Search
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.

4PI 618620OK 189Medicago sativa L. Oklahoma, United StatesNLGRPNot Available2001DEVELOPEDBreeding materialBroad gene base germplasm descending from hundreds of world collection accessions with little enhancement for adaptation. These populations possess many genes tracing to their highly diverse parentage not normally possessed by most cultivars and experimental strains in traditional breeding programs. In addition to their varying degrees of adaptation contributed by their adapted parent, they provide some resistance to fusarium wilt (Fusarium oxysporum), bacterial wilt (Clavibacter michiganensis), phytophthora root rot (Phytophthora megasperma), anthracnose (Collectotrichum trifolii), blue alfalfa aphid (Acyrthosiphon kondoi) (biotype BAOK90 collected in Oklahoma), and pea aphid (A.
