  • Under the Trait, the number of observations and unique genotypes analyzed is given in brackets. Variance of zero indicates that variance was <1e−03. Narrow sense heritability (h2) is calculated from the BLUP values of genotypes and genotypic variance. Spatial structure is given with the direction and the parameter value in brackets. Chi-square statistic is calculated from the log likelihood values (LLk) of the Base and selected Model 1 is given with p-value in brackets. The table shows results from trial-trait analysis with significant improvement in fit of Model 1 over Base at α = 0.1. Percentage change in pCOR and pRMSE for Model 1 compared to Base after CV are given.
