Abstract In order to screen and utilize the common bean resources resistant to common bacterial
blight，this paper identified and evaluated the disease resistance of 151 accessions core germplasm of common
bean in Shanxi by puncture inoculation method on the opposite true leaves，and conducted cluster analysis on
resistant germplasm．The results showed that puncture inoculation of the opposite true leaves could be used
as a rapid and effective method for identification of disease resistance．Through identification，there were 35
resistant and moderate resistant germplasms out of 151 resources，accounting for 23.2% of the total，and 116
susceptible or highly susceptible germplasms，accounting for 76.8% of the total．The only disease resistant
germplasm ‘F0001696’could be used as a high-quality parent material for the improvement and creation
of red kidney bean．Clustering analysis divided the 35 moderate resistant or above core germplasms into 3
groups．The first group included 19 germplasms with short growth period，dwarf plant height and mainly erect
determinate growth．The second group included 4 germplasms with longer growth period，tall plant height
and indeterminate trailing growth．The third group included 12 germplasms with long growth period，medium
plant height and trailing or semi-trailing indeterminate growth．
