Resumen:
Abstract Understanding the relationship between
domesticated crop species and their wild relatives is
paramount to germplasm maintenance and the utilization
of wild relatives in breeding programs. Recently,
Gossypium ekmanianum was resurrected as an independent
species based on morphological analysis of
specimens obtained from the Dominican Republic,
where the original type specimen was collected. The
molecular data presented here support the recognition
of G. ekmanianum Wittmack as a distinct species that is
phylogenetically close to G. hirsutum L. Analyses of
chloroplast DNA data reveal species-specific, indel
polymorphisms that unambiguously distinguish G.
ekmanianum samples from other polyploid congeners.
Furthermore, analysis of accessions that originated
from the Dominican Republic demonstrate the cryptic
inclusion of this sister taxon within the US National
Plant Germplasm System, a germplasm collection
maintained for diversity preservation and future breeding
resources. The data presented here indicate that
??wild?? G. hirsutum accessions may include the closely
related G. ekmanianum, and provide a method to easily
distinguish the two.
