Abstract
Five viruses have been isolated from Narcissus tazetta cv.
Grand Soleil d’Or : tomato black ring, strawberry latent ringspot, arabis mosaic, cucumber mosaic and narcissus degeneration viruses.
No virus-free plants were found in cultivation.
Plants infected with arabis mosaic and narcissus degeneration viruses were freed from virus by meristem-tip culture.
Virus-free bulbs grew more vigorously than infected ones and gave more and larger flowers with a better colour.
To accelarate the multiplication of virus-free stock various methods of propagation were tried.
Multiplication using chips consisting of parts of two or three bulb scales plus basal plate gave an overall rate of c.4 x per annum.
A scheme has been organised to replant the Isles of Scilly with virus-free bulbs, requiring 20 million bulbs by 1978. The work is being done in collaboration with the Nuclear Stock Association (Ornamentals) Ltd. and will be a pilot scheme for a much larger project with virus-free trumpet daffodils.
