(Results of more than 500 will not return images.)
This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as
PI 651794
PI 651649
PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.
The more information you provide, the better the search will be.

| 0 | PI 574627 | FC 716 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | | 1993 | DEVELOPED | PRE 12/03/1993 | | | | | Breeding material | Diploid, multigerm, easy bolting, medium sucrose content, and 88% green hypocotyls. All plants have the cytoplasmic factor for male sterility (CMS) but segregate about 80% pollen fertile (non-O-type) and 20% CMS. Good pollen producer. Low frequency of segregants for monogerm and O-type. Potential source of resistant pollinators with high combining ability. Excellent Rhizoctonia (R. solani AG-2-2) root rot resistance when tested under strong disease pressure. Low-medium leaf spot (Cercospora beticola) resistance and susceptible to curly top virus | 1469598 | PI 574627 |
| 1 | PI 574628 | FC 717 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | | 1993 | DEVELOPED | PRE 12/03/1993 | | | | | Breeding material | Diploid, multigerm, medium sucrose, and 17% green hypocotyls. Low frequency of monogerm and O-type segregants, normal cytoplasm, and good pollen producer. No combining ability data, but has potential as a source for selection of high combining, resistant pollinators. Excellent Rhizoctonia (R. solani AG-2-2) root rot resistance when tested under strong disease pressure. Low-medium leaf spot (Cercospora beticola) resistance and susceptible to curly top virus | 1469599 | PI 574628 |
| 2 | PI 574629 | FC 718 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | Not Available | 1993 | DEVELOPED | PRE 12/03/1993 | | | | | Breeding material | Diploid, multigerm, low sucrose, and 27% green hypocotyls. Vigorous and heterogeneous. Potential source of high combining, resistant pollinators. Excellent Rhizoctonia (R. solani Ag-2-2) root rot resistance when tested under strong disease pressure. Unrelated to any other FC releases, but the resistance appears to be quantitative and reacts with the pathogen in the same manner as resistant germplasm from U.S. sources. Susceptible to leaf spot (Cercospora beticola) and curly top | 1469600 | PI 574629 |
| 3 | PI 574630 | FC 719 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | Not Available | 1993 | DEVELOPED | PRE 12/03/1993 | | | | | Breeding material | Diploid, multigerm, high sucrose, and 71% green hypocotyls. Because half the genes in the source were from a high sucrose Polish population unrelated to any U.S. germplasm, should have some genetic diversity and potential to yield high-combining, resistant pollinators. Excellent Rhizoctonia (R. solani AG-2-2) root rot resistance when tested under strong disease pressure. Little resistance to leaf spot (Cercospora beticola) or curly top | 1469601 | PI 574630 |
