Micrografting is used to produce plants free from Correct Answer Virus

Micrografting is used to produce plants free from viruses.
An innovative technique of micrografting was developed by Murashige et al. (1972) for the production of uniform virus-free plants on a commercial scale in a controlled environment.
They grafted a small apical shoot of citrus to the top of a decapitated seedling grown in vitro. Micropropagation can be used to produce disease-free plants. It produces rooted plantlets ready for growth, and saves time for the grower, instead of seeds or cuttings.
