The triploid seedless grape cultivar ‘Heukarong’ was developed in 2002 through artificial hybridization between ‘Black Olympia’ and ‘Campbell Early’ From 2003 to 2013, field trials were conducted under conventional cultivation practices in Chuncheon, Gangwon State, confirming that ‘Heukarong’ possesses strong resistance to both diseases and frost without the need for special protective measures, thereby demonstrating high tolerance to both environmental and biotic stresses. Based on these findings, an intensive three-year comparative evaluation of growth and fruit characteristics between ‘Heukarong’ and the triploid cultivar ‘Sweet Dream’ was conducted beginning in 2014. The results showed that ‘Heukarong’ consistently produced fruit with commercially valuable traits, leading to its final selection in late 2016 for varietal registration. Under standard cultivation, ‘Heukarong’ can produce high-quality fruits averaging 436 g in weight with a soluble solid content of 19.4 °Brix through a single application of gibberellin at full bloom, making it highly competitive in the market. Furthermore, ‘Heukarong’ exhibits strong resistance to frost damage and berry cracking, indicating excellent adaptability and stable productivity even under suboptimal growing conditions (Cultivar Registration No. 7766).
