The estimate of the heritability of resistance based on the relative Area Under the Disease Progress Curve (rAUDPC) according to Cullis et al. (2016) for each trial is shown.

The trial design does not have complete replicates. Therefore, the theoretical replication number is calculated as the harmonic mean of the number of replications across all genotypes.

RCBD, randomized complete block design; CRD, completely randomized design.
