This study was concerned with wheat grain protein in segregating and non-segregating populations. An attempt was made to develop a sampling technique which would reduce the magnitude of environmentally induced variation. Also, the genetic relationship between protein content and other plant and seed characters were investigated.
Wichita, a hard red winter wheat variety, and Atlas 66, a spring intermediate soft red wheat variety, were used as parents for the material involved in this study. Wichita served as the low-protein parent with Atlas 66 and high-protein parent. Variability of grain protein within plants and among plants was studied in the parents and the F1 of a cross of these two varieties. Grain protein content and six other plant and seed characters were studied in the parents, the F1, F2, and the backcrosses of the F1 to each parent. The six characteristics were flowering date, average head weight, grain yield, plant height, number of tillers, and awn type.
