BGS 177, Chlorina seedling10, fch10

BGN  43:95
Stock number: BGS 177
Locus name: Chlorina seedling10
Locus symbol: fch10

Revised locus symbol:

The fch10.s is an allele at the zeb2 (zebra stripe 2) locus based on phenotypic expression and retained SNP markers in 4H of the Bowman backcross-derived lines BW 352 with fch10.s and BW931 line with zeb2.b (1). See BGS 461 for further information on the zeb2 locus.

Previous nomenclature and gene symbolization:



Monofactorial recessive (5, 6).
Located in chromosome 4H (3, 4, 5); fch10.s is about 9.3 cM distal from the Kap1 (Hooded lemma 1) locus (3, 4); fch10.s is about 17.0 cM proximal from the glf3 (glossy leaf 3) locus (3, 4); no recombination between fch10.s and the lgn4 (light green 4) locus (3, 4) has been observed; fch10.s is associated with SNP markers 1_0668 to 1_1224 (positions 63.19 to 91.93 cM) in 4H bins 05 and 06 of the Bowman backcross-derived line BW352 (1), in 4H bin 05 near the centromere.


Plants are nearly normal green on emergence at 20°C gradually fading to light green, which is maintained to adult stages. Viable, though somewhat weak under outdoor conditions, and develops chlorina leaves from seedling to near maturity (5). When compared to Bowman, the Bowman backcross-derived line for fch10.s (BW352) headed about 17 days later and produced little or no seed. Rachis internodes were slightly shorter and plants were 1/2 to 3/4 of normal height (2).

Origin of mutant:

A spontaneous mutant in an unknown cultivar isolated by R.W. Woodward (4, 5, 6).

Mutational events:

fch10.s (GSHO 1737, T. 95) in an unknown six-rowed cultivar (4, 5); based on SNP patterns the fch10.s mutant studied by Woodward originated in six-rowed barley Himalaya (1).

Mutant used for description and seed stocks:

fch10.s (GSHO 1737) in an unknown six-rowed cultivar; fch10.s in Bowman (PI 483237)*7 (BW352, NGB 20591).
