BGS 55, Chlorina seedling 1, fch1
Stock number: BGS 55
Locus name: Chlorina seedling 1
Locus symbol: fch1
Previous nomenclature and gene symbolization:
Chlorina seedling = f (6).
Light green = lg (5).
Light green 8 = lg8 (4).
Light green 10 = lg10 (4).
Light green = lg (5).
Light green 8 = lg8 (4).
Light green 10 = lg10 (4).
Inheritance:
Monofactorial recessive (3, 5, 6).
Located in chromosome 2HS (3, 10); fch1.a is in the centromeric region and about 4.0 cM distal from the eog1 (elongated outer glume 1) locus (3, 7); fch1.a is associated with SNP markers 1_1493 to 2_0458 (positions 76.05 to 96.47 cM) in 2H bins 06 to 07 of the Bowman backcross-derived line BW351 (1),

Description:
Seedling and immature leaves are very pale yellow-green (chlorophyll deficient) (6). The leaves gradually change to a green color beginning with the leaf tip. Plants can be grown to maturity in the field, but they have a slightly yellow-green color and are stunted easily by stress. Plants of the Bowman backcross-derived line with fch1.p (BW351) headed about 10 days later than Bowman and were slightly shorter. Plants produced a few more kernels per spike and rachis internodes were slightly shorter. Kernels were 10 to 15% lighter and they were slightly shorter and thinner. Grain yields of BW351 were 1/2 to 2/3 of thoser of Bowman (2).

Origin of mutant:
A spontaneous mutant in Golden (Gull, NGB 1480, CIho 1145, GSHO 466) (6).
Mutational events:
fch1.a (GSHO 112) in Gull (NGB 1480, CIho 1145, GSHO 466) (6, 9); fch1.p (lg) (Minn 80, GSHO 548) (5, 9); fch1.q (lg8) (No 155, GSHO 8) (4, 8); and fch1.r (lg10) (No 157, GSHO 154) in Himalaya (CIho 1312) (4).
Mutant used for description and seed stocks:
