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 107fch2.cHordeum vulgare L. subsp. vulgare Colorado, United StatesNSGCKERNELS1994DONATED05/1994Genetic materialSeedlings have a pale yellow-green color, which persists until near maturity under greenhouse or field conditions. Development of homozygous is delayed, but the stunted plants survive to produce seed. A complete absence or greatly reduced levels of chlorophyll b were found in mutant plants. Respiratory and photosynthetic rates of detached leaves and intact plants were not significantly different from those of normal plants. However, the growth rate of mutant plants decreased after the endosperm was depleted. An absence of chlorophyll b-binding proteins in the photosynthetic membranes was found in fch2 mutants. Inheritance: Monofactorial recessive. Located in chromosome 3HL, about 7.7 cM distal from the cur2 (curly 2) locus. Previous nomenclature and gene symbolization: Chlorina seedling 2=f2. Light green 5=lg5. Chlorina seedling f2=clo-f2. Mutational events: fch2.c in 28-3398 Chlorina; fch2.y (lg5) in CIho 6151; clo-f2.2800, -f2.2807, -f2.3613 in Donaria (PI 209784), -f2.101, -f2.102, -f2.103, -f2.105, -f2.107, -f2.108, -f2.109 in Tron, -f2.122, -f2.123, -f2.133 in Bonus (PI 189763). Mutant used for description and seed stocks: fch2.c in 28-3398 (GSHO 107); fch2.c in Bowman (PI 483237)*7 (GSHO 1993).1510706GSHO 107
1GSHO 4fch7.hHordeum vulgare L. subsp. vulgare Colorado, United StatesNSGCKERNELS1994DEVELOPEDGenetic materialSeedlings are light green and remain light green until near maturity. Plant vigor and seed yield are reduced, and developmental stages are delayed. Inheritance: Monofactorial recessive. Located in chromosome 1HL, about 4.7 cM proximal from the trd (third outer glume) locus, and about 22.7 cM distal from the Blp (black lemma and pericarp) locus. Previous nomenclature and gene symbolization: Chlorina seedling 7=f7. Chlorina seedling 7=clo-f7f7. Mutational events: fch7.h in Smyrna (Smyrna II; fch7.h in Smyrna (Smyrna III). Mutant used for description and seed stocks: fch7.h in Smyrna (GSHO 4); fch7.h in Bowman (PI 483237)*7 (GSHO 2058).1510817GSHO 4
2GSHO 68yvs1.aHordeum vulgare L. subsp. vulgare Colorado, United StatesNSGCKERNELS1994DONATED05/1994Genetic materialVirescent seedlings have a slightly green tip, but fail to survive beyond the seedling stage. Recessive alleles at the yvs1 locus must be maintained as heterozygous stocks. Inheritance: Monofactorial recessive. Located in chromosome 2HS, over 13.7 cM proximal from the fch15 (chlorina seedling 15) locus and about 2.0 cM proximal from the fch1 (chlorina seedling 1) locus. Previous nomenclature and gene symbolization: Yellow seedling 1=y. Xantha (yellow) seedling x=yx. Yellow seedling x=yx. Albino seedling-c=alb-c. Mutational events: yvs1.a in a Swedish cultivar; yvs1.b (yx)(GSHO 62) in Faust I (CIho 4579); alb-c.7 in Gull (CIho 1145). Mutant used for description and seed stocks: yvs1.a in Minn 72-8 (GSHO 68).1510837GSHO 68
