BGS 37, Xantha seedling 9, xnt9
Stock number: BGS 37
Locus name: Xantha seedling 9
Locus symbol: xnt9
Previous nomenclature and gene symbolization:
Albino seedling d = alb,,d (1).
Xantha seedling i = xan,,i (2).
Inheritance:
Monofactorial recessive (1, 2).
Located in chromosome 7HL (2); xnt9.i is over 7.4 cM from the msg23 (male sterile genetic 23) locus (2).
Description:
Seedlings have a yellow color and die at the two to three leaf stage (1). The xnt9.i gene must be maintained as a heterozygous stock.
