Interpretive Summary: FC305 sugarbeet germplasm was released and developed by the USDA-ARS, at Fort Collins, CO, Salinas, CA, and East Lansing, MI, in cooperation with the Beet Sugar Development Foundation, Denver, CO. This germplasm is a diploid, multigerm sugarbeet population in normal cytoplasm, with variation for self-sterility (some self-fertile) , multigermity (both monogerm and multigerm), and hypocotyl color (red, pink, green). FC305 has resistance to fusarium yellows , moderate resistance to cercospora leaf spot (CLS), aphanomyces root rot and beet curly top. This germplasm has some genes for resistance to rhizomania, containing both Rz1 and Rz2 genes for resistance but not in100% of the plants. There was no resistance to strains of rhizoctonia crown and root. This germplasm provides an alternate source of resistance to CLS and fusarium yellows in a diverse genetic background to enrich the cultivated sugarbeet germplasm base. FC305 provides a source population from which to select disease-resistant, multigerm pollinator parents. Because monogerm and O-type is within its parentage, it should be possible to select monogerm, O-type lines from this germplasms as well.

Technical Abstract: FC305 (PI 671963) sugarbeet germplasm (Beta vulgaris L.) was released and developed by the USDA-ARS, at Fort Collins, CO, Salinas, CA, and East Lansing, MI, in cooperation with the Beet Sugar Development Foundation Denver, CO. This germplasm is a diploid multigerm sugarbeet population in normal cytoplasm, segregating for self-sterility (Sf:SsSs), multigermity (M:mm), and hypocotyl color (R:rr). FC305 has resistance to fusarium yellows (Fusarium oxysporum Schlecht. f. sp. betae (Stewart) Snyd. & Hans.), moderate resistance to cercospora leaf spot (CLS) (Cercospora beticola Sacc.), aphanomyces root rot (Aphanomyces cochlioides Drechsl.) and beet curly top (BCT) (Beet curly top virus). This germplasm is segregating for resistance to rhizomania (Beet necrotic yellow vein virus) and contains both Rz1 and Rz2 genes for resistance. There was no resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kühn. This germplasm provides an alternate source of resistance to CLS and fusarium yellows in a diverse genetic background to enrich the cultivated sugarbeet germplasm base. FC305 provides a source from which to select disease-resistant, multigerm pollinator parents. Because monogerm and O-type is within its parentage, it should be possible to select monogerm, O-type, CMS-maintainer lines from this germplasms as well.
