BGN  48:172 Export to PDF
Stock number: BGS 661
Locus name: Double seed 1
Locus symbol: dub1

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (2).
Located in chromosome 5HL (2); dub1.1 is near AFLP marker E4038-4 in subgroups 66 to 67 of the Proctor/Nudinka map of chromosome 5H (2), dub1.1 is slightly distal from the mnd6 (many noded dwarf 6) locus (2), which is in 5H bin 10. (2).

Description:

The modification of the top of spike is distinctive and occurs on all tillers. The tip of the spike is compacted and a few spikelets form two and three fertile florets adjacent to each other. The double spikelets have fused lemmas and paleas often enclose the part of two, and occasionally more, florets: six anthers and two ovaries (1). The tip of the spike appears phenotypically similar to those of int-m (intermedium spike-m) mutants (1).

Origin of mutant:

An X-ray and ferrisulfate induced mutant in Bonus (NGB 14657, PI 189763) (1).
