Solanum tuberosum L. Gp. Tuberosum populations that had been recurrently selected for resistance to potato leafhopper,Empoascafabae (Harris), were tested for levels of foliar solanidine glycosides. Leafhopper infestation level was 57% lower than for the unselected population after seven generations of selection. The mean concentrations of foliar solanidine glycosides significantly (P<05) increased from 40 mg/100 g fresh weight (fw) in the unselected population to 65 mg/100 g fw in the population developed from seven generations of selection for leafhopper resistance. The linear relationship between the level of leafhopper infestation and the concentration of foliar solanidine glycosides among population means was significant (P<01) and negative (r=−0.85).

Poblaciones deSolanum tuberosum L. Gp. Tuberosum que habían sido repetidamente seleccionadas paira resistencia a la cigarrita de la papa,Empoascafabae (Harris), fueron probadas para niveles foliaires de glicósidos de solanidina. Después de siete generaciones de selección el nivel de infestación de la cigarrita fue 57% más bajo que para las poblaciones no seleccionadas. Las concentraciones medias de glicósidos de solanidina incrementaron significativamente (P<,05), de 40 mg/100 g de peso fresco (pf) en las poblaciones no seleccionadas, a 65 mg /100 g de pf en la población desarrollada en las siete generaciones de selección para resistencia a la cigarrita. La relación lineal entre el nivel de infestación de la cigarrita y la concentración foliar de glicósidos de solanidina entre las medias de las poblaciones fue significativa (P<,01) y negativa (r=−0,85).
