Explanation

2. The traditional breeding techniques also failed to provide fast and efficient systems for crop improvement.
(b) The advantages are as under:
1. A very large number of plants can be grown in a short period of time.
2. Micropropagation allows growth of healthy plants from diseased ones using meristem culture
(c) It has been commercially adopted in the following ways :
1. For commercial production of tomato banana and apple.
2. Meristem culture has been used for recovery of healthy plants of potato and sugarcane from diseased plants.
