Comparisons of Pericarp Thickness And Sugar Content on New Waxy Corn Hybrids

ABSTRACT For waxy corn hybrid development, 23 waxy corn hybrids were planted and surveyed in both pericarp thickness and sugar content. Pericarp thickness showed average 50 to 49 μm in field and greenhouse. Results like these advanced than previous other hybrids. Also, sugar content in developed waxy corn evaluated as 13.6 to 15.3 brix. Here, we concluded that edible quality of waxy corn depended on combing of two factors. Especially, CNU11H8 hybrid at field and CNU11H-38 at greenhouse were good in both factors. Accordingly, these hybrids will be planted in next time for productivity and area adaptation. Keywords : pericarp thickness, sugar content, waxy corn, hybrids Waxy corn, a single recessive gene ( wx ) was located on the short arm of chromosome 9, co des for the waxy endosperm of the kernel(Collins, 1909).These fresh waxy corn was a very popular food in Asian countries including Korea.Hong (1994) suggested that it is necessary to study on waxy corn hybrids in order to improve its quality and nutritional composition cultivated traditionally.
