Question

‘Himgiri’ a variety of Wheat is resistant to

• A. White rust
• B. Bacterial blight
• C. Leaf and stripe rust
• D. Mosaic viruses

Answer 1

The correct option is C Leaf and stripe rust

White rust
White rust is a fungal disease caused by $Albugocandida$ that mainly affects plants like cauliflower belonging to the genus Brassica. This disease usually does not affect wheat varieties.

Mosaic viruses
Mosaic viruses are a group of viruses that cause the leaves of infected plants to have a mottled appearance. Himgiri is not resistant to mosaic viruses.

Bacterial blight
Bacterial blight is caused by $Pseudomonassyringae$. The main symptom of this disease is the development of brown necrotic leaf spots with yellow halos. The disease is caused by sowing infected seeds within a field.

Leaf and stripe rust
Leaf and stripe rust are fungal diseases of wheat where the infected tissue becomes brown and dry. Leaf rust is caused by the pathogen $Pucciniatriticina$ and stripe rust by $Pucciniastriiformis$. These diseases result in reducing the yield of crops. The Himgiri variety of wheat, developed through hybridisation, is resistant to leaf and stripe rust fungal diseases.
