New Single Cross Glutinous Cam Hybrid Cultivars: Value Enhancement by Adding Sweet Taste from Super Sweet Corn
Glutinous or waxy corn (Zea mays L. var. ceratina) is commercially grown for green corn in several Asian countries including Thailand, some parts of China, Japan and Korea. It has taste similar to sticky rice because its endosperm contains similar starch, amylopectin. Most glutinous corns presently grown in Asian countries are open-pollinated cultivars. These local cultivars show high variation in ear size, ear shape, kernel color and eating quality. A glutinous corn hybrid breeding program has been carried out since 2001 at the Plant Breeding Research Center for Sustainable Agriculture, Faculty of Agriculture, Khon Kaen University, northeast Thailand to develop new cultivars with better eating quality and ear appearance, such as sweet taste, kernel color and size. Glutinous corn cultivars from Thailand and China, and super sweet corn cultivars from Thailand and USA were used to develop two base populations, with white and yellow kernels, respectively. Inbred lines were extracted and tested to produce single cross hybrids. As a result, three single cross glutinous hybrids, one white and two bi-color (white and yellow kernels) have been developed. These hybrids are the first of an entirely new type of glutinous corn that has 75％ waxy kernels and 25％ super sweet kernels, which provide an extra kick of sweetness and result in delightful eating quality. These cultivars produce well filled ears with 12～16 rows and can be harvested about 60～75 days after planting. Husked ears average 16cm in length, 4.3cm in diameter, and 180～200g ear weight. The hybrids are now being tested for commercial production in Asian countries.
