Detailed explanation-1: -Budding and grafting are asexual or vegetative techniques used to maintain the cultivated varieties (cultivars) nearly all of which are clones. Due to open pollination, more than 99 percent of all seedlings grown from clones bear fruit that is inferior to that produced by the parent trees.

Detailed explanation-2: -This is the most common and widely used form of vegetative propagation. Grafting – Grafting is propagation by combining a scion of one plant and connecting it to the stock of another. This form of propagation is primarily used with woody plants. There are many forms of grafts that can be done for many purposes.

Detailed explanation-3: -Grafting is a method of asexual plant propagation that joins plant parts from different plants together so they will heal and grow as one plant.

Detailed explanation-4: -Whip and Tongue Graft The whip and tongue technique (Figure 6) is most commonly used to graft nursery crops or woody ornamentals. Both the rootstock and scion should be of equal size and preferably no more than 1⁄2-inch in diameter.
