| Abstract: | The somatic chromosome numbers of eight Colocasia taxa and the karyotypes of five species in the genus from China are reported here.The results are as follows: C.heterochroma H.Li et Z.X.Wei,2n=2x=28=18m 10sm; C.gongii C.L.Long et H.Li,2n=2x=28=18m (4SAT) 10sm (4SAT); C.gaoligongensis H.Li et C.L.Long,2n=2x=28=24m 4sm; C.lihengiae C.L.Long et K.M.Liu,2n=2x=28=18m (1SAT) 6sm 4st; C.bicolor C.L.Long et L.M.Cao 2n=28; C.lihengiae C.L.Long et K.M.Liu var. nigra C.L.Long 2n=3x=42; C.gigantea (Blume) Hook f.,2n=2x=28=22m 4sm 2st; C.konishii Hayata 2n=28.Their somatic chromosome numbers are reported here for the first time except those of C.lihengiae,C.gongii,C.gigantea and C.konishii .The karyotypes of C.heterochroma,C.gongii,C.lihengiae and C.gaoligongensis are recorded here for the first time. |
