ObjectiveThe present experiment was conducted to enrich the table grape varieties and extend the supply period of table grapes, in order to effectively promote the sustainable and healthy development of table grape industry in Guangxi. Method‘Shine Muscat’ grape was introduced and cultivated in Nanning, Guangxi. The botanical characteris-tics , phenology , growth habit , fruit character and disease resistance of ‘Shine Muscat ’ grape were observed , and the double-harvest-a-year cultivation technology was studied. ResultAfter four years’ introduction and observation, it was found that ‘Shine Muscat’ grape could successfully achieve a double-harvest-a-year cultivation in Guangxi.
