BGS 17, Chlorina seedling 4, fch4

BGN  43:54
Stock number: BGS 17
Locus name: Chlorina seedling 4
Locus symbol: fch4

Previous nomenclature and gene symbolization:

Chlorina seedling 4 = f4 (5, 8).
Yellow viable = yv (8).


Monofactorial recessive (8).
Located in chromosome 7HL (2, 3, 7, 8); fch4.g is slightly distal from the nud1 (naked caryopsis 1) locus (3); fch4.g is about 4.4 cM proximal from the lks2 (short awn 2) locus (3); fch4.g is associated with SNP marker 2_0042 (position 118.80 cM) in 7H bin 07 of the Bowman backcross-derived line BW360 (1); fch4.g is associated with SNP markers 1_0050 to 2_0042 (positions 87.33 to 118.80 cM) in 7H bins 06 to 07 of the Bowman backcross-derived line BW337 (1), in 7H bin 07.


Seedlings are bright yellow-green on emergence and maintain this color until they are nearly mature. Seedlings and plants are relatively vigorous, but heading is delayed (8). Bowman backcross-derived plants with fch4.g gene, BW360, showed a 7 to 11 day delay in heading and are about 10% taller than Bowman. Spikes have one or two more kernels, kernels are slightly thinner and kernel weights were reduced by 10 to 20%, test weights were slightly lower, and grain yields were about half that of Bowman (4).

Origin of mutant:

A beta-ray induced mutant in Montcalm (CIho 7149) (8).

Mutational events:

fch4.g (Alb Acc 258, GSHO 1214) in Montcalm (CIho 7149) (8).

Mutant used for description and seed stocks:

fch4.g (GSHO 1214) in Montcalm; fch4.g in Bowman (PI 483237)*7 (GSHO 1851, BW360, NGB 20599); fch4.g in Bowman (PI 483237)*7 (BW337, NGB 22132).
