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.

The initial cross was made in 1991. A set of 180 lines were tested for adult plant resistance to powdery mildew (APR-PM), as F2:3 lines in 1994 and as F5:6, F6:7, F7:8 headrows in 1997, 1998 and 1999. Three quantitative trait loci for APR-PM were mapped onto chromosomes 1A, 2A, and 2B. A set of 152 F7:14 RILs were tested for Fusarium head blight (FHB) resistance, in greenhouse experiments in 2007 and 2008 and field FHB nurseries in 2008 and 2009. Consistent QTL for FHB resistance were mapped on to chromosomes 3BL, 4BS and 4DS. The 2 parents of Becker/Massey Mapping Population have been assigned new PI numbers to reflect their association with the Mapping population: `Becker?, PI 494524, newly assigned PI 664480 map and `Massey?, CItr 17953, newly assigned PI 664481map.1897577NSL 479730 MAP
