BGS 324, Curly dwarf 1, cud1

BGN  26:272
Stock number: BGS 324
Locus name: Curly dwarf 1
Locus symbol: cud1

Previous nomenclature and gene symbolization:

Curly dwarf = cud (3).


Monofactorial recessive (3).
Located in chromosome 5HL (3); cud1.a is about 14.4 cM proximal from the fst1 (fragile stem 1) locus (1, 2).


Most leaves are short and more or less twisted, and they often have a longitudinal crease. Culms are short (1/2 normal), the spike is compact, awns are short (1/3 normal length), and kernels are small and round (3).

Origin of mutant:

An ethyl methanesulfonate induced mutant in Akashinriki (OUJ659, PI 467400) (3).

Mutational events:

cud1.a (OUM120, GSHO 1711) in Akashinriki (OUJ659, PI 467400) (2, 3).

Mutant used for description and seed stocks:

cud1.a (GSHO 1711) in Akashinriki; cud1.a in Bowman (PI 483237)*6 (GSHO 2094); cud1.a in Bowman*8 (BW198, NGB 22030),
