| Abstract: |
| In order to ascertain the relationship between the different stages in the formation of tuber structures and the morphological charaters of the above-ground parts of several important released varieties of sweet potat in North China,to ascertain varieties difference or simi- larity,and to find out new approaches in the improvement of the method of appraisal of sweet potatoes varieties breeding,a series of studied was planned to be carried out.This study,however,are limi- ted only to the following:1.Observat... |
