Abstract: The method of adjusting plot values by covariance on neighbouring plots is applied to the analysis of plant breeding trials. For cereal trials the method is shown to be very effective in reducing variation caused by spatial heterogeneity within replicates and generally performed about as well as a more conventional row and column lattice square analysis. Results obtained from trials with replicated standards suggest that the reduction in estimate of error variance truly reflects the increased accuracy of the estimates of variety means. The method may be used when plot values are affected by the particular varieties occurring in neighbouring plots, and is effective in adjusting for competition effects in sugar beet trials.
