Crop improvement was considered as a branch of science only after the

Options

A. Proposal of laws of inheritance by Mendel
B. Discovery of mutation by Hugo de Vries
C. Development of Mutation breeding by Muller & Stadler
D. Rediscovery of Mendel law of heredity in 1900.

Answer

**Step-by-Step Solution:**

1. **Understanding Crop Improvement**: Crop improvement refers to the scientific methods used to enhance the quality and yield of food crops. This includes developing new varieties of crops that are more productive, resilient, and nutritious.

2. **Historical Context**: The concept of crop improvement has been practiced for centuries through selective breeding. However, it was not recognized as a formal branch of science until specific scientific principles were established.

3. **Mendel's Contribution**: Gregor Mendel, in the 19th century, conducted experiments on pea plants and discovered the fundamental laws of inheritance. His work laid the foundation for understanding how traits are passed from one generation to the next.

4. **Rediscovery of Mendel's Laws**: Although Mendel's work was published in 1866, it was largely ignored until it was rediscovered in the early 20th century. This rediscovery provided a scientific basis for crop improvement, allowing scientists to apply genetic principles to agriculture.

5. **Conclusion**: Therefore, crop improvement was considered a branch of science primarily after the rediscovery of Mendel's laws of heredity in the 19th century.

**Final Answer**: Crop improvement was considered as a branch of science only after the rediscovery of Mendel's laws of heredity in the 19th century.
