BGS 359, Male sterile genetic 3, msg3
Stock number: BGS 359
Locus name: Male sterile genetic 3
Locus symbol: msg3
Previous nomenclature and gene symbolization:
Male sterile 10 = ms10 (3, 8).
Male sterile 3 = ms3 (3, 5).
Male sterile 3 = ms3 (3, 5).
Inheritance:
Monofactorial recessive (5).
Located in chromosome 2HS (5); msg3.cc is about 4.6 cM distal from the eog1 (elongated outer glume 1) locus (5); msg3.cc is 0.6 cM distal from the fch1 (chlorina seedling 1) locus (5); msg3.cc is associated with SNP markers 1_1493 to 1_1046 (positions 76.05 to 96.47 cM) in 2H bins 06 to 07 of a heterozygous plant from the Bowman backcross-derived line BW565 and with small regions of 1H and 3H (1, 2).

Description:
Selfing - none (3, 5).
Outcrossing - complete female fertility (3, 5).
Stamens - anthers much smaller than fertile sib (3), no stomium or filament elongation (6).
Pollen - non-staining, no free pollen grains (7).
The male sterile plants are also about 1/3 normal size with short, wide leaves (3, 5). Spikes are dense and spikelets are small and malformed, awns are 1/3 normal length, and double or triple pistils (fasciation) occur in some spikelets (5). The fused double and triple kernels, which developed after pollination of male sterile plants, were likely caused by failure of rachilla abortion and partial fusion of adjacent florets (2). Partial fertility was observed in mutant plants of the BW565 stock when they were grown in 2013 and 2014 at Lund, Sweden (6).
