 Advantages of asexual propagation

1. There is a good adaptation of crops.

4. Crops are uniformly established.
5. They can stand more adverse environmental conditions e.g poor soil
6. Seedless crops can be propagated.
7. The offsprings are always identical to the parent plant.
8. Many flowers or ornamental plants are easily grown with the method.

1. Planting materials cannot be stored for a long period of time without losing their viability.
2. Diseases of parent stock are manifested in offspring.
3. Vegetative materials are costly, especially tree crops.
4. It requires special skills or expertise.
5. The plant lodge very readily.
6. The process involved in the preparation of the vegetative material may be time-consuming.
7. Vegetative materials are generally bulky making their transportation and handling difficult.
