Abstract
The present investigation on the chromosomes of Duchesnea confirmed previous reports indicating that D. chrysantha f. chrysantha has 2n=14 chromosomes and D. indica has 2n=84 chromosomes. The chromosome number of D. chrysantha f. leucocephala, 2n=14, was also ascertained, together with the meiotic chromosome numbers. The two taxa of D. chrysantha had very similar complements consisting of 5 pairs of metacentrics, one pair of metacentric SAT-chromosomes and one pair of submetacentrics. Duchesnea indica had subtelocentric SAT-chromosomes and many subtelocentric chromosomes in addition to metacentric and submetacentric chromosomes. The genome of D. indica contains a genome set involving subtelocentric chromosomes, which were not detected in D. chrysantha. This finding seems to be of importance in considering the course of evolution in D. indica.
