Determination of Some Agronomic Performance in Crosses Between Dent Corn and Sweet Corn Inbreds Lines

This research was carried out in the experimental fields of ege university, faculty of agriculture, department of field crops in 2016-2017 wheat growing season. the aims of this study were to investigate some agronomic traits of the f1 generations derived from sweet corn x dent corn crosses and to develop promised sweet corn hybrids with high yield and quality properties. the crosses between parents were done at in 2016, two sweet corn inbred lines (9 and 57) were used as female parents while one dent corn inbred line (66) was used as the male parent, f1 seeds of two hybrids (9 x 66 and 57 x 66) were sown with their parents on may, 2017 in randomized complete block design with three replicates. plant height, height of first ear, ear length, ear diameter, ear weight with husk, ear weight without husk, ear/husk index, grain number per ear, grain/ear index and fresh grain yield traits were measured. it was found that both sweet corn x dent corn hybrids had greater values than those of sweet corn parents in terms of measured agronomic traits. besides, the hybrid 9x66 showed higher heterosis than 57 x 66 hybrid for all measured traits in the research. it has been concluded that after evaluating the quality and sensory characterization this hybrid (9 x 66), it can be used as a commercial sweet corn cultivar.
