摘要：Nuclear phenotype and chromosome characteristics of eight types of Impatiens balsamina L. were studied. The diploid chromosome number was found to be 2n=14 in all types of Impatiens balsamina . Interphase chromosome volume was found to range from 0.1665Î¼3 (violet type) to 0.3904 Î¼3 (red type). The maximum total chromatin length (24.73Î¼m) was observed in pink type and minimum (11.70Î¼m) in violet type. Maximum total frequency percent (50.00%) was found in both foreign types (red and violet) and minimum (48.03%) in violet type. The karyotype analysis revealed that there was no secondary constriction and sub-terminal chromosome in any of the seven types belonging to Impatiens balsamina . So, on the basis of karyotypic analysis the present findings indicated that all the types of Impatiens balsamina were of primitive nature.
