Open AccessDiversity in bread and durum wheat stigma morphology and linkage of increased stigma length to dwarfing gene Rht14
The dwarfing allele Rht14 of durum wheat associates with greater stigma length, an important trait for hybrid breeding, whilst major dwarfing alleles Rht-B1b and Rht-D1b showed little to no effect.
