Abstract
Abstract Tomato aspermy virus was found in chrysanthemum in New Zealand for the first time, in commercial gardens in Christchurch, Wanganui, and Auckland. The virus was transferred experimentally to marigold, nasturtium, aster, capsicum, chrysanthemum, tamarillo, lettuce, tomato, Nicotiana glutinosa L., Chenopodium amaranticolor Coste & Reyn., tobacco, black nightshade. New Zealand spinach, and zinnia. The longevity of the virus was between 7 and 11 days and the thermal inactivation point between 65° and 70°c. The dilution end point of the virus was between 1–50 000 and 1–100 000. The virus was transmitted by the green peach aphid.
