Stock number: BGS 645
Locus name: Bushy spike 1
Locus symbol: bsp1

Monofactorial recessive, homozygotes do not produce anthers or ovaries (1).
Location is unknown.
The mutant plants appear normal except they form very bushy spikes caused by many awn-like structures. Spikelets of bsp1.a mutants lack reproductive tissue and are completely sterile. The mutant must be maintained as a heterozygote (1).
Origin of mutant:
A fast neutron induced mutant in Morex (CIho 15773).
bsp1.a (FN346, GSHO 3652) in Morex (CIho 15773) (1).
Mutant used for description and seed stocks:
