Abstract

Seedlings derived from an Actinidia interspecific cross between the hexaploid Actinidia chinensis var. deliciosa ‘Jinkui’ and the diploid male A. eriantha × A. chinensis var. chinensis ‘Chaohong’ hybrid were analyzed using flow cytometry, SSR markers and phenotypic observations. The results show that the leaf vitamin C content of this hybrid population has a mid-parent heterosis. Separation of flower color in the progeny was also observed, progeny with red flowers lighter than ‘Chaohong’, white flowers as in ‘Jinkui’ and intermediate types with a red base to the petals and white margins were all present. Flow cytometry analysis confirmed that most of the progeny were tetraploids, and molecular marker data showed that most of these tetraploid progeny had three alleles from the hexaploid parent and one allele from the diploid parent. UPGMA analysis based on the SSR markers showed that the diploid parent was completely separated from the hexaploid parent and all the progeny.
