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 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 658654F1024Beta vulgaris L. subsp. vulgaris North Dakota, United StatesW62010DEVELOPEDPRE 02/17/2010Breeding materialRoots of F1024 are white, tapered, and un-branched with a relative shallow groove. The roots are larger and longer than those of F1016, its sugarbeet root maggot (Tetanops myopaeformis R der) resistant parent, and F1024 plants are generally larger and more vigorous than those of F1016. The root maggot resistance of F1024 is equal to or slightly better than that of F1016. Very little root maggot feeding is observed on F1024, even at lower depths where maggot damage is often the most prevalent on susceptible genotypes. F1024 has moderate resistance to Cercospora leaf spot (Cercospora beticola), a foliar disease of world-wide importance. Testcrosses with susceptible female lines had approximately one percent less sugar, higher root and recoverable sugar yields, and substantially less root maggot damage than otherwise adapted root maggot susceptible hybrids, when evaluated with no insecticide at sites with root maggot present. 1831238PI 658654
