Interpretive Summary: ‘FC1018’, ‘FC1019’, ‘FC1020’, and ‘FC1022’ sugarbeet germplasms were released in 2009. They were developed by the USDA-ARS, at Fort Collins, CO, and at Salinas, CA, in cooperation with the Beet Sugar Development Foundation (BSDF), Denver, CO. All four germplasms are multigerm sugarbeet populations in fertile cytoplasm, segregating for self-sterility, multigermity, hypocotyl color and resistance to some strains of rhizomania. FC1018, FC1019, and FC1020 show some tolerance to rhizoctonia root rot, cercospora leaf spot, beet curly top virus, and aphanomyces root rot (aphanomyces black root). They are populations from which to select disease-resistant, multigerm pollinator parents. FC1022 showed a moderate tolerance to beet curly top, and had good sucrose content when tested at Salinas, CA, under rhizomania conditions. Because of a large percent monogerm seedballs and O-type parentage, it should be possible to select monogerm, O-type, CMS maintainer lines from FC1022.

Technical Abstract: ‘FC1018’, ‘FC1019’, ‘FC1020’, and ‘FC1022’ (PI 658059, PI 658060, PI 658061, PI 658062, respectively) sugarbeet germplasm (Beta vulgaris L.) were released in 2009 from 05-FC1018, 05-FC1019, 07-/08-FC1020 and 05-FC101022 seed lots, respectively, and tested under those designations. They were developed by the USDA-ARS, at Fort Collins, CO, and at Salinas, CA, in cooperation with the Beet Sugar Development Foundation (BSDF), Denver, CO. All four germplasms are multigerm sugarbeet populations in fertile cytoplasm, segregating for self-sterility, multigermity, hypocotyl color and the Rz1 gene, which confers resistance to some strains of Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. FC1018, FC1019, and FC1020 show some tolerance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kühn, cercospora leaf spot (CLS), caused by Cercospora beticola Sacc., Beet curly top virus (BCTV), and Aphanomyces cochlioides Drechsl., which causes aphanomyces root rot (aphanomyces black root). They are populations from which to select disease-resistant, multigerm pollinator parents. FC1022 showed a moderate tolerance to BCTV, and had good sucrose content when tested at Salinas, CA, under rhizomania conditions. Because of a large percent monogerm (45%) seedballs and O-type parentage, it should be possible to select monogerm, O-type, CMS maintainer lines from FC1022.
