Stock number: BGS 505
Locus name: Male sterile genetic 42
Locus symbol: msg42

Previous nomenclature and gene symbolization:

Male sterile db = msg,,db (3).
Male sterile = B68-N-109 (3).

Inheritance:

Monofactorial recessive (3).
Located in chromosome 3H (2); msg42.db is over 18.9 cM from the alm1 (albino lemma 1) locus (2). msg42.db is associated with SNP markers 1_0672 to 1_1191 (positions 58.56 to 98.41 cM) in 3H bins 04 to 06 in a heterozygous plant from Bowman backcross-derived line BW579 (1).

Description:

Selfing - none (3, 4).
Outcrossing - complete female fertility (3, 4).
Stamens - anthers rudimentary, no stomium or filament elongation (3, 4).
