According to the basic information such as origin, agricultural characters of different germplasm,444 representative domestic cultivars,belonging to 13 species or varieties,7 genus of cucurbitaceae respectively,were selected as experimental materials to identify their resistance to root-knot nematode using the inoculation method of infected soil.Results showed the resistance distribution of different cucurbit crops.Omitting the discrepancy of different genotype,the average disease indexes in the same crop were in turn of wax gourd,watermelon,towel gourd,chieh qua,balsam pear,oriental pickling melon,melon,bottle gourd,cucumber,pumpkin,winter squash,summer squash.Through identification,27 accessions of germplasm with resistance to root-knot nematode were obtained,including 12 accessions of wax gourd,3 accessions of balsam pear,7 accessions of towel gourd and 5 accessions of watermelon.
