| Abstract: | The karyotype of(garden pansy)Viola tricolor var.hortensis was analyzed.The chromosome numbers of the somatic cell are 2n=2x=26.The karyotype formula is 2n=26=14m(4SAT) 6sm 2st 4T.The result of chromosome examination showed that it belongs "2C" type of Stebbins' karyotype asymmetry.That means it is a primitive species. |
