FC1018 (Reg. No. GP-273, PI 658059), FC1019 (Reg. No. GP-274, PI 658060), FC1020 (Reg. No. GP-275, PI 658061), and FC1022 (Reg. No. GP-276, PI 658062) sugarbeet (Beta vulgaris L.) germplasms were released in 2009 from seed lots 05-FC1018; 05-FC1019; 07-, 08-, or 09-FC1020; and 05-FC1022, respectively, and tested under those designations. They were developed by the USDA-ARS at Fort Collins, CO and Salinas, CA in cooperation with the Beet Sugar Development Foundation, Denver, CO. All four germplasms are populations in fertile cytoplasm and segregate for self-sterility, multigermity, hypocotyl color, and the Rz1 gene, which confers resistance to some strains of Beet necrotic yellow vein virus, the causal agent of rhizomania. FC1018, FC1019, and FC1020 have moderate tolerance to root-rotting strains (AG-2–2) of Rhizoctonia solani Kühn (the causal agent of Rhizoctonia root and crown rot), Cercospora beticola Sacc. (the causal agent of Cercospora leaf spot), Beet curly top virus (BCTV), and Aphanomyces cochlioides Drechsl., which causes Aphanomyces root rot (Aphanomyces black root). They are populations that can be used to select disease-resistant, multigerm pollinator parents. FC1022 has a moderate tolerance to BCTV and had a relatively high sucrose concentration at Salinas when tested in a field infested with rhizomania. Because of a large percentage of monogerm seedballs (45%) and O-type parentage, it should be possible to select monogerm, O-type lines from FC1022.
