Abstract: Resent years Melon root-rotten (,i>Cucumis melo) has been seriously happened in melon cultivation both in greenhouse and in field. We collected the typical diseased plants，isolated and identified the pathogen，the result of morphological investigations of the isolate from the diseased plants indicate that it is Fusarium solani(Mart.) Sacc. that causes Melon root-rotten. Use this pathogen to evaluate the resistance of 267 melon materials in lab，using seeding inoculation method. The result shows that 16 materials obtained from 267 C.melo var. chinensis materials were highly resistant to melon root-rotten; 20 materials were resistant. The result of seeding inoculation indicate there are available resistance resources in C.melo var. chinensis . This resistance resources could be used in melon root-rotten of melon resistance breeding.

Key words: C.melo, Root-rotten, Pathogen isolation, Resistance evaluation
