BGS 365, Male sterile genetic 9, msg9
Stock number: BGS 365
Locus name: Male sterile genetic 9
Locus symbol: msg9
Previous nomenclature and gene symbolization:
Male sterile 9 = ms9 (4).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 2HS (2, 4); msg9ci is about 6 cM from the T2-7a translocation point (4); msg9.ci is over 18.7 cM distal from the eog1 (elongated outer glume 1) locus (2); msg9.ci is associated with adjacent SNP markers 1_0786 to 2_1242 (position 133.59 cM) in 2H bin 09 in a plant from Bowman backcross-derived line BW592 (1). The position of the msg9 locus based on SNP data does not correspond to the linkage based map distances.
Description:
Selfing - 10% at Bozeman, Montana and 24% at Tucson, Arizona, USA (3).
Outcrossing - complete female fertility (3).
Stamens - anthers smaller than fertile sib (4), stomium present and filament elongation occurs (5).
Pollen - stained in plants grown in the field and in the greenhouse, in some samples the grains appear normal (5).

Mutational events:
msg9.ci (MSS057, GSHO 2408) in Vantage (CIho 7324) (4).
Mutant used for description and seed stocks:
msg9.ci (GSHO 2408) in Vantage; msg9.ci in Bowman (PI 483237)*7 (GSHO 1883, BW592, NGB 24138).
