BGS 113, Xantha seedling 6, xnt6

BGN  26:147
Stock number: BGS 113
Locus name: Xantha seedling 6
Locus symbol: xnt6

Previous nomenclature and gene symbolization:

Xantha seedling s = xs (2).


Monofactorial recessive (2).
Located in chromosome 3HS (2); xnt6.f is over 15.5 cM distal from the abo9 (albino seedling 9) locus (2); xnt6.f is over 15.3 cM distal from the msg5 (male sterile genetic 5) locus (1) and over 22.0 cM distal from the wst1 (white streak 1) locus (3).


Seedlings have a bright yellow (citron green) to yellow-green color and do not survive beyond the seedling stage (2). The xnt6.f gene must be maintained as a heterozygous stock.

Origin of mutant:

A spontaneous mutant in Smyrna (PI 7969) (2).

Mutational events:

xnt6.f (xs) (Smyrna I, GSHO 117) in Smyrna (PI 7969) (2).

Mutant used for description and seed stocks:

xnt6.f (GSHO 117) in Smyrna.
