Oxalis tuberosa is a vegetatively propagated tuber crop in the Andes. The peasants cultivate a great number of varieties for which genetic homogeneity has never been demonstrated. Morphological descriptors and ISSR markers were used to determine the intra-varietal diversity and the influence of the mode of conservation ex-situ vs in-situ. Molecular markers revealed an intra-varietal genetic diversity attesting that oca varieties are not pure clones. The morphological analysis was congruent with… CONTINUE READING
