| 0 | PI 658059 | FC1018 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | | 2009 | DEVELOPED | PRE 09/23/2009 | | | | | Breeding material | FC1018 sugarbeet germplasm is a multigerm sugarbeet population in a fertile cytoplasm, segregating for self-sterility and hypocotyl color. It has good resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani K hn and carries the Rz1 gene, which confers resistance to some strains of Beet necrotic yellow vein virus, the causal agent of rhizomania. FC1018 shows a moderate tolerance to cercospora leaf spot, caused by Cercospora beticola Sacc., to Beet curly top virus, and to Aphanomyces cochlioides Drechsl., which causes aphanomyces root rot (aphanomyces black root). FC1018 has shown favorable yield characteristics when evaluated as a line and a pollinator in experimental hybrids in two trials grown under rhizomania conditions at Salinas in 2006. It is a population from which to select disease-resistant, multigerm pollinator parents. | 1813918 | PI 658059 |

It carries the Rz1 gene, which confers resistance to some strains of Beet necrotic yellow vein virus, the causal agent of rhizomania. It has moderate resistance to cercospora leaf spot, caused by Cercospora beticola Sacc., to Beet curly top virus, to rhizoctonia root and crown rot, caused by Rhizoctonia solani K hn, and to Aphanomyces cochlioides Drechsl., which causes aphanomyces root rot (aphanomyces black root). FC1020 has good field performance for percentage sucrose. It is a population from which to select disease-resistant, multigerm pollinator parents. | 1813920 | PI 658061 |

It carries the Rz1 gene, which confers resistance to some strains of Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. It showed a moderate tolerance to Beet curly top virus. FC1022 has moderate susceptibility to cercospora leaf spot, caused by Cercospora beticola Sacc., to Aphanomyces cochlioides Drechsl., which causes aphanomyces root rot (aphanomyces black root) and to root-rotting strains (AG-2-2) of Rhizoctonia solani K hn. When tested at Salinas, CA, under rhizomania conditions, FC1022 had a good percent sucrose. It is a population from which to select disease-resistant, multigerm pollinator parents, and, because of a large percent monogerm (45%) seedballs and O-type parentage, it should be possible to selected monogerm, O-type female maintainer lines. | 1813921 | PI 658062 |
