Abstract: Selection of sweetpotato local resources of disease resistance and dry matter was the basis of breeding with multi-resistant, high-quality and high yielding. Identification of disease resistance and quality analysis of 850 sweetpotato local resources were carried out: 71 high-dry matter materials (dry matter ≥30%) were found, 5 high-dry matter materials resistance to three diseases, 23 materials (dry matter ≥30%) resistance to two diseases, 42 materials (dry matter ≥30%) resistance to one disease. Analysis of parent type about 254 varieties of sweetpotato showed that: 85.58% of 254 varieties selected variety (strain) as parents, 18.5% of 254 varieties selected foreign resources as parents, only 8.3% and 0.78% of total varieties selected local resources and wild resources as parents separately.
