Abstract
A method of introducing cytoplasmically inherited traits from a donor plant into a receptor plant of the Solanaceae family has been invented. Protoplasts from the donor and receptor plants are prepared. The donor protoplasts are treated under suitable conditions to prevent extensive nuclear divisions. The treated donor protoplasts and receptor protoplasts are then contacted under suitable conditions permitting the fusion of the protoplasts. Plantlets are regenerated from the fused protoplasts, and plantlets which contain the donor cytoplasmic traits are selected and rooted. Plantlets which contain receptor cytoplasmic traits are discarded.
