Those tissue cultured Banana's are really healty!!!
Propagating banana's from suckers is a waste of time!!! If you take a sucker from a diseased mother plant...the sucker will be contaminated and thus the growth rate and production will be poor!!!
From a single diseased free and certified sucker, you will be able to produce 200 identical clones of superior quality...insteed of 1 plant from a single sucker!!!
