Which of the following breeding methods is also known as modified pedigree method?
Show Hint
Remember breeding methods in self-pollinated crops:
- Pedigree method: Individual selection from F2 onwards
- SSD (Single Seed Descent): Modified pedigree method
- Bulk method: Bulk population without selection
- Mass selection: Selection based on phenotype
- Pure line selection: Selection of best pure line
SSD is efficient for handling large populations.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
This question tests knowledge of plant breeding methods.
Step 2: Detailed Explanation:
S.S.D (Single Seed Descent) method is also known as the modified pedigree method.
Characteristics of SSD:
- A single seed is taken from each plant in each generation.
- Selection is delayed until later generations (F5-F6).
- Reduces time and space requirements.
- Suitable for self-pollinated crops.
- Also called "bulk pedigree method" or "modified bulk method".
Other breeding methods:
- Mass pedigree method (B): Not a standard term.
- Line breeding (C): A different method focusing on maintaining specific lines.
- Bulk pedigree method (D): Another term for SSD.
Thus, SSD is the modified pedigree method.
Step 3: Final Answer:
Thus, the breeding method known as modified pedigree method is S.S.D, which corresponds to option (A).
