Abstract

Two leaf-spot- and spider-mite-resistant varieties of sugar beets, GW 674 and GW 359, exhibited resistance to the development of populations of the sugar-beet root aphid, P. betae. GW 674 is a selection of GW 359 but has higher sugar content and greater leaf-spot resistance. Nine other varieties were susceptible to root aphid infestations.
