Sanjay, a research scholar wants to develop a desired variety of Guava in his orchard. Which of the following methods of vegetative propagation will be the most suitable for him?
- Cutting
- Grafting
- Layering
- Micropropagation
Answer
Grafting
Reason — Grafting is the most suitable method for developing a desired variety of guava as it can combine desirable qualities of two plants of the same or related species.
Cutting is not very reliable for guava. Layering is possible but less efficient for large-scale improvement. Micropropagation is advanced and costly, mainly used in labs.
