Abstract：In order to investigate the effect of salt stress on different pumpkin varieties,86 pumpkin varieties which belonged to four types:C.moschata,C.maxima,C.pepo and C.maxima × C.moschata were used in this research.The seedlings were treated by 240 mmol· L-1 NaCl at single-leaf stage.The results showed that'HM14'displayed the least salt damage (3.13％),the salt damage index of C.pepo was significantly higher than that of C.maxima and C.moschata.The above-ground part fresh weight,plant height,root length and relative chlorophyll content were analyzed,salt tolerance was found the highest variation coefficient (47.88％).As a conclusion,Cucurbita germplasm had high genetic diversity,which could provide a possibility to seek for a salt tolerant pumpkin type.
