The right to apply for new varieties of plants is a right enjoyed by the breeder or the assignee of the right to apply for new varieties with novelty, specificity, consistency and stability. This right has both the property content in the field of private law and the procedural content in the field of public law. China's legislation does not clearly stipulate that the right to apply for new varieties of plants can be pledged, but the property, transferability and particularity of the right does not affect its pledge is beyond doubt.
