BGS 106, Albino seedling 6, abo6

BGN  46:60
Stock number: BGS 106
Locus name: Albino seedling 6
Locus symbol: abo6

Previous nomenclature and gene symbolization:

White seedling c = ac (2).
Albino seedling c = ac (3).


Monofactorial recessive (2).
Located in chromosome 3HS (4); abo6.f is about 10.7 cM distal from the uzu1 (uzu 1) locus (4); abo6.f is about 2.4 cM from the msg5 (male sterile genetic 5) locus (1).


Seedlings are white in color, devoid of normal pigments, and die about 10 days after emergence (2). Plants with this phenotype are classified as albino mutants (3). The abo6.f gene must be maintained as a heterozygous stock.

Origin of mutant:

A spontaneous mutant in Colsess (CIho 2792) (2).

Mutational events:

abo6.f (Colsess III, GSHO 63) in Colsess (CIho 2792) (2); Colsess I (GSHO 30) and Colsess II in Colsess (2).

Mutant used for description and seed stocks:

abo6.f (GSHO 30, Colsess I) in Colsess (CIho 2792).
