Question:
Given below are two statements:
Statement (I): Bringing together two or more genes governing a single trait, especially resistance to disease is known as gene pyramiding
Statement II: The use of molecular markers greatly facilitates gene pyramiding as it minimises the need for disease tests and progeny test
In light of the above statements, choose the most appropriate answer from the options given below:

In light of the above statements, choose the most appropriate answer from the options given below:
Show Hint
Gene pyramiding is highly effective for developing durable host plant resistance, which is less likely to break down due to pathogen mutations.

- Both Statement (I) and Statement (II) are true.
- Both Statement (I) and Statement (II) are false.
- Statement (I) is true but Statement (II) is false.
- Statement (I) is false but Statement (II) is true.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Gene pyramiding is a crop breeding strategy designed to accumulate multiple genes governing resistance to a particular pathogen into a single cultivar.
Step 2: Detailed Explanation:
Statement I is true because gene pyramiding is specifically defined as the assembly of multiple genes targeting a single trait (such as multi-race disease resistance).
Statement II is true because marker-assisted selection (MAS) allows breeders to verify the presence of multiple genes without needing extensive phenotypic pathogen-challenge assays, making pyramiding fast and efficient.
Step 3: Final Answer:
Both Statement I and Statement II are correct.
