A mosaic disease of Primula obconica caused by a potyvirus

Acta Horticulturae (59): 167-173

A mosaic disease of Primula obconica caused by a potyvirus

A virus, sporadically isolated since 1968 from P. obconica plants showing mosaic and flower colour-breaking, could be obtained from flowers only. An elongated virus of the potyvirus group, it infected a wide range of plant spp. (10 families) in experiments. It is aphid transmitted in a stylet-borne manner. The thermal inactivation point is 55 - 60 deg C, dilution end point 10-3 - 10-4, and longevity 15 days at room temp.

Details are given of the symptoms of this virus disease, which is transmitted by aphids. The symptoms disappeared completely when the plants were given 4 treatments at 5-10-day intervals with biomycin or an aqueous extract of male fern.
