BGS 4, Albino seedling 8, abo8

BGN  26:47
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).


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).


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.
