Norin -10 gene is famous for

Options

A. Gigas effect
B. Dwarfing effect
C. Aromatic effect
D. Early maturation effect

Answer

**Step-by-Step Solution:**

1. **Understanding the Norin-10 Gene**: The Norin-10 gene is a significant gene in plant breeding, particularly in wheat. It is known for its role in developing semi-dwarf varieties of wheat.

2. **Identifying the Effects**: The question provides four options: Giga's effect, dwarfing effect, aromatic effect, and early maturation effect. We need to determine which of these is associated with the Norin-10 gene.

3. **Analyzing the Dwarfing Effect**: The dwarfing effect refers to the phenomenon where plants exhibit reduced height compared to their normal size. The Norin-10 gene is specifically known for inducing this dwarfing effect in wheat plants.

4. **Examining Other Options**:
- **Giga's Effect**: This effect involves an increase in nuclear DNA volume, leading to larger cell and organ sizes. This is unrelated to the Norin-10 gene.
- **Aromatic Effect**: This pertains to the aromatic properties of compounds, which is not relevant to the Norin-10 gene.
- **Early Maturation Effect**: This effect relates to the timing of plant maturity, which is also not associated with the Norin-10 gene.

5. **Concluding the Correct Answer**: Given that the Norin-10 gene is known for its role in creating semi-dwarf wheat varieties, the correct answer is the dwarfing effect.

**Final Answer**: The Norin-10 gene is famous for the dwarfing effect.
