BGS359

Stock number: BGS359
Locus name: Male sterile genetic 3
Locus symbol: msg3

Previous nomenclature and gene symbolization:

Male sterile 10 = ms10 (1, 5).

Male sterile 3 = ms3 (1, 3).
Inheritance:

Monofactorial recessive (3).

Located in chromosome 2S (3), about 4.6 cM distal from the e (elongated

outer glume) locus and 0.6 cM distal from the f1 (chlorina

seedling 1) locus (3).
Description:

Selfing - none (1, 3).

Outcrossing - complete female fertility (1, 3).

Stamens - anthers much smaller than fertile sib (1), no stomium or filament

elongation (4).

Pollen - non-staining, no free pollen grains (4).

The male sterile plants are also about 1/3 normal size with short, wide leaves

(1, 3). 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 (3).
Origin of mutant:

An acetone induced mutant in Gateway (CI 10072) (3).
Mutational events:

msg3.cc (MSS51) in Gateway (2, 3).
Mutant used for description and seed stocks:

msg3.cc in Gateway (T26-1); msg3.cc in Bowman*7 (BGS5120).
