Question

"Pusa Sadabahar" is resistant to _______ disease.

• A. Leaf curl and chilli mosaic virus
• B. Leaf and stripe rust
• C. Black
• D. Curl blight black rot

Hint:

To combat crop losses from pathogens, the Indian Agricultural Research Institute (IARI) has developed disease-resistant crop varieties, like the 'Pusa Sadabahar' chilli plant. This perennial chilli plant, producing for up to three years, resists leaf curl virus and chilli mosaic virus. Leaf curl causes upward curling and yellowing of leaves, while the mosaic virus leads to a mosaic pattern, yellowing, mottling, and leaf deformation.

Answer 1

The Correct Option is A

The correct option is (A): Leaf curl and Chili mosaic virus

Answer 2

Explanation:

Crops often face losses due to various infectious diseases caused by pathogens. So, to combat these losses, the Indian Agricultural Research Institute (IARI) has developed many disease-resistant crop varieties through conventional plant breeding programs. One notable example is the ‘Pusa Sadabahar’

•  Pusa Sadabahar is a variety of Chilli plant.
•  It is a perennial plant that produces chilli for three years in a row if cared for properly.
• It is resistant to the virus that causes leaf curl and chilli mosaic virus. These are the two diseases caused by chilli pepper plants.
• Chilli leaf curl is an infectious disease which causes the leaves to curl or roll upwards, it leads to stunted growth and yellowing of the leaves. 
• On the other hand, the chilli mosaic virus develops a mosaic pattern on the leaf. 
• It causes yellowing, mottling and leaf deformation
