Abstract
Many of the most important floral and nursery crops are vegetatively propagated.
Production of these crops involves a scale-up in production that often begins with a single plant or a few progeny that are selected for superior horticultural value.
Many years ago, producers of nuclear stock realized the importance of certifying the foundation plants free of all known pests and disease organisms.
Production of healthy nuclear stock has been achieved in several major crops such as carnation, chrysanthemum, orchids, roses, freesias, bulbous iris, lilies and several minor bulb crops.
In some instances, commercial selections have been maintained as clean stock by producing plants in a protected environment.
In other instances, when the newly introduced cultivars have become infected, it has been possible to free plants of
