Micropropagation is useful
(I) To generate someclonal variation which are exploited for crop improvement
(II) To multiply genetically uniform population
(III) To generate new species
(IV) Tp produce heterozygous plants

Options

A. I & III are correct
B. III & IV are correct
C. I & II are correct
D. II & III are correct

Answer

### Step-by-Step Solution:

1. **Understanding Micropropagation**: Micropropagation is a technique used in plant tissue culture to produce a large number of plants from a small amount of plant tissue. This process allows for the rapid multiplication of plants.

2. **Analyzing the Statements**:
- **(I) To generate some clonal variation which are exploited for crop improvement**: Micropropagation primarily produces clones of the parent plant, so it does not typically generate clonal variation.
- **(II) To multiply genetically uniform population**: This is a key advantage of micropropagation. It allows for the production of genetically identical plants, ensuring uniformity in traits.
- **(III) To generate new species**: Micropropagation does not directly create new species; it is mainly used for cloning existing species.
- **(IV) To produce heterozygous plants**: Micropropagation produces clones that are genetically uniform (homozygous), not heterozygous.

3. **Conclusion**: Based on the analysis, the most accurate statement regarding the usefulness of micropropagation is (II) - to multiply genetically uniform population.

### Final Answer:
Micropropagation is useful primarily for statement **(II)**: To multiply genetically uniform population.
