Physicochemical Properties and Wet-Milling Qualities of Dent Corn (Zea mays indentata L.) Hybrids Grown in Tokat and Samsun Locations of Turkey

The aim of this research was to investigate physicochemical properties and wet-milling qualities of commonly grown dent corn (Zea mays indentata L.) hybrids (Isıdora, Helen, Shemal, Tietar and P32W86) grown in Tokat and Samsun locations of Turkey. Grain yields were much higher in Tokat (average 1577 kg da-1) than in Samsun (average 1232 kg da-1). Corn hybrids varied significantly by genotype in such physical properties as thousand-kernel weight, hectoliter weight, hardness and density, and mean values were respectively 372.8-379.3 g, 77.6-77.7 kg, 18.8-19.7 sec and 1.30-1.29 g cm-3. Chemical compositions of corns differed by hybrid and to some extent by growing location and year. All hybrids, especially Helen, Shemal and P32W86, exhibited wet-milling results (yields: starch 64.2-64.6%, gluten 13.0-14.1%, fiber 10.1-10.5%, germ 6.8-7.1% and steep-water solids 4.7-4.9%) that were comparable to industrial wet-processing. Significant correlations were determined among physical, chemical and wet-milling properties of corn hybrids. Considering higher grain yields but similar wet-milling qualities, Tokat appears to be better suited than Samsun for starch-oriented dent corn production.
