Abstract: In order to screen out the new cassava cultivars, the paper identified the 13 cassava lines based on the agronomic traits. The results showed that, there were rich diversities among the 13 cassava lines, shown as the shape of leaf, the color of the leaf, the number of lobes, the color of leaf vein, the color of the petiole, the inner and outside skin color of the stem, the color of the young stem, the plant type, the branch, the height, the diameter of the stem, the distribution of tuber, the shape of the tuber, the inner and outside skin color of the tuber, the color of the root, as well as harvest index, the starch and dry matter content of tuber. This work evaluated 13 cassava genotypes systematically, screened out 5 excellent new lines, and provided the reference for the classification of cassava germplasms.
