Select the tab for the type of search. Each tab has everything you need to do to perform that type of search.

(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.

0PI 682085'R21'Beta vulgaris L. W6Not Available2017Breeding materialR21 is a multigerm (MM), self-sterile (Ss), open-pollinated line that maintains sugar and root yields under both the wild-type (Type A) and Rz1 resistance-breaking (Type-A, IV) strains of BNYVV. It is a product of repeated rounds of recurrent selection on enhanced, broadly based populations of over 120 Beta vulgaris subsp. maritima accessions (selected for rhizomania resistance) crossed with sugar beet. This broadly-based germplasm provides useful genetic variability for continued sugar beet improvement.1949921PI 682085
