BGS 191, Chlorina seedling 17, fch17

BGN  48:100
Stock number: BGS 191
Locus name: Chlorina seedling 17
Locus symbol: fch17

Previous nomenclature and gene symbolization:

Very yellow 3 = vy3 (3).
Chlorina seedling vy = fch.vy (3).


Monofactorial recessive (2).
Located in chromosomes 1HL or 3HL (1); fch17.vy is associated with SNP markers 1_0830 to 2_0138 (positions 130.68 to 202.26 cM) in 1H bins 11 to 14 and SNP markers 2_0130 to 1_0343 (positions 151.97 to 255.13 cM) in 3H bins 09 to 16 of the Bowman backcross-derived line BW344 (1).


Seedlings are pale yellow with a slight mottled type streaking and vigor is poor. The second leaf blade is chlorina with the tip gradually turning. Mature plants are normal green and have apparently normal vigor (3). In the Bowman backcross-derived line for fch17.vy (BW344), heading date was delayed by about 9 days compared to Bowman and grain yields were 50 to 70% of normal. Other morphological traits of BW344 plants were similar to those of Bowman (2). A new gene symbol is assigned to the vy3 mutant because no other chlorina mutant with a similar phenotype, except fch7, is associated with either 1HL or 3HL (1, 2).

Origin of mutant:

A spontaneous mutant in Himalaya x Ingrescens (GSHO 681) probably isolated by Tak Tsuchiya (3).

Mutational events:

fch17.vy (E 37-517, NSL 30243, GSHO 1079) in Himalaya x Ingrescens (GSHO 681) (2, 3).

Mutant used for description and seed stocks:

fch17.vy (GSHO 1079) from Himalaya x Ingrescens; fch17.vy in Bowman (PI 483237, NGB 22512)*5 (BW344, NGB 22139).
