Study on Waxy Corn X. Analysis on Botanical Characteristics, Physicochemical Properties Related to Table Qualities of the Developed Waxy Corn Hybrids

This study was carried out to compare botanical characteristics, physicochemical properties related to table quality and feed values and develop a new variety among 12 developed waxy corn hybrids. These materials were produced in 2008 and cultivated in 2009 at Corn Breeding and Genetics Farm of Coll. of Agri. & Life Sci., Chungnam Nat l Univ. Botanical characteristics of used waxy corn hybrids showed large difference among hybrids; stem height,ear height and ear length. In physical properties, range of kernel sugar content among used hybrids appeared 16.1 to 13.0brix(%). CNU08H-15, CNU08H-35 and CNU08H-h39 among these were highly appeared as 15 above and pericarp thickness of Yeonongchal was very thick as 46.0 ㎛, while CNU08H-39 among hybrids showed the thinnest as 23.0 ㎛compared to other hybrids. Protein content as a indicator of table quality was the highest in Ilmichal among hybrids,while that of CNU08H-39 was the lowest, while amylopectin content was the highest as 94.5%, From experimental results, Daehakchal Gold 1, CNU08H-h121 and CNU08H-39including check Yeonyoungchal were highly evaluated as new hybrid in thinner pericarp, high amylopectin and chewiness.
