Phenotypic data for aggressiveness components of Puccinia triticina isolates on bread wheat varieties that compensate for a virulence deficiency and scripts for statistical analysis with R

Aggressiveness of a plant pathogen can be defined as the quantitative variation of pathogenicity on a compatible host and is measured by evaluating quantitative traits expressed during the host–pathogen interaction, i.e. the components of aggressiveness. The most widely assessed aggressiveness components for rust pathogens are infection efficiency (IE), latency period (LP) and sporulation capacity (SP). Puccinia triticina is a fungal pathogen responsible of the wheat leaf rust disease. We measured the three aforementioned aggressiveness components for 23 P. triticina isolates representative of the most frequent pathotype-genotype combination (named ‘pathogenotype’) 106 314 0-G2 and 166 317 0-G1. The evaluations were realized on seedlings of different bread wheat varieties. This dataset is composed of .XLSX data files corresponding to the three aggressiveness components and .R text files containing the scripts used in the software R for statistical analysis.
