Concept:
Hybrid varieties are developed by crossing two different parent varieties to combine desirable traits such as yield, taste, disease resistance, and adaptability.
Step 1: Understanding hybridization.
Hybridization involves controlled pollination between two selected parent plants to produce improved offspring.
Step 2: Identifying Amrapali mango.
Amrapali is a well-known dwarf hybrid mango variety developed in India.
Step 3: Parent varieties of Amrapali.
It is a cross between Dasheri and Neelum mango varieties.
Step 4: Evaluating the options.
- Dasheri $\times$ Langra $\rightarrow$ Not correct
- Dasheri $\times$ Neelum $\rightarrow$ Correct hybrid combination
- Alphonso $\times$ Kesar $\rightarrow$ Not correct
- Langra $\times$ Neelum $\rightarrow$ Not correct
Step 5: Additional insight.
Amrapali mango trees are dwarf in size, suitable for high-density planting, and produce regular and high yields with good fruit quality.
Step 6: Conclusion.
Thus, "Amrapali" is a hybrid of Dasheri and Neelum.
