Micheletto, R. Boland, M. Huarte] Abstract : Greenhouse and field evaluations of quantitative resistance to late blight in genotypes of the wild Argentine diploid species Solanum chacoense, Solanum commersonnii, Solanum microdontum and Solanum maglia were performed with a complex race containing the virulence factors 1, 3, 4, 5, 7,10, 11 of Phytophora infestans and using the percentage of leaf area affected by late blight estimated at weekly intervals. From these readings the area under the disease progress curve (AUDPC) was calculated. Highly resistant and susceptible genotypes were identified. Resistance and variability were found in S. chacoense, which together with S. commersonnii showed a significantly higher level of resistance compared to the susceptible checks. Field evaluations of an F1 progeny of 165 individuals, obtained from non-inbred diploid parents segregating for foliage quantitative resistance in S. chacoense, were also done by means of AUDPC. The polygenic nature of the resistance and some indication of the presence of both additive and interaction effects were evident.
