BGS 468, Male sterile genetic 31, msg31

BGN  45:178
Stock number: BGS 468
Locus name: Male sterile genetic 31
Locus symbol: msg31

Previous nomenclature and gene symbolization:

Male sterile d = msg,,d (4).
Male sterile dwarf = msdwf (4).


Monofactorial recessive (3).
Located in chromosome 1HL (1); msg31.d is distal from the sls1 (small lateral spikelet 1) locus (3); msg31.d is associated with SNP markers 1_0434 to 2_0267 (positions 127.71 to 149.80 cM) in 1HL bin 11 and with SNP markers 1_1098 to 2_1274 (positions 161.08 to 218.47 cM) in 2HL bins 11 to 13 of a heterozygous plant from the Bowman backcross-derived line BW567 (1).


Selfing - none (6).
Outcrossing - complete female fertility (6).
Stamens - anthers rudimentary, no stomium or filament elongation (5).
In addition to male sterility, mutant plants are weak and short (about 1/2 normal height), show delayed development, and appear to lack surface wax on the spike (wax code - ++ ++) (2, 4).
