To increase food supply, especially Musa species, harnessing genetic diversity and novel traits can result in developing new genotypes that are capable of withstanding changing environmental factors, since populations with narrower range may fail to survive climatic extremes. There are now very informative and cost‐effective molecular markers that target conserved domains and can effectively exploit the genetic indices or gene pools inherent in banana and plantain plants as well as their wild relatives for crop genetic improvement. It has been reported that structural variant genes possessing presence or absence of variants contribute to diversity of the gene pool (Golicz et al. 2016). Identification of Musa accessions (wild and elite ones) that can be adopted and optimized to perform in diverse environmental conditions based on abundant allelic diversity is very important, since the optimal development of these accessions is dependent on the allelic/genetic diversity (Montenegro et al. 2017). Knowledge of genetic diversity within accessions of Musa species with diverse genomic groups can facilitate the efficiency of breeding programs. Comparatively, assessing the effectiveness of different molecular markers is essential for identification of appropriate ones for genetic improvement and germplasm conservation.
