BGS 220, Chlorina seedling 3, fch3

BGN  48:104
Stock number: BGS 220
Locus name: Chlorina seedling 3
Locus symbol: fch3

Previous nomenclature and gene symbolization:

Chlorina seedling 3 = f3 (4).


Monofactorial recessive (4, 5).
Located in chromosome 1HS (4, 5, 6, 7); fch3.d is near the tip of 1HS and associated with SNP markers 2_0479 to 3_0969 (at position 0.0 cM) in chromosome 1H bin 01 of the Bowman backcross-derived line BW359 (1), .


Seedlings have bright yellow leaves, which gradually change color to light green as the plant grows. Plants are vigorous, but remain chlorina or light green until maturity. Plants expressing the fch3.d gene can be distinguished readily from normal plants at all stages of growth (4, 5). Heading of plants in the Bowman backcross-derived line for fch3.d (BW359) was delayed by 5 to 8 days, plants were about 3/4 of normal height, seeds were 10 to 20% lighter, and seed yields were less than 1/2 of normal (2).

Origin of mutant:

A spontaneous mutant in an unknown six-rowed cultivar (4).

Mutational events:

fch3.d (GSHO 851, Minn 89-4) in an unknown cultivar (3).

Mutant used for description and seed stocks:

fch3.d (GSHO 851) in an unknown cultivar; fch3.d in Bowman (PI 483237, NGB 22812)*6 (GSHO 2033); fch3.d in Bowman*7 (BW359, NGB20598).
