  • 'Heukisul' (3x) a cross made in 2000 between 'Kyoho' (4x, Vitis sp.) and 'Thompson Seedless' (2x, Vitis vinifera L.) in a seedless grape breeding program, was preliminarily selected in 2004. After regional adaptation testing under the name of 'KTS014' at two sites during 2004-2005, it was finally selected in 2006. 'Heukisul' showed low incidence of berry shattering, resulting in a good berry set compared to 'King Dela'. 'Heukisul' had budburst on April 23, flowering on in June 9, and fruit maturation in September 29 (almost the same as 'King Dela' at Chuncheon), and it was considered a midseason cultivar. The mean berry weight was 4.0 g, about 0.7 g heavier than 'King Dela', and mean soluble solids were $21.9\;^{\circ}Brix$, about $2.7\;^{\circ}Brix$ higher than 'King Dela'. The skin color was dark violet with abundant bloom and the flesh was very firm. Although the cluster was compact, it required no cluster thinning. Also the incidence of berry cracking was very low.
