Abstract:Among the aphid-resistant alfalfa cultivars ‘Dawson,’ ‘Kanza,’ and ‘Washoe,’ 75.0, 71.1, and 42.4%, respectively, of the plants were resistant (resistant and intermediately resistant) to the spotted alfalfa aphid, Therioaphis maculata (Buckton). Also, 75.0, 65.4, and 53.9%, respectively, were resistant to the pea aphid, Acyrthosiphon pisum (Harris). The percentage of plants with combined resistance to both aphid species among these 3 cultivars was 59.6, 44.2, and 25.1, respectively.
