Abstract: The genotypic differences of nitrate content in 46 pak2choi cultivars were studied during winter of 1998 and spring, summer, autumn of 1999. The results showed that there were significant differences of nitrate content among different cultivars of pak-choi. The cultivars of high and low nitrate content have been grouped by cluster analysis based on the experiment of four seasons. The result also showed that the nitrate content of the same
cultivar in different seasons was different. The nitrate content in spring and summer was higher than that in autumn and winter.

Key words: Pak-choi, Nitrate content, Genotypic difference, Season
