This study sought to evaluate fruit and seed characteristics after pollination by four pollen donors, denoted here as ‘SKK2’, ‘Deliwoong’, ‘Pohwa’, and ‘Chieftain’, and to select the best pollen donors for producing commercial fruits from the domestic kiwifruit (Actinidia chinensis) cultivars ‘Haeguem’ and ‘Redvita’. The fruit setting rates of ‘Haeguem’ and ‘Redvita’, which were pollinated by four pollen donors, exceeded 90% for two years. In the ‘Haeguem’ and ‘Redvita’ cases, the weight of the fruits was heaviest with ‘Chieftain’ and lightest with ‘Pohwa’. Regarding the fruit characteristics of ‘Haeguem’, the dry matter content and soluble solids content were highest for ‘Pohwa’ in 2019, and the malic and quinic acid contents were highest for two years with ‘SKK2’, whereas the other traits were not significant. The total number of seeds was highest with ‘Chieftain’ and lowest with ‘SKK2’ for two years. In ‘Redvita’, the dry matter content was high with ‘SKK2’ and ‘Deliwoong’ in 2019 and the level of titratable acidity was lowest for two years with ‘SKK2’, whereas the soluble solids content, organic acid content, and flesh color did not show significant results. The total number of seeds and the number of mature seeds in ‘Redvita’ were highest with ‘SKK2’, but the number of immature seeds was highest with ‘Chieftain’.
