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 657938 | CN72-652 | Beta vulgaris L. subsp. vulgaris | California, United States | W6 | | Not Available | 2009 | DEVELOPED | PRE 08/12/2009 | | | | | Breeding material | CN72-652 is a S2 line tested in the Imperial Valley, CA. It gave fair sugar yield with characteristic low percent sucrose. In the Imperial Valley, it had a sugarbeet cyst nematode canopy score of 3.0 (moderately susceptible), but in the greenhouse tests had low cyst counts and appeared to by homozygous sugarbeet cyst nematode resistant. | 1812157 | PI 657938 |
| 1 | PI 657939 | CN12-446 | Beta vulgaris L. subsp. vulgaris | California, United States | W6 | | Not Available | 2009 | DEVELOPED | PRE 08/12/2009 | | | | | Breeding material | CN12-446 may be homozygous resistant to sugarbeet cyst nematode. It is the second increase of composites from S3 progenies derived from CN12 (PI 636338). CN12-446 is nematode resistant (from WB 242), powdery mildew resistant (from WB 242), and rhizomania resistant (from Rz1). It appears to have resistance/tolerance to Empoasca/mites in the Imperial Valley, CA giving it a stay-green canopy. It has a compact, attractive, dark green canopy. | 1812158 | PI 657939 |
| 2 | PI 657940 | CN12-770 | Beta vulgaris L. subsp. vulgaris | California, United States | W6 | | Not Available | 2009 | DEVELOPED | PRE 08/12/2009 | | | | | Breeding material | CN12-770 is a S3 line tested in the Imperial Valley, CA. It gave the highest percent sucrose and sugar yield with 0% bolting and a very resistant sugarbeet cyst nematode canopy score. It appears to be resistant to Empoasca and/or mites, giving it a stay-green canopy due to its resistance to sugarbeet cyst nematode and powdery mildew resistance. | 1812159 | PI 657940 |
