International Database for Barley Genes and Barley Genetic Stocks
BGS 4, Albino seedling 8, abo8
Stock number: BGS 4
Locus name: Albino seedling 8
Locus symbol: abo8
Previous nomenclature and gene symbolization:
White seedling c2 = ac2 (4).
Albino seedling c2 = ac2 (5).
Albina seedling-m = alb-m (7).
Inheritance:
Monofactorial recessive (2, 4).
Located in chromosome 7HS (1, 3, 6); about 27.2 cM distal from the nud1 (naked caryopsis 1) locus (2); over 11.3 cM distal from the nud1 locus (1); about 18.0 cM distal from the fch8 (chlorina seedling 8) locus (3).
Description:
Seedlings are white in color and devoid of normal pigments (4). Plants with this phenotype are classified as albino mutants (5). The abo8.h gene must be maintained as a heterozygous stock.
