Concept:
Mango (*Mangifera indica*) is the national fruit of India, and different regions are famous for specific cultivars based on agro-climatic suitability. Agribusiness students must know the Geographical Indication (GI) and regional associations of these varieties.
Step 1: Map the variety to the region.
Zardalu is a medium-sized mango variety known for its unique yellow color (hence the name "Zarda," meaning yellow) and pleasant aroma. It is the pride of Bihar (4), specifically the Bhagalpur district.
Step 2: Compare with other regions.
1. Maharashtra (2) is famous for Alphonso (Hapus).
2. Tamil Nadu (1) is known for Banganapalli and Neelum.
3. Punjab (3) produces Langra and Chausa, though they are more common in Uttar Pradesh.
Step 3: Verify economic importance.
Bhagalpur Zardalu Mango has been granted a Geographical Indication (GI) tag, highlighting its importance in the agricultural economy of Bihar.
