What is the Major Advantage of Producing Plants by Micropropagation - Biology


What is the major advantage of producing plants by micropropagation?



Micropropagation is a method of producing new plants in a short duration using plant tissue culture.

Some major advantages of micropropagation are as follows:

(a) Micropropagation helps in the propagation of a large number of plants in a short span of time.

(b) The plants produced are identical to the mother plant.

(c) It leads to the production of healthier plantlets, which exhibit better disease-resisting powers.
