During five years (1976 to 1980), at La Platina Experiment Station (INIA), Santiago, Chile, field trials and glasshouse tests were conducted to study the effect of BYDV and aphidvectors on different wheat cultivars. Results indicated a reduced effect of the aphids and BYDV in 1979 and 1980, with respectto 1976, 1977, and 1978, when yield losses were over 15%. Cultivars V-19, Aurifén and Anza showed the best behaviors.
