Abstract

Somatic chromosome numbers of Actinidia deliciosa cvs. ‘Matua’ (staminate clone), ‘Abbott’ and ‘Bruno’ (pistillate clones) and two native wild species, A. polygama and A. arguta were studied using the squash and flame-drying methods. The chromosome counts of the commercial cultivars were 2n=174, whereas those of A. arguta were 2n=58, 116 and 174 and those of A. polygama were 58. These data confirm earlier findings that the basic chromosome number is x=29(11) and that with increasing polyploidy, the number of nucleoli increased correspondingly.
