There several advantages and limitations of breeding clonally propagated species:

Advantages

 Sterility is not a factor in clonal propagation because seed is not involved.

 Because clonal plants are homogeneous, the commercial product is uniform.

 Micropropagation can be used to rapidly multiply planting material.

 Heterozygosity and heterosis are fixed in clonal populations.

Disadvantages

 Clonal propagules are often bulky to handle (e.g. stems, bulbs).

 Clones are susceptible to devastation by an epidemic. Because all plants in the clonal population are identical, they are susceptible to the same strain of pathogen.

 Clonal propagules are difficult to store for a long time, because they are generally fresh and succulent materials.
