Production of virus-free lilies

Acta Horticulturae (36): 235-239

Production of virus-free lilies

Virus-free lilies were obtained by culturing 5-mm2 pieces of inner bulb scale on Sheridan's medium. The resulting plantlets were planted into a pasteurized soil-peat mixture and assayed for virus content; 47% did not contain detectable virus particles. Within a year 787 virus-free plants were obtained from one bulb 3 cm in diameter. Plantlets obtained by culturing 5 mm2 pieces of inner bulb scale on Sheridan's medium were planted in a pasteurized soil-peat mixture.

Highly tolerant hyacinth cvs, King of the Blues, Queen of the Pinks and Nobel, were freed from hyacinth mosaic virus.

Distribution indicated that in the latter year aphid transmission had occurred due to inadequate oil coverage.
