The pro-metaphase and metaphase chromosomes stained
with DAPI produced the best results for chromosome observation
and counting in both octoploid and diploid species.
Counting of the chromosomes confirmed that both cultivars of
F.ananassa and F. vesca are, respectively, octoploid 2n = 56
and diploid 2n = 14. In addition, chromosome observations
based on methods used in this experiment are considered to
be useful not only for strawberry chromosome counting; they
are also fundamental to cytological, genetic, and molecular
cytology of strawberry plants.
