BGN  26:146 Export to PDF
Stock number: BGS 112
Locus name: Albino seedling 9
Locus symbol: abo9

Previous nomenclature and gene symbolization:

White seedling n = an (2).
Albino seedling n = an (3).

Inheritance:

Monofactorial recessive (2).
Located in chromosome 3HS (1, 2); abo9.i is about 9.4 cM distal from the xnt3 (xantha seedling 3) locus (2); abo9.i is about 15.5 cM proximal from the xnt6 (xantha seedling 6) locus (2); about 9.9 cM distal from the yst1 (yellow streak 1) locus (1).

Description:

Seedlings are white in color and devoid of normal pigments (2). Plants with this phenotype are classified as albino mutants (3). The abo9.i gene must be maintained as a heterozygous stock.

Origin of mutant:

A spontaneous mutant in Hordeum distichum var nigrinudum (2).

Mutational events:

abo9.i (Nigrinudum I, GSHO 348) in Nigrinudum (NSL 3286, GSHO 988) (2).

Mutant used for description and seed stocks:

abo9.i (GSHO 348) in Nigrinudum.
