Concept:Banana plants are propagated vegetatively, mainly by using suckers that grow from the underground stem called rhizome.
Explanation:Most cultivated banana varieties are seedless, so they cannot be grown from seeds.
The banana plant has a reduced underground stem (rhizome) that bears several buds.
Each bud grows into a new plant called a sucker, which has its own pseudostem and rhizome.
These suckers emerge from the base of the main stem or directly from the corm.
Farmers select healthy suckers that are free from insects and leaf mottling, with narrow tapering leaves.
The sucker is separated and planted to produce a new banana plant.
Thus, commercial propagation of banana is done by suckers, not by stem cuttings, leaves, or seeds.
Banana belongs to the family Musaceae and genus Musa.
