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.

| 0 | PI 628656 | UCRTCL1-2001 | ×Triticosecale sp. | California, United States | NSGC |  | | 2001 | DEVELOPED | | | | | | Breeding material | Hexaploid winter triticale cv Presto with an engineered rye chromosome 1R that has an intercalary insert of 1DL in its long arm. This insert introduces wheat locus Glu-D1 encoding high molecular weight glutenin subunits 5+10 and replaces a corresponding rye segment with secalin locus Sec-3. This translocated chromosome 1R improves breadmaking quality of triticale up to 200% depending on the background. | 1631439 | PI 628656 |
| 1 | PI 628657 | UCRTCL2-2001 | ×Triticosecale sp. | California, United States | NSGC |  | | 2001 | DEVELOPED | | | | | | Breeding material | Hexaploid winter triticale cv Presto with an engineered rye chromosome 1R Valdy. Chromosome Valdy has an intercalary insert of 1DL in its long arm that introduces wheat locus Glu-D1 encoding high molecular weight glutenin subunits 5+10, replacing a corresponding rye segment with secalin locus Sec-3. On the short arm chromosome Valdy carries translocation WR-4 that introduces a segment of wheat chromosome 1DS with the Gli-D1 and Glu-D3 loci present. Sec-1 locus of rye remains. This translocated chromosome 1R improves breadmaking quality of triticale by up to 256%, depending on the background. | 1631440 | PI 628657 |
| 2 | PI 628658 | UCRTCL3-2001 | ×Triticosecale sp. | California, United States | NSGC |  | | 2001 | DEVELOPED | | | | | | Breeding material | Hexaploid winter triticale cv Presto with cytogenetically engineered chromosomes 1A and 1R. Chromosome 1R is the translocation Valdy, with a intercalary segment of 1DL 1A and 1R. Chromosome 1R is the translocation Valdy, with a intercalary segment of 1DL on the long arm and translocaton QR4 on the short arm. The 1DL segment introduces wheat locus Glu-D1 and removes rye locus Sec-3; WR4 introduces wheat loci Glu-D1 and Glu-D3; rye locus Sec-1 remains. Chromosome 1A has in its long arm an intercalary insert from chromosome 1DL that carries locus Glu-D1 and replaces Glu-A1. This line has four doses of Glu-D1 (on 1A and 1R) which in both cases encodes high molecular weight glutenin subunits 5+10. The translocations significantly improves breadmaking quality of triticale. | 1631441 | PI 628658 |
