In Potato, self pollination is performed in
(a) Bud condition
(b) Cleistogamous condition
(c) Bending of filaments to bring anthers in contact with stigma
(d) Style bends to brings stigma in contact with anthers

Options

A. Bud condition
B. Cleistogamous condition
C. Bending of filaments to bring anthers in contact with stigma
D. Style bends to brings stigma in contact with anthers.

Answer

To solve the question regarding self-pollination in potatoes, we need to analyze each option provided:

1. **Understanding the Question**: The question asks in which condition self-pollination occurs in potatoes. We need to evaluate the options given.

2. **Option A: Bud Condition**: In this condition, the flower is not fully developed, and self-pollination does not occur. Therefore, this option is incorrect.

3. **Option B: Cleistogamous Condition**: This refers to flowers that do not open and thus cannot facilitate self-pollination. Since potatoes do not have cleistogamous flowers, this option is also incorrect.

4. **Option C: Bending of Filaments to Bring Anthers in Contact with Stigma**: This suggests that the filaments bend to facilitate pollination. However, in potatoes, it is not the filaments that bend but rather the style. Thus, this option is incorrect.

5. **Option D: Style Bends to Bring Stigma in Contact with Anthers**: In potatoes, the style curls, which allows the stigma to come into contact with the anthers, facilitating self-pollination. This is the correct option.

**Final Answer**: The correct answer is (d) Style bends to bring stigma in contact with anthers.
