BGN  41:120
Stock number: BGS 231
Locus name: Curly 5
Locus symbol: cur5

Previous nomenclature and gene symbolization:

Curly 5 = cu5 (3).


Monofactorial recessive (2, 3).
Located in chromosome 2HS (1); cur5.h is associated with SNP markers 1_1078 to 2_0476 (positions 66.78 to 96.47 cM) in 2HL bins 05 to 07 of the Bowman backcross-derived line BW225 (1); cur5.h is associated with SNP markers 1_0498 to 2_0476 (positions 81.43 to 96.47 cM) in 2HL bin 07 of the Bowman backcross-derived line BW250, which also contains dusky 1 (dsk1.a) (1). Previously located in chromosome 1HS (4); based on linkage drag with the sls1 (small lateral spikelet 1) locus (4).


Leaves are short and partially coiled, and awns are slightly coiled. Plants are semidwarf (2/3 normal height), have relatively short spikes, and are relatively weak (2, 3). Plants of the Bowman backcross-derived line for cur5.h, BW225, headed 3 days later than Bowman and were about half as tall. Leaf blades of BW225 were short and narrow compared to those of Bowman. Spikes contain 5 fewer kernels, kernel were narrower (3.3 vs. 3.7 mm), and kernel weights were 10 to 15% lower. (3).

Origin of mutant:

A sodium azide induced mutant in Glenn (CIho 15769) (2).

Mutational events:

cur5.h (GSHO 1710) in Glenn (CIho 15769) (2, 3).

Mutant used for description and seed stocks:

cur5.h (GSHO 1710) in Glenn; cur5.h in Bowman (PI 483237)*8 (BW225, NGB 22052); cur5.h with dsk1.a in Bowman*7 (GSHO 2045, BW250, NGB 22075).
