Grouping of 21 Botrytis cinerea epidemics based on disease assessment in vineyards and as predicted based on the discriminant function analysis (DFA) using model output as discriminant variables.

a Real group membership is based on disease incidence (DI) and severity (DS) of Botrytis rot assessed in the vineyards at maturity. Mild, DI b In cross validation, each case is classified by the functions derived from all cases other than that case.c Group membership predicted by the DFA.Grouping of 21 Botrytis cinerea epidemics based on disease assessment in vineyards and as predicted based on the discriminant function analysis (DFA) using model output as discriminant variables.
