Method of producing herbicide resistant plant varieties and plants produced thereby

摘要

A method of introducing cytoplasmically inherited traits from a donor plant into a receptor plant of the Solanaceae family has been invented. A method is provided for producing Solanum tuberosum plants which have the inherited trait. 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 recpetor cytoplasmic traits are discarded.
