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.

0GSHO 2506blx3.cHordeum vulgare L. subsp. vulgare Idaho, United States Historic1996DEVELOPEDGenetic materialBlue aleurone color is due to anthocyanin pigments which occur as lumps inside many aleurone granules in some or all aleurone cells. Variation in color expression from dark blue to an off-whit is caused by environmental factors and modifying genes. Aleurone color is best observed in well filled grain that is magnified to show individual aleurone cells, after more superficial tissues have been peeled off. Inheritance: Monofactorial recessive when complementary dominant alleles are present at the Blx1, Blx2, Blx4, and Blx5 loci. Located in chromosome 4HL, close to the blx1 (non-blue aleurone xenia 1) locus, and over 25.3 cM distal from the Kap (hooded lemma) locus. Previous nomenclature and gene symbolization: Non-blue aleurone 3=bl3. Complementary factors for blue vs white aleurone=Bly and bly. Mutational events: blx3.c in line Blx selected from Composite Cross V. Mutant used for description and seed stocks: blx3.c in line Blx selected from Composite Cross V.1545118GSHO 2506

Variaiton in color expression from dark blue to an off-white is caused by environmental factors and modifying genes. Aleurone color is best observed in well filled grain that is magnified to show individual aleurone cells, after more superficial tissues have been peeled off. In heritance: Monofactorial recessive when complementary dominant alleles are present at the Blx2, Blx3, Blx4, and Blx5 loci. Located in chromosome 4HL, over 13.6 cM distal from the glf3 (glossy leaf 3) locus. Previous nomenclature and gene symbolization: Blue aleurone=Bl. Complementary factors for blue vs white aleurone=Bl1 and bl1. Complementary factors for blue vs white aleurone=Blx and blx. Mutational events: blx1.a in Goldfoil (CIho 1866).
