Karyotypes of three species of fragaria (rosaceae)

Abstract

Chromosome counts for three species and two varieties of Japanese Fragaria were determined. This is the first report of the chromosomes of F. nipponica var. yakusimensis. Fragaria nipponica var. nipponica, F. nipponica var. yakusimensis, F. nipponica var. yezoensis and F. vesca were very similar in karyotype morphology, but F. iinumae showed differences from those taxa. © 1989, Japan Mendel Society, International Society of Cytology.
