BGN  45:190
Stock number: BGS 503
Locus name: Male sterile genetic 40
Locus symbol: msg40

Previous nomenclature and gene symbolization:

Male sterile ac = msg,,ac (5, 7).
Male sterile = ms-C (7).


Monofactorial recessive (5).
Located in chromosome 6HL (1, 2); is over 27.8 cM from the rob1 (orange lemma 1) locus (2); is associated with SNP markers 2_1025 to 2_0036 (positions 147.51 to 169.88 cM) in 6H bins 09 to 11 in a heterozygous plant from Bowman backcross-derived line BW577 (1).


Selfing - none (5).
Outcrossing - less than 30% in crosses and in the Bowman backcross-derived line (3, 5).
Stamens - anthers are smaller than those of fertile sibs, no stomium or filament elongation (5).
