In the free exposition system the highest values of these parameters with 77%, 0.15 and 1,573, respectively, were obtained however, the introductions LA1480 and LA2075 showed the lowest values under this production system.Ĭhromista phylogenetic resources severity solanaceae rate of disease development area under the disease progress curve. According to the analysis, under the semi cover system the lowest numerical values for final severity, r and AUDPC, with 47%, 0.09 and 1,133, was obtained, respectively standing out the introductions LA1480, IAC1686, LA2131 and LA2692. Finally, an analysis of variance and Duncan's tests was conducted. The potato pathogen Phytophthora infestans, the causal agent of potato late blight, is the plant pathogen that has most greatly impacted humanity to date.This pathogen is best known for its causal involvement in the Irish potato famine after introduction of the HERB-1 strain to Ireland from the Americas in the 19th century (). In addition, the regression coefficients of the evaluated variables was calculated. ![]() The evaluated variables were: severity (%), rate of disease development (r) and area under the disease progress curve (AUDPC) of late blight. Split plots was the experimental design used, being the main plots the production systems, and the subplots, the tomato introductions, with four replications. The study was conducted with fifteen wild tomato introductions at the Montelindo's farm of the Universidad de Caldas, in two production systems: free exposition and semi cover. To reach this purpose, it is necessary to carry out epidemiological studies and evaluate wild introductions against tomato late blight caused by Phytophthora infestans, the most devastating disease worldwide. Hence, it is necessary to evaluate and identify promising wild genotypes to observe their reaction to the main pathological problems of cultivated species, in order to be considered in future programs of tomato production improvement. Most of the genes responsible of resistance of tomato to fungi, bacteria, virus and nematodes, has been derivate from wild species of tomato.
