- Abstract
Añu is an underutilized Andean crop. Its tuber has the potentiality to be used in the food and pharmaceutical industries due its glucosinolates content and antioxidant capacity. However, añu could be facing potential problems such as loss of variability due to low consumption. For this reason, in this study 89 accessions collected from 9 districts in the Cusco region were characterized and their morphological variability was determined. The characters used in the morphological characterization were assessed for use their by the coefficient of variability, correlation and principal component analysis. The flower and tubers characters best assess the variability of the germplasm. In the cluster analysis using 31 characters, 89 morphotypes were determined distributed into 4 groups with a distance coefficient of 1.45. Groups I and II have yellow and orange tubers, while Groups III and IV have red gray, purple gray and black tubers. The absence of duplicates, suggests that despite its clonal reproduction and its underutilization, añu still maintains a wide morphological variability in Cusco Region.
