Green King', a new green tetraploid table grape cultivar with large berries, was originated from a cross between ‘Tensyu’ and ‘Beni Fuji’ grape cultivar in 2000. The cultivar was preliminarily selected among the elite breeding lines for its superior growth characteristics in 2005. After an extensive three-year evaluation of fruit and tree characteristics as 'GWG2002-02', 'Green King' was finally selected in 2008. Under Chuncheon’s ecological conditions, the average harvest date for 'Green King' is 6 September, and the number of days from flowering to harvest is 88 days. Hence, it is 12 days shorter than 'Rosario Bianco'. The average weight of a cluster in 'Green King' is 379.6 g, and its yield is 1,852 kg/10a. It has larger fruit size and higher fruit productivity than ‘Rosario Bianco’ (Registration No. 3560).
