Interpretive Summary: FC201 is population of sugarbeet with to rhizomania. It has some resistance to Rhizoctonia root-rot and to the sugar beet root aphid, as well as moderate resistance to cercospora leaf spot, black root and to Beet curly top virus. FC201 is a heterogeneous population from which to select disease resistant monogerm, O-type parents to infuse multiple disease resistance on the female side of hybrids. There is no CMS equivalent. FC201 is released from Salinas seed production 01-FC1014 and has been tested as 00-FC1014 and 01-FC1014. FC201 is an O-type germplasm with 94% red hypocotyl color and 90% monogerm seed.

Technical Abstract: FC201 is a segregating population of sugarbeet (Beta vulgaris L.) with a high frequency of the Rz allele conferring resistance to rhizomania caused by Beet necrotic yellow vein virus. It is segregating for resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kühn and to the sugar beet root aphid (Pemphigus sp.), has moderate resistance to cercospora leaf spot caused by Cercospora beticola Sacc., to black root caused by Aphanomyces cochlioides Drechsl., and the Beet curly top virus. FC201 is a heterogeneous population from which to select disease resistant monogerm, O-type parents to infuse multiple disease resistance on the female side of hybrids. There is no CMS equivalent. FC201 is released from Salinas seed production 01-FC1014 and has been tested as 00-FC1014 and 01-FC1014. FC201 is an O-type germplasm with 94% red hypocotyl (68 plants counted) color (R) and 90% monogerm seed (mm).
