Plentiful awn variations have been discovered in hexaploid wheats, while less were observed in diploid and tetraploid wheats. However, a double ditelosomic line of 6B (dDT6B) in tetraploid wheat cultivar DR147 specifically displayed awnless phenotype, which arised from the presence of awning inhibitor B2 located in telosome 6BL derived from hexaploid wheat cultivar Chinese Spring (CS). B2 locus was definitely proved to be essential for the awnless phenotype and the partial dominance effect of… CONTINUE READING
