Abstract

Rubus croceacanthus (2n=14), R. minusculus (2n=14), and their F₁ hybrids were cytologically studied. Rubus croceacanthus and R. minusculus showed gradient and symmetric karyotypes uniformly formulated as 2n=14=10m+2sm +2'st. Their F₁ hybrids also had the same karyotypic formulae as the parental species. Almost all PMCs of F₁ hybrids showed seven bivalents, and univalents were rare. The karyotypic uniformity between the two species, and the preponderant formation of seven bivalents in their F₁ hybrids indicates that R. croceacanthus and R. minusculus are closely related species with no perceptible difference in their genomes.
