Abstract:

This research was conducted to determine certain quality traits of new sweet corn varieties of sugary (su), sugar-enhanced (se) and shrunken (sh2) types in Tokat/Kazova conditions. A composite variety together with thirteen F1 sweet corn varieties with various sugar contents and grain colors were included in the research. The field trials were conducted in 2009 and 2010 growing seasons by the randomized complete block design with three replications, and water-soluble solids (WSS), sucrose contents, moisture contents and color traits (L*, hue and chromo) were investigated. Significant differences were obtained in the investigated characteristics, except for WSS contents by year and moisture contents by genotype. WSS contents of genotypes varied from 10.7 to 21.2 in °Brix. Average WSS contents as °Brix were 17.8 in the varieties of su-types, 18.9 in the se-types and 12.4 in the sh2-types varieties. Sucrose contents of the genotypes, on a dry-matter basis, ranged from 14.6 to 40.9%, while mean sucrose contents of su-, se- and sh2-types were 17.0%, 30.4% and 35.0%, respectively. Mean moisture contents of the varieties at harvest were quite similar (75.4-75.9%). It is important that the genotypes with better performance in grain yield and quality by locations be cultivated accordingly.
