BGS 3, Virescent seedling 2, yvs2

BGN  26:46
Stock number: BGS 3
Locus name: Virescent seedling 2
Locus symbol: yvs2

Previous nomenclature and gene symbolization:

Virescent seedling-c = yc (2).


Monofactorial recessive (1).
Located in chromosome 7HS (2); about 24.4 cM proximal from the gsh3 (glossy sheath 3) locus (3); 17.0 cM distal from the cer-f (eceriferum-f) locus (3).


The seedling leaf is white with a very marked green tip, which remains green. The green area on the second leaf is very small or lacking. Homozygous recessive seedlings seldom survive beyond the two leaf stage (1). The yvs2.c gene is generally maintained as a heterozygous stock.

Origin of mutant:

A spontaneous mutant in Coast (PI 539103) (1).

Mutational events:

yvs2.c (GSHO 41, Coast III) in Coast (PI 539103) (1).

Mutant used for description and seed stocks:

yvs2.c (GSHO 41) in Coast.
