PROBLEM TO BE SOLVED: To provide a novel and practical method for breeding cucurbit plants hard to be bred by cuttage, by increasing a rooting rate of cuttage and thereby improving a rate of taking root, vegetative growth, and reproductive growth after transplantation. SOLUTION: The method for promoting rooting of cucurbit plants by cuttage comprises the following process: cutting a cucurbit plant to obtain a cut vine (comprising terminal bud, cannon, and node) of the cucurbit plant as a scion, soaking the cut-off base portion of the cutting in a chitosan solution or dust coating chitosan-containing powder diluted with talc followed by planting the scion in a nursery bed, or pre-treating the cut-off base portion of the scion using a chitosan followed by treating again the pre-treated cut-off base portion of the scion again using auxins, or alternatively, followed by treating the thus pre-treated cut-off base portion of the scion using a solution or dust each containing a chitosan and auxins, and thereafter planting the resultant cutting in a nursery bed.
