BGS 105, Xantha seedling 3, xnt3
Stock number: BGS 105
Locus name: Xantha seedling 3
Locus symbol: xnt3
Previous nomenclature and gene symbolization:
Xantha seedling c = xc (1).
Viridis seedling-l = vir-l (3).
Viridis seedling-l = vir-l (3).
Inheritance:
Monofactorial recessive (1).
Located in chromosome 3HS (5, 6); xnt3.c is about 9.4 cM proximal from the abo9 (albino seedling 9) locus (2); xnt3.c is about 14.4 cM distal from the uzu1 (uzu 1) locus (5, 6); xnt3.c is about 3.7 cM proximal from the alm1 (albino lemma 1) locus (5).

Description:
Seedlings have a yellow (picric yellow) to yellow-green color depending upon temperatures, but they can be grown to maturity under certain environmental conditions (1). The xnt3.c gene must be maintained as a heterozygous stock.
