BGS 500, Male sterile genetic 37, msg37
Stock number: BGS 500
Locus name: Male sterile genetic 37
Locus symbol: msg37
Previous nomenclature and gene symbolization:
Male sterile hl = msg,,hl (4).
Inheritance:
Monofactorial recessive (4, 5).
Located in chromosome 3HL most likely (1), msg37.jx is associated with SNP markers 3_1220 (position 182.97 cM) in 3H bin 12 in the homozygous partially sterile Bowman backcross-derived line BW573; msg37.hl is associated with SNP markers 2_0797 to 1_1516 (positions 5.45 to 249.75 cM) in 3H bins 01 to 16, plus SNP markers in all other chromosomes, in a heterozygous plant from Bowman backcross-derived line BW970 (1).
Description:
Selfing - none to 6% or more (4), the degree of selfing seems sensitive to environmental conditions, favored by cool conditions (3).
Outcrossing - complete female fertility (4).
Stamens - anthers shrunken, no stomium or filament elongation (3) to nearly normal (4).
The level of self-fertility in msg37.hl and msg37.jx plants gradually increased as more backcrosses to Bowman were made. The level of self-fertility approached 80% in BW573, a selection with the msg37.jx allele from the sixth backcross to Bowman (3).

Origin of mutant:
A spontaneous mutant in Clermont (PI 343724) (4).
Mutational events:
msg37.hl (MSS465, GSHO 2389) in Clermont (PI 343724) (2, 4); msg37.jx (MSS529, GSHO 2389) in a dwarf mutant 17:17:2 (sdw.ax, DWS1009, GSHO 2437) selected from Birgitta (NGB 14667, NGB 1494, NSGC 1870) (2, 4).
Mutant used for description and seed stocks:
msg37.hl (GSHO 2389) in Clermont; msg37.hl in Bowman (PI 483237)*5 (BW970, NGB 24149); msg37.jx (GSHO 2437) from Birgitta; msg37.jx in Bowman (PI 483237)*7 (GSHO 2303, BW573). (The BW573 seed stock is maintained as homozygous for the msg37.jx allele).
