Genetics of Mutations Affecting the Development of a Barley Floral Bract [PDF]
Genetics, 2000 Abstract Two groups of mutants that affect the morphology of the lemma, a floral bract of barley, are described. The first comprises phenotypes associated with mutant alleles of calcaroides loci. On the lemma of these mutants, a well-organized neomorphic structure is formed, termed the sac.
