    In this work, the morphological characterization and the resistance to powdery mildew of eight kidney tomato cultivars (New Yorken, Rodade, Rosa de Berna, Lignon, Caraibo, LA1033, LA3863, Sheila), improved by INRA (National Institute of Agricultural Research) were evaluated. of France), for this it was carried out in the canton of Cuenca, province of Azuay, implanting the cultivation under plastic cover with a completely random design (DCA). The parameters measured in the trial were: emergence percentage, setting percentage, plant height, number of leaves, stem diameter, days to flowering, number of flowers per cluster, number of fruits per cluster, fruit weight, incidence and severity of powdery mildew. The LA1033 and LA3863 cultivars obtained 100% germination, while the yield for the Caraibo cultivar was the lowest with 78%, a lower value than the other varieties whose values were 100%, the LA 1033 cultivar presented higher foliage with an average of 14.44 leaves eighty days after transplanting. The LA3863 cultivar was the earliest for days to flowering with an average of 53.56 days. With regard to powdery mildew, infection occurred only in the Lignon and Rodade cultivars with a severity value of 1.98% for Lignon and 4.8% for Rodade, characterizing them as tolerant, however, the rest of the cultivars have immunity characteristics. in which they were not infected with powdery mildew, in addition, no fruiting was obtained for cultivars LA1033 and LA3863, so their use is not recommended for local conditions.
