Which crop variety is bred specifically for resistance to bacterial blight?
APusa Shubhra (cauliflower)
BPusa Komal (cowpea)
CPusa Sawani (lady's finger)
DPusa Gaurav (brassica)
Answer & Solution
Correct answer: B. Pusa Komal (cowpea)
1. The disease-resistance table pairs each variety with its target disease.
2. Pusa Komal, a cowpea variety, is listed against bacterial blight.
3. Pusa Shubhra resists black rot, while Pusa Sawani and Pusa Gaurav are insect/pest-resistant, not disease-resistant.
4. Hence the answer is B.
