摘要

Sweet potato is infested by root-knot and reinform nematodes. Root-knot nematode infestation in sweet potato is studied in detail. A number of resistant varieties are released in sweet potato from USA, Japan and China. A number of germplasm accessionsand cultivars/ varieties were found resistant to the nematodes in Peru. Studies carried out by the authors indicated that sweet potato germplasm is resistant to root-knot nematode in general and susceptibility is less. 'Sree Bhadra', a high yielding variety of sweet potato is found as a resistant trap crop of root-knot nematode. Pratylenchus and Ditylenchus are also known to cause serious damage in Japan and China, respectively. However, they are not serious in India and it is desirable to be quarantined in India.
