BGS 589, Albino seedling 11, abo11

BGN  26:516
Stock number: BGS 589
Locus name: Albino seedling 11
Locus symbol: abo11

Previous nomenclature and gene symbolization:

Albino seedling t = albt (1).
Albino seedling t3 = at3 (3).


Monofactorial recessive (1, 2).
Location is unknown.


Seedlings are albino when grown under low temperature conditions (below 7.5ºC), but normal green under high temperature conditions (above 18.5ºC). Failure to produce chlorophyll seems confined to early seedling stages (2).

Origin of mutant:

A spontaneous mutant in Trebi (PI 537442) (2, 3).

Mutational events:

abo11.k (Trebi II, GSHO 233) in Trebi (PI 537442) (3).

Mutant used for description and seed stocks:

abo11.k (GSHO 233) in Trebi.
