BGS 52, Chlorina seedling 15, fch15
Stock number: BGS 52
Locus name: Chlorina seedling 15
Locus symbol: fch15
Previous nomenclature and gene symbolization:
Orange seedling = or (3).
Inheritance:
Monofactorial recessive (3).
Located in chromosome 2HS (3); fch15.x is about 18.5 cM distal from the fch1 (chlorina seedling 1) locus (2, 3); fch15.x is associated with SNP markers 2_1338 to 2_0699 (positions 74.97 to 126.33 cM) in 2H bins 06 to 09 of the Bowman backcross-derived line BW357 (1), likely in 2H bin 06.

Description:
The normal color of seedlings is altered to "apricot yellow" when fch15.x plants are grown in the field under low temperature. Plants respond better to higher temperatures and can be grown to maturity in suitable environments (3, 4). The yellow color of fch15.x plants is stable nearly to maturity (4).
)
Origin of mutant:
A spontaneous mutant in Trebi (PI 537442) (3).
Mutational events:
fch15.x (or1.a) (Trebi IV, GSHO 49) in Trebi (PI 537442) (3).
Mutant used for description and seed stocks:
fch15.x (GSHO 49) in Trebi, fch15.x in Bowman (PI 483237, NGB 22812)*2 (BW357, NGB20596).
