Summary The herbage of seven ryegrass clones, growing in the field as spaced clones in a randomised layout, was analysed for twelve mineral constituents. Significant differences in mineral composition of the clones were obtained for all minerals except potassium; nitrate, sulphate, and sodium showed the largest differences. The clones showed significant heritabilities for all the differences in mineral content except potassium; the extent to which these were due to additive genetic effects was not determined. In the case of nitrate, differences between clones persisted for twelve months. Interrelationships between differences in mineral composition, root cation-exchange capacities and herbage growth differences were examined. Total correlations were first calculated and then separated into genetic and environmental correlations, a number of which were significant. The most notable were genetic correlations between root cation-exchange capacities and five mineral constituents (iron, aluminium, titanium, nitrate, and acid-soluble phosphorus). No genetic correlations were found between growth and mineral differences.
