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

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 558513 | FC 401 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | Not Available | 1991 | DEVELOPED | PRE 12/13/1991 | | | | | Breeding material | Diploid self-fertile monogerm O-type (maintainer) of its CMS equivalent FC401CMS. Originated from a cross of ARS O-type sources from disease resistance breeding programs at Fort Collins, CO, and Salinas, CA, followed by selection for cercospora leaf spot resistance and general combining ability. 33% green hypocotyl. Resistance good to leaf spot but little curly top resistance. FC401CMS combines well with AD-3, a high sucrose, tetraploid, Spanish pollinator to produce a triploid hybrid that has high recoverable sucrose production. | 1453485 | PI 558513 |
| 1 | PI 558514 | FC 402 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | | 1991 | DEVELOPED | PRE 12/13/1991 | | | | | Breeding material | Diploid self-fertile monogerm O-type (maintainer) of its CMS equivalent FC402CMS. FC402CMS resulted from hybridization FC603CMS/662119sl, followed by two generations of random pollination by FC402. Resistance good to cercospora leaf spot. 52% green hypocotyl. FC402CMS combines well with AD-1, a multigerm tetraploid pollinator, to produce a triploid hybrid that has high recoverable sucrose and moderate leaf spot resistance. | 1453486 | PI 558514 |
| 2 | PI 558515 | FC 403 | Beta vulgaris L. subsp. vulgaris | Colorado, United States | W6 | | | 1991 | DEVELOPED | PRE 12/13/1991 | | | | | Breeding material | Diploid self-fertile monogerm O-type (maintainer) of its CMS equivalent FC403CMS. Developed from combination of the Fort Collins O-type cercospora resistant line (662119sl) and a Salinas, CA, O-type curly top resistant line (C562), then selected for green hypocotyl. The CMS was from 662119slCMS X C562. Resistance mild to curly top. Susceptible to leaf spot. 100% green hypocotyl. When FC403CMS is hybridized with the highly leaf spot resistant, tetraploid, pollinator, AD-2, the triploid hybrid is leaf spot tolerant and highly productive. | 1453487 | PI 558515 |
