Authors: K. Phivnil, K. Beppu, T. Takamura, T. Fukuda and I. Kataoka
Abstract:
Ploidy of accessions of Actinidia arguta and A. rufa in the collections conserved at Kagawa Prefectural Agricultural
Experiment Station and Kagawa University was assessed by flow cytometric analysis.
In A. arguta, intraspecific
variation of ploidy in the ranges of 2x, 4x, 6x and 7x was observed.
One wild type; 'Gassan' and locally selected
cultivar; 'Mitsuko' were hexaploid.
Ploidy of two accessions of Issai varied between 6x and 7x.
All of the 11
accessions of A. rufa were diploid.
Introduced accessions of A. chinensis contained diploid and tctraploid forms,
whereas all the cultivars of A. deliciosa were hexaploid.
