BGS 5, Chlorina seedling 8, fch8
Stock number: BGS 5
Locus name: Chlorina seedling 8
Locus symbol: fch8
Previous nomenclature and gene symbolization:
Chlorina seedling 8 = f8 (4).
Chlorina seedling-f8 = clo-f8f8 (6).
Chlorina seedling-f8 = clo-f8f8 (6).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 7HS (2, 4, 5); fch8.j is about 13.0 cM distal from the nud1 (naked caryopsis 1) locus (2, 4); fch8.j is about 2.7 cM distal from the msg10 (male sterile genetic 10) locus (2); fch8.j is associated with SNP markers 1_1014 to 2_0445 (positions 80.65 to 121.90 cM) in 7H bins 06 to 07 of the Bowman backcrossed-derived line BW105 (1), likely in 7H bin 06.

Description:
Seedlings have a yellow-green color and plants retain a chlorina (yellow green) phenotype until ripening (2). Plants of Bowman backcross-derived line BW105 were viable in the field, but heading was delayed 2 to 10 days across environments. Plant height of BW105 varied from slight taller than Bowman to 3/3 of Bowman height and awns were slightly shorter. Spikes of BW105 had 2 to 3 more kernels than those of Bowman, seed weights were approximately 10% lower. Grain yields were 1/2 to 3/4 of those of Bowman (3).
