Sugarbeet ( Beta vulgaris L.) germplasms EL54 (Reg. No. GP‐277, PI 654357) and EL55 (Reg. No. GP‐278, PI 655304) were released to increase the available germplasm base of sugarbeet and were developed by the USDA‐ARS, at East Lansing, MI in cooperation with the Beet Sugar Development Foundation, Denver, CO and the Michigan Agricultural Experiment Station. EL54 is being released in the interest of broadening the genetic base of sugarbeet; the specific goal of this release was to improve root traits, via mother‐root selection, relative to the wild species [ B. vulgaris L. subsp. maritima (L.) Arcang.] to the point of commercial potential. The progenitors of EL54 were WB879, a wild species reported with exceptional resistance to diseases caused by Aphanomyces cochlioides Drechs., and sugarbeet germplasms SP6822 and C869, each with good agronomic performance for eastern and western U.S. growing areas, respectively. EL55 is being released for its potential seed storability; it was selected via mother‐root selection from legacy USDA‐ARS (East Lansing, MI) seed lots that were grown in the field directly after long‐term (>15 yr) seed storage under high ambient humidity. EL55 may provide traits that contribute to long‐term viability of hybrid and nonhybrid sugarbeet seed.
