Abstract:It is basis for rich in parent materials on breeding of special utilized sweetpotato new varieties that pay attention to evaluation on special utilized sweetpotato germplasm resources. 76 Special utilized Sweetpotato germplasm with high content of carotene from CIP were evaluated, the results are as follows: 2 accessions with short-vine characteristics, 19 ones with higher dry matter rate than Xushu18 (CK), 3 ones have the dry matter content in excess of 30%, 19 ones have carotene content ≥ 10 mg/100 g fresh weight, the fresh root weight of 440189 is higher than CK. Accessions with resistance to black-rot, root rot, rot-nematode were obtained 44, 10, 26 respectively, and 20 accessions are resistant to any two diseases of black-rot, root rot, rot-nematode, 5 ones are resistant to 3 kinds of disease.
