BGS 358, Male sterile genetic 2, msg2

BGN  45:128
Stock number: BGS 358
Locus name: Male sterile genetic 2
Locus symbol: msg2

Previous nomenclature and gene symbolization:

Male sterile 2 = ms2 (1).
Male sterile 2 = ms2 (4).


Monofactorial recessive (1).
Located in chromosome 2HL (1, 11); msg2.cb is about 2.4 cM proximal from the eog1 (elongated outer glume 1) locus (7); msg2.cb is less than 1 cM from the T2-7a translocation breakpoint and about 3 cM from the eog1 locus (8); msg2.cb is associated with SNP markers 2_0674 to 2-0585 (positions 85.71 to 103.71 cM) in 2H bins 07 to 08 of a heterozygous plant from Bowman backcross-derived line BW554 (2).


Selfing - none (4).
Outcrossing - complete female fertility (4).
Stamens - anthers smaller than fertile sib, no stomium or filament elongation (10).
Pollen - non-staining, shrunken, and no normal grains (10).
