        Super-sweet corn controlled by shrunken2 (sh2) was first introduced into Korea three decade ago, but its cultivation and uses have not been popularized. Main reasons of the un-popularity are considered as lack of locally bred adapted cultivars, low germination, too sweet and less chewing of the green ears. Considering traditional and favorable eating habits of glutinous waxy corn by Koreans, we initiated to develop a double mutant wx/sh corn that has 3:1 segregation in an ear from 1996. First we formed several double cross hybrids using commercial single crosses of wx and sh2 hybrid considering seed production difficulties. The results showed that a double mutant corn hybrid showed high germination, and high palatability score with tolerance to major diseases and insects in Korea. In 2008, we conducted single and double cross trials in Gokseong, South Jeolla-do. The yield of waxy-super sweet was higher than both waxy and super sweet corn with good agronomic traits of ear height, ear weight, ear length and plant height. Among waxy-super sweet corn single cross was even better than double cross in all parameters. This double mutant approach shall be an outstanding option to change of traditional food habits into a new eating pattern. This attempt has potential success of commercial wx/sh hybrid corn development.
