Resumen:
A new form of great headed garlic (GHG), was collected, grown and
utilized as garlic in the province of Mendoza, Argentina. It was found
in contrast to other known forms of GHG that this novel form is
fertile, while other characteristics remained unknown. Studies revealed
that all accessions investigated formed large bulbs and produced fertile
seeds, with a germination rate of around 30%. Genome size analysis
and chromosome counting of the GHG accessions, made in comparison
with hexaploid forms of GHG, revealed that the accessions were
octoploid, with a genome size ranging from 119.5 to 122.4 pg.
Preliminary karyotype analysis indicates a possible allopolyploid
origin. It is suggested that this fertile accession deserves further
attention as a novel source of genetic variation in garlic-like-plants.
