BGS 63, Virescent seedling 1, yvs1

BGN  26:99
Stock number: BGS 63
Locus name: Virescent seedling 1
Locus symbol: yvs1

Previous nomenclature and gene symbolization:

Yellow seedling 1 = y (1, 3).
Xantha (yellow) seedling x = yx (5).
Yellow seedling x = yx (4).
Albina seedling-c = alb-c (9).


Monofactorial recessive (1, 6, 7).
Located in chromosome 2HS (5); yvs1.a is over 13.7 cM proximal from the fch15 (chlorina seedling 15) locus (2, 6); yvs1.a is about 2.0 cM proximal from the fch1 (chlorina seedling 1) locus (2, 6).


Virescent seedlings have a slightly green tip, but fail to survive beyond the seedling stage (5, 7). Recessive alleles at the yvs1 locus must be maintained as heterozygous stocks.

Origin of mutant:

A spontaneous mutant in a Swedish cultivar (1, 7).

Mutational events:

yvs1.a (GSHO 68) in a Swedish cultivar (1, 6); yvs1.b (yx) (GSHO 62) in Faust I (CIho 4579) (5); alb-c.7 (NGB 14684) in Gull (NGB 1480, CIho 1145) (8, 9, 10).

Mutant used for description and seed stocks:

yvs1.a (GSHO 68) in Minn 72-8.
