| dcterms.abstract | Sweet corn breeding goals differ from grain or silage corn. Sweet corn goals focus on marketable yield including several quality traits. This study explores the effect of a single cycle of full-sib selection and S2 selection on improving the marketable yield of an open-pollinated sweet corn population. The selected populations were subsequently compared in four environments for several plant-, yield- and quality traits relative to the original population. Analysis of variance was used to detect selection progress and indirect effects of selection. Full-sib and S2-selection decreased total yield. Marketable yield was decreased more by S2-selection than by full-sib selection. Flowering time was changed by full-sib selection, but not by S2-selection. Full-sib selection improved ear quality by increasing ear length, the diameter of the ear and the number of kernel rows. S2-selection showed no effect or a negative effect on ear quality. The application of a single cycle of selection using either method seemed inadequate for increasing marketable yield. More cycles might be necessary to make significant improvements. | eng |
