Chromosome constitution of species in the plant genus Chaenomeles
Kauppinen, S.; Antonius-Klemola, K.; Tigerstedt, P.M.A.
The chromosome number was studied in plants, derived from seeds collected in the wild, of all four species (C. cathayensis, C. japonica, C. speciosa and C. thibetica) presently recognised in the genus Chaenomeles Lindl. (Maloideae, Rosaceae). For the first time the chromosome number of C. thibetica was also determined. Chaenomeles thibetica was diploid and had a chromosome number of 2n = 34. The results of chromosome counting in the three other species were in agreement with the literature. Thus, all species within the genus Chaenomeles were confirmed to be diploid and to have the same chromosome number, 2n = 34.
