Abstract:: Thirty-eight bitter gourd varieties were used as materials,24 traits were investigated by field trail and lab test.The Shannon′s information index (H′) was used to evaluate the genetic polymorphism evaluation of each characteristic,in order to provide reference for genetic improvement of Momordica charantia L.The results showed that these traits varied at different extent among accessions in Momordica charantia L.The diversity index(H′) varied from 0.515 to 1.351 of quality traits,and that of melon shape，melon color and melon edge size of them were all higher than 1,whereas the diversity index(H′)of the quantitative characteristics varied from 1.893 to 2.260,among them seven quantitative characteristics such as petiole length，leaf length,leaf width,fruit length,fruit thickness,vitamin C content and protein content were higher than 2.In addition,there was no significant correlation between each two indices such as dry matter content,vitamin C content,soluble protein content,flavonoid content and saponin content.
