BGS 341, Albino seedling 12, abo12

BGN  26:290
Stock number: BGS 341
Locus name: Albino seedling 12
Locus symbol: abo12

Previous nomenclature and gene symbolization:

Albino seedling c = alb,,c (1).
Albino seedling o = alb,,o (2).


Monofactorial recessive (1, 2).
Located in chromosome 5HS (2); abo12.o is over 26.1 cM distal from the msg16 (male sterile genetic 16) locus (2); abo12.o is not linked to the msg19 (male sterile genetic 19) locus (2).


Seedlings have a white color and die at the two to three leaf stage (1). The abo12.o gene must be maintained as a heterozygous stock.

Origin of mutant:

A spontaneous mutant in Titan (CIho 7055) (1).

Mutational events:

abo12.o (GSHO 583) in Titan (CIho 7055) (1, 2).

Mutant used for description and seed stocks:

abo12.o (GSHO 583) in Titan.
