BGS 34, Male sterile genetic 50, msg50
Stock number: BGS 34
Locus name: Male sterile genetic 50
Locus symbol: msg50
Previous nomenclature and gene symbolization:
Male sterile genetic hm = msg,,hm (4).
Male sterile genetic gh = msg,,gh (4).
Monofactorial recessive (3, 4).
Located in chromosome 7HL (2); about 13.6 cM from the lks2 (short awn 2) locus (2); msg50.hm is associated with SNP markers 2_0230 to 2_1229 (positions 118.80 to 176.37 cM) in 7H bins 07 to 10 of the Bowman backcross-derived line BW588 (1); msg50.gh is associated with SNP markers 2_13350 to 2_03859 (positions 107.44 to 152.29 cM) in 7H bins 07 to 10 of the Bowman backcross-derived line BW 972 (1).
Selfing - 0% is reported (4), but occasionally 5 to 10% selfed seed set is observed.
Outcrossing - complete female fertility (4).
Stamens - anthers slightly smaller than fertile sib with filament elongation and stomium (4).
Origin of mutant:
A spontaneous mutant in Maris Mink (PI 467824) (4).
msg50.gh in Maris Mink (MSS435) (2, 4); msg50.hm (MSS466, GSHO 2404) in Berac (PI 355136) (2, 4).
Mutant used for description and seed stocks:
msg50.hm in Berac (GSHO 2404); msg50.hm in Bowman (PI 483237)*7 (GSHO 1861, BW588, NGB 23448); msg50.gh in Maris Mink (MSS435), msg50.gh in Bowman*4 (BW972, NGB 23467).
