narrow base of sugarbeet. The original populations were produced 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. subsp. maritima accessions originally collected in Denmark, Belgium, Ireland, and the Middle East, respectively. The pollinators for F1021, F1022, and F1023 were based on 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 to 122 g kg-1, compared with 136 g kg-1 for a commercial hybrid. These lines will contribute to the broadening of the genetic diversity of the crop, and the infusion of genes from these and other exotic sources may result in unique gene combinations that expand the limits of improvement through selection and enhance combining ability.
