The experiment was conducted in the greenhouse of Hongyang Farm in Shanghai．Six
conventional cultivated pakchoi〔Brassica campestris L. ssp. chinensis（L.）Makino var. communist Tsen et
Lee〕cultivars were used to carry out comparative trial on clubroot resistance and to measure partial physiological
indicators between the susceptive and normal plants．The results showed that the disease indexes of‘Chaoyue
808’and‘Fusheng 218’were more than 30．They were susceptible．The disease indexes of‘Qingyang’and‘Ji
npinxialian’were 10-20．They were resistant．The disease index of‘Chaoyue 909’was less than 10．It showed
high resistance．The disease index of‘Jinpinlyuyoumei’was 0，it was immune．The leaf length，leaf width，
plant height，chlorophyll content，soluble protein content and Na+ content in root of the susceptible pakchoi plants
were lower than that of the normal plants among the 6 tested normal pakchoi cultivars．However，the contents of
soluble sugar，K+ content and K+/Na+ ratio in root were significantly higher than that of the normal plants．The
results of testing each physiological indicators showed that‘Jinpinlyuyoumei’could be used as major cultivar and
assisting breeding material in Shanghai area.
