Multivariate analyses reveal the classification of Lepidium spp. in Peru.

Lepidium is a genus that is distributed within the Andean region of Peru and includes L. meyenii which is the cultivated species. To date, there is a lack of knowledge regarding the classification of Lepidium germplasm from Peru. In order to characterize this germplasm, a collection was made in the Peruvian Andes across 12 departments of the country located between 1800 to 4600 meters above sea level, obtaining 289 accessions in total. These entries were grown in the greenhouse and field and then we scored 28 quantitative and 51 qualitative morphological descriptors of the plant, leaves, stems, flowers, roots, seeds and fruits. Principal component analysis demonstrated that the first two components (CP1 and CP2) summarized 85.2% of the total morphological variability, CP1 (70.4%) was highly correlated (0.90 Lepidium spp. Our next step is to conduct molecular work on this germplasm employing NGS techniques.
