BGS 260, Chlorina seedling 11, fch11

BGN  45:120
Stock number: BGS 260
Locus name: Chlorina seedling 11
Locus symbol: fch11

Previous nomenclature and gene symbolization:

Pale green = pg (3).
Chlorina seedling 11 = f11 (1).


Monofactorial recessive (3).
Located in chromosome 6HL (5); fch11.t is about 6.1 cM distal from the rob1 (orange lemma 1) locus (3, 5); fch11.t is associated with SNP markers 2_0651 to 1_0377 (positions 89.78 to 91.91 cM) in 6H bin 07 in Bowman backcross-derived line BW353 (2).


Seedlings are pale yellow-green and often have white blotches on the seedling leaves. Plants remain light green until maturity (3). Compared to Bowman, plants of the Bowman backcross-derived line for fch11.t, BW353, headed 2 to 4 days later and were slightly taller. Kernels of BW353 were 10% lighter only in drought stressed environments. Grain yields of BW353 were 1/2 to 3/4 of those for Bowman (4).

Origin of mutant:

An X-ray induced mutant in Himalaya (CIho 1312) obtained by Caldecott and North at the University of Minnesota (1).

Mutational events:

fch11.t (GBC357 and GBC359, GSHO 1738) in Himalaya (CIho 1312) (1).

Mutant used for description and seed stocks:

fch11.t (GSHO 1738) in Himalaya; fch11.t in Bowman (PI 483237)*6 (GSHO 2082); fch11.t in Bowman*7 (BW353, NGB 20592).
