Ten hexaploid winter triticales were grown at three sites in western Switzerland for two cropping periods. The grains were analyzed for their concentration of N. Averaged across the environments, entries 50728 and 50893, two advanced breeding lines, produced about the same grain yield but differed markedly in the concentration of grain N (Fossati, Fossati & Feil, 1993, Euphytica 71, p. 115–123). Research on wheat and other cereals has shown that concentrations of protein and minerals are often positively correlated. Therefore, it appears likely that high-protein triticales, such as entry 50728, will also exhibit elevated levels of minerals. Grain of entries 50728 and 50893, from our experimental site Changins, were used to test this hypothesis. The kernels were assayed for a number of nutritionally relevant mineral elements (P, K, Mg, Mn, Ca, Fe, Zn, and Cu) by ICP-AES. Averaged over the two cropping periods, 50728 grain was clearly higher in N, P, K, Ca, and Fe and slightly higher in Mg and Zn than those of entry 50893. There were no differences between the entries for Mn and Cu.

As expected it appear that the grain of high-protein triticales may show increased levels of many mineral elements.
