Consumers currently prefer healthy food with antioxidant or anti-diabetic activities. This study was conducted to develop a waxy corn with high carotenoid content. A yellow waxy corn single cross hybrid 'Goldchal' was developed by Gangwon Agricultural Research and Extension Services in 2015. The seed parent inbred HW16 was crossed with the pollen parent inbred HW17 in 2010. The number and weight of fresh ears per 10 a for 'Goldchal' were 6,385 and 1,339 kg, respectively, comparable to those of 'Ilmichal' in regional yield trials from 2013 to 2015. The hybrid contained 15.8 mg/kg carotenoids, which were 15.0 mg/kg higher than that of 'Ilmichal'. The lodging tolerance of 'Goldchal' was superior to that of 'Ilmichal' and resistance to disease and insects was similar to those of 'Ilmichal'. The silking date of the seed parent HW16 was in the pollen dispersal period of the pollen parent HW17, and F1 seed yield was 186 kg/10a. 'Goldchal' could be cultivated throughout Korea. The plant variety protection right of 'Goldchal' was registered in June 2017 (Grant Number 6722).
