'Mihwang', a Korean selection of loquat (Eriobotrya japonica), and its commercialization
In Korea, about 82 ha of loquat is cultivated in the south coastal area. However, most local cultivars are small and very sour, which makes consumers choose other fruits. 'Mihwang' is the first loquat to be selected in Korea, released by the fruit research institute of JARES in 2002. The tree vigor of 'Mihwang' is very strong, and the tree shape is widely open. 'Mihwang' is more resistant to low temperature in winter than 'Nagasakiwase', although loquat, as a subtropical tree, is still sensitive to low temperature compared with temperate-zone trees. So, the selection of warmer places for planting is very important, such as Jeju island and southern coastal area of Jeonnam and Gyeongnam provinces. Harvest season is mid-late June. The fruit surface color is orange, and the fruit is very juicy. Soluble solid content is around 13 °Brix. Average fruit weight is 30 g but can be 50-60 g fruit-1. The pure flesh rate without seeds is high (70%). Average yield is about 7-10 t ha-1. At present, 'Mihwang' is cultivated on 30 ha.
