Question

Resistance to yellow mosaic virus and powdery mildew were induced by mutations in:

• A. Cotton
• B. Maize
• C. Bhendi
• D. Mung bean

Hint:

{Key Distinction:}

• {Mung Bean:} Resistance induced by {Mutation}.
• {Parbhani Kranti (Bhendi):} Resistance derived from {Wild Species}.

Answer 1

The Correct Option is D

Step 1: Understanding Mutation Breeding:
Mutation breeding involves inducing mutations (using chemicals or radiation like gamma rays) to create new desirable traits, such as disease resistance, in plants.
Step 2: Specific Example from Curriculum:
A classic example provided in biology textbooks (e.g., NCERT Class 12) is the induction of resistance in Mung bean to Yellow Mosaic Virus (YMV) and Powdery Mildew through mutation breeding.
Step 3: Other Options:
(C) Bhendi (Okra): Resistance to YMV in Bhendi (\Abelmoschus esculentus) was transferred from a wild species resulting in a new variety called \Parbhani Kranti (Conventional breeding/Interspecific hybridization, not primarily mutation breeding in the classic textbook context).
Step 4: Final Answer:
The correct option is (D).
