Tissue culture technique can produce infinite number of newe plants from a small parental tissue. The economic importance of the technique is in raising:

Options

A. genetically uniform population identical to the original parent
B. homozygous diploid plants
C. new species
D. variants through picking up somaclonal varoation

Answer

**Step-by-Step Solution:**

1. **Understanding Tissue Culture Technique**: Tissue culture is a method used to grow plants in a controlled environment using small pieces of plant tissue, known as explants. This technique allows for the production of a large number of plants from a single parental tissue.

2. **Process of Micro-propagation**: The tissue culture technique often involves micro-propagation, where the explant is placed in a nutrient medium under sterile conditions. This leads to the development of new plants that are genetically identical to the parent plant.

3. **Genetic Uniformity**: One of the key advantages of tissue culture is that it produces genetically uniform populations. This means that all the new plants produced are clones of the original parent plant, ensuring consistency in traits such as growth rate, disease resistance, and yield.

4. **Evaluating the Options**:
- **Option 1: Genetically uniform population identical to the original parent** - This is correct as tissue culture produces clones that are genetically identical to the parent.
- **Option 2: Homozygous diploid plants** - This is incorrect because the plants produced can be haploid or diploid, depending on the source tissue.
- **Option 3: New species or variants** - This is incorrect as tissue culture does not inherently create new species or variants; it produces clones.
- **Option 4: New species or variants through picking up somaclonal variation** - This is also incorrect since somaclonal variation refers to genetic variations that can occur in tissue culture, but the primary purpose of tissue culture is to produce identical plants.

5. **Conclusion**: Based on the evaluation of the options, the economic importance of the tissue culture technique is in raising a genetically uniform population that is identical to the original parent.

**Final Answer**: The economic importance of the tissue culture technique is in raising a genetically uniform population identical to the original parent.
