The methods are
1. Grafting-It is a horticultural technique whereby tissues of plants are joined so as to continue their growth together.
2. Crossing-Crossing occurs when a plant breeder takes pollen from one plant and brushes it onto the pistil of a sexually compatible plant, producing a hybrid that carries genes from both parents. When the hybrid progeny reaches flowering maturity, it also may be used as a parent.
