The vrs1 (Hordeum) Gene
Gene Classes : Intermedium spike, Six-rowed spike, Awnless lateral floret
|
|
Vrs1 normal phenotype (dominant)
|
vrs1 mutant phenotype (recessive)
|
Description:
Alleles at this complex
locus modify development of the cultivars and produces well-developed lateral
spikelets. The lemma awn of lateral spikelets will vary from 3/4 to nearly
as long as those of central spikelets, depending upon alleles present at
other loci. The Vrs1.b allele (V gene, distichon) is present in many two-rowed
cultivars and reduces lateral spikelets to sterile bracts with a rounded
tip.
