Experiment on Introduction of Actinidia chinensis‘Donghong’

In 2014, scions were collected from 1-year branch of 9-year Actinidia chinensis ‘Donghong’ in Wuhan, Hubei province. In 2015, they were grafted on 8-year A. deliciosa ‘Bruno’ in Taishun and on 1-year A. chinensis in Jiangshan, Shangyu. From 2016, fruit yield was measured every year, and from 2018, phenophase was observed. During 2020 and 2021, determination was implemented on tree growth, fruit bearing habit, fruit morphology, fruit quality and storage time. The result showed that 'Donghong' had strong growth potential with 90% shoot ability, fruit yield with 10 500 kg/ha （top grafting） and 5 250 kg/ha （1-year rootstock） 1 year after grafting. The fruit yield was topped to 30 000 kg/ha in the 5^th and 6^th year after grafting, with SSC 15.6%-16.9% and DM 17.8%-18.6% , high resistance to soft rot and good storability. Under （1.5±0.5） ℃, fruit could be stored for 20 weeks.
