BGS 233, Xantha seedling 7, xnt7

BGN  26:231
Stock number: BGS 233
Locus name: Xantha seedling 7
Locus symbol: xnt7

Previous nomenclature and gene symbolization:

Xantha seedling 66 = x66 (1).
Albino seedling a = alb,,a (1).
Xantha seedling g = xan,,g (2).


Monofactorial recessive (1, 2).
Located in chromosome 1HL (2); xnt7.g is about 2.0 cM from the msg1 (male sterile genetic 1) locus (2).


Seedlings have a yellow color and die at the two to three leaf stage (1). The xnt7.g gene must be maintained as a heterozygous stock.

Origin of mutant:

A spontaneous mutant in Erbet (CIho 13826) (1).

Mutational events:

xnt7.g (GSHO 581) in Erbet (GSHO 2475) (1).

Mutant used for description and seed stocks:

xnt7.g (GSHO 581) in Erbet.
