The Raw1 (Hordeum) Gene
Gene Class : Smooth Awn
|
|
Raw1 rough awn phenotype
(dominant)
|
raw1 smooth awn phenotype
(recessive)
|
Description:
Barbs or teeth on the margins of the
awn are absent and the size and
number of barbs on the central vein are reduced. Plants
homozygous
for the raw1.a allele have a semi-smooth awn when other recessive genes reducing
the number
and/or size of the barbs are absent. The presence of these other genes may
cause a
complete absence of barbs on the awn. The number
of stigma hairs is relatively small
in plants homozygous for raw1.a, and reduced seed set may occur in some
genotype-environment combinations.
