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).
Albino seedling a = alb,,a (1).
Xantha seedling g = xan,,g (2).
Inheritance:
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).
Located in chromosome 1HL (2); xnt7.g is about 2.0 cM from the msg1 (male sterile genetic 1) locus (2).
Description:
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.
