BGS 190, Thick filament 1 (male sterile genetic), tfm1

BGN  48:99 Export to PDF
Stock number: BGS 190
Locus name: Thick filament 1 (male sterile genetic)
Locus symbol: tfm1

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (2).
Located in chromosome 1HL (1); tfm1.a is associated with SNP markers 2_0603 to 2_0915 (positions 199.04 to 202.94 cM) in 1H bin 14 of a heterozygous plant from the Bowman backcross-derived line BW877 (1),

Description:

The filaments supporting the anthers are much thicker than normal, having a stalk-like appearance and a light green color. Since the filaments do not elongate, the mutant plants are largely male-sterile. Pollen fertility is apparently normal because mutant segregates will set a few seeds. Besides very poor seed, tfm1 plants in Bowman backcross-derived line BW877 appear normal (2).

Origin of mutant:

A spontaneous mutant in the Volla (PI 280423) induced mutant 7060 backcrossed twice to Bowman (PI 483237, NGB 22812) (2).

Mutational events:

tfm1.a from Volla 7060/2*Bowman (2).

Mutant used for description and seed stocks:

tfm1.a from Volla 7060/2*Bowman (PI483237, NGB 22812); tfm1.a in Bowman*7 (BW877, NGB 22311).
