  1. Disease severity (DS); infection response (IR); coefficient of infection (CI); BLUEs, best linear unbiased estimate; σ2G estimate of genotypic variance; σ2E estimate of environmental variance; σ2GxE is the genotype by environment interaction variance, σ2 error is the residual error variance; heritability (H); r Pearson’s correlation coefficients among stem rust DS, IT, and CI between two seasons. *, **, *** and ns represents significance at P < 0.05, P < 0.01, P < 0.001, and not significant, respectively
