Resistance to jassids in cotton is related to following character of cotton

Options

A. Morphological
B. Physiological
C. Biochemical
D. Biochemical and physiological

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the character of cotton that is related to its resistance to jassids, which are pests that attack cotton plants.

2. **Identifying Jassids:**
Jassids are insects that belong to the category of pests. They have a sucking nature, meaning they feed on the nutrients and juices of the cotton plant, which can lead to the plant's decline or death.

3. **Cotton Plant's Defense Mechanism:**
To protect against jassids, cotton plants have developed certain features. One notable feature is the presence of hair-like structures on the plant. These structures serve as a physical barrier to deter jassids from feeding on the plant.

4. **Classifying the Character:**
The hair-like structures on the cotton plant are classified as a morphological feature. Morphological characteristics refer to the physical traits and structures of an organism.

5. **Evaluating the Options:**
The options provided are:
- Morphological
- Physiological
- Biochemical
- Biochemical and Physiological

Since the resistance to jassids is related to the physical structure of the cotton plant (the hair-like extensions), the correct answer is "morphological."

6. **Conclusion:**
Therefore, the resistance to jassids in cotton is primarily related to its morphological characteristics.

**Final Answer:**
The correct answer is **morphological**.
