Question

Select the mismatch from the following.

• A. Cotton – Hairy leaves – Resistance to aphids
• B. Wheat – Hairy leaves – Resistance to cereal leaf beetle
• C. Wheat – Solid stems – Resistance to stem sawfly
• D. Cotton – Smooth leaves – Resistance to bollworms

Answer 1

The correct option is A Cotton – Hairy leaves – Resistance to aphids

Insect resistance in host crop plants may be due to morphological, biochemical or physiological characteristics. Hairy leaves in cotton provide resistance to jassids and in wheat resistance to cereal leaf beetle. Solid stems in wheat provide resistance to stem sawfly and smooth leaved, nectar-less cotton varieties do not attract bollworms.
