| Abstract: | Resistance to the aphid Sitobion avenae F. was assessed on six wheat cultivars of known concentrations of total hydroxamic acids. A range of values for intrinsic rate of increase (rm) were obtained, 96% of the variation in which was explained by acid concentrations. Of the components of rm, age-specific fecundity was the most significant factor contributing to resistance. |
