Abstract

A comparison of different measures to calculate resistance against late blight in potato was accomplished by means of the multivariate statistical tool of cluster analysis. One group of measures was based on the BLUP technique (Best Linear Unbiased Prediction). The measure rAUDPC_3, which takes into consideration the maturity group of the respective genotype, is recommended to capture maturity-corrected resistance, because of less theoretical assumptions with otherwise similar behaviour as compared to the rest of the measures.
