Resumen
Sweetpotato (Ipomoea batatas (L.) Lam.) is an hexaploid specie (2n=6x=90) with high
levels of heterozygosity, it is an important tropical American crop belonging to the
family Convolvulaceae (Austin and Huaman, 1996), which has wide variations in
botanical characteristics and are readily distinguished on the basis of morphological
traits, yield potential, size, shape, fresh and skin colour of roots, as well as sizes,
colours and shapes of leaves and branches (Acheampong, 2012; Zhang et al.,
2000).Morphological characterization has been used as a first step in assessment
plant diversity for both plant genetic resources conservation and utilization
(Mwanga et al., 2017). In thi study, new phenomic approaches were used to
increase the e ciency discriminating di erent phenotypes not detected by
conventional morphological descriptors. Sweetpotato (Ipomoea batatas (L.) Lam.) is an hexaploid specie (2n=6x=90) with high
