Abstract：In this study，in-door seedling-inoculation method was used to identify the resistance of 16 cultivars and 84 germplasm resources collected from Heilongjiang against Acidovorax avenae. Among the 10 watermelon cultivars，‘Xinhongbao’，‘Jingxin No.1’，‘Shuangkangdadilei’，‘Tedaqinghongbao’，‘Chaofeng F1’ and‘ Qingfa No.7’ were mid-resistant，‘Jingfengbao’ and‘Qihongxigua’ were mid-susceptible，and‘ Jifu No.2’，‘Qingnong No.1’ were susceptible. Among the 6 melon cultivars，‘Qitian No.1’，‘Yongtian No.3’and‘Longtian No.3’ were mid-resistant，‘Ribentianbao’ and‘ Longtian No.1’were moderate susceptible，and‘ Bentian No.3’ was susceptible.No high resistant and immune cultivar was found in watermelon and melon cultivars. Among the 49 melon germplasms the resistant resources accounted for 57.1%. X11-3，X11-1 and X11-8 were high resistant. Among the 35 watermelon germplasms，the resistant resources accounted for 48.6%，11W005 and 11W003 were high resistant.
