This paper analyzed the cadmium contents in different parts of oriental melon and fruit quality
through cultivating melon on the land with cadmium polluted soil．Results showed that in all 12 tested different
types of melon fruit，the cadmium contents were lower than that set by The National Food Safety Standards，Limit
of Contaminants in Food，GB 2762—2012 requested the cadmium content in melon fruit was 0.05 mg·kg-1．
The cadmium content in fruits of IVF-28 was the lowest，only 0.015 3 mg·kg-1．The cadmium distribution in
melon plant was：base stem and leaf ＞ root ＞ upper stem and leaf ＞ fruit．Integrating cadmium content and
fruit quality traits，we screened out IVF-28 suitable for planting in moderate and below heavy metal polluted
areas．
