Question:
In nature, most of the cultivated banana belongs to the group
In nature, most of the cultivated banana belongs to the group
Show Hint
Remember banana ploidy:
- Diploid (2n): Wild species, seeded
- Triploid (3n): Most cultivated (AAA, AAB, ABB)
- Tetraploid (4n): Some hybrids (AAAA)
- AAAA: Some breeding lines
Cavendish, Robusta, Grand Naine are triploid bananas.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
This question tests knowledge of banana ploidy levels.
Step 2: Detailed Explanation:
Most cultivated bananas are triploid (3n).
Cultivated bananas belong to the AAA (triploid) genome group.
Banana ploidy levels:
- Diploid (2n): AA (wild species), Musa acuminata.
- Triploid (3n): AAA (most cultivated, e.g., Cavendish, Robusta, Grand Naine).
- Tetraploid (4n): AAAA (some hybrids).
- Hexaploid (6n): Not common.
Triploid bananas are:
- Seedless (parthenocarpic).
- Larger fruits.
- Higher yield.
- Vegetatively propagated.
Thus, most cultivated bananas are triploid.
Step 3: Final Answer:
Thus, most cultivated bananas belong to the triploid group, which corresponds to option (B).
