Interpretive Summary: Sodium, potassium, and amino-nitrogen are naturally occurring constituents of sugarbeet roots, referred to as impurities, which prevent processors from extracting a portion of the sugar in the root. F1025, F1026, and F1027 sugarbeet germplasm lines, selected for low concentrations of sodium, potassium, and amino-nitrogen, respectively, in the roots, were released by the USDA-ARS and the North Dakota Agricultural Experiment Station, North Dakota State University, Fargo, ND. F1025, F1026, and F1027 were selected from a common parental population formed by crossing a breeding line with plants from a heterogeneous population that included some wild relatives of sugarbeet in its parentage. The sodium concentration of F1025 was 57% of the average sodium concentration of the parental population; the average potassium concentration of F1026 was 73% of the potassium concentration of the parental population; and the amino-nitrogen concentration of F1027 was 76% of the parental population. Compared to the parental population, sodium concentration increased 11% and potassium concentration decreased 6% in conjunction with the decreased amino-nitrogen concentration of F1027. Selection for low sodium or potassium concentration did not affect the other two impurity components. The average sugar concentration of F1025 exceeded that of the parental population by 0.4 %. Selecting for low potassium or amino-nitrogen concentration had no affect on sugar concentration.

Technical Abstract: F1025 (Reg. No. GP-xxx, PI xxxxxx), F1026 (Reg. No. GP-xxx, PI xxxxxx), and F1027 (Reg. No. GP-xxx, PI xxxxxx) sugarbeet (Beta vulgaris L.) germplasm lines, selected for low concentrations of sodium, potassium, and amino-nitrogen, respectively, in the roots, were released by the USDA-ARS and the North Dakota Agricultural Experiment Station, North Dakota State University, Fargo, ND on 29 August 2011. Sodium, potassium, and amino-nitrogen are naturally occurring constituents of sugarbeet roots that prevent processors from extracting a portion of the sucrose in the root. F1025, F1026, and F1027 were selected from a common parental population formed by crossing a cytoplasmic male-sterile monogerm breeding line with plants from a heterogeneous multigerm population that included some B. maritima L. in its parentage. The eight-year average sodium concentration of F1025 was 57% of the average sodium concentration of the parental population; the average potassium concentration of F1026 was 73% of the potassium concentration of the parental population; and the amino-nitrogen concentration of F1027 was 76% of the parental population. Compared to the parental population, sodium concentration increased 11% and potassium concentration decreased 6% in conjunction with the decreased amino-nitrogen concentration of F1027. Selection for low sodium or potassium concentration did not affect the other two impurity components. The average sucrose concentration of F1025 exceeded that of the parental population by 4 g kg-1. Selecting for low potassium or amino-nitrogen concentration had no affect on sucrose concentration.
