BGS 645, Bushy spike 1, bsp1
Stock number: BGS 645
Locus name: Bushy spike 1
Locus symbol: bsp1
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive, homozygotes do not produce anthers or ovaries (1).
Location is unknown.
Location is unknown.
Description:
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).
