      abstract = {In order to find out the difference in cadmium tolerance  of different rice varieties in central Hunan, 26 varieties  of conventional rice, two-line hybrid rice and three-line  hybrid rice were used as materials. The effects of cadmium  stress（0.5 mmol/L）on germination percentage, germination  index, vigor index, root length, bud length and fresh  weight of root buds of rice seeds were studied by indoor  bioassay. The results showed that cadmium stress had little  effect on seed germination rate and germination index of  different rice varieties, but had obvious effect on vigor  index, root and bud growth, and the inhibitory effect of  cadmium stress on root was significantly greater than that  on bud. There were some differences in the mean values of  six indexes among different types of rice varieties, but  the differences were not significant. The tolerance  responses of 26 varieties to cadmium stress were quite  different. According to the cluster analysis of  comprehensive effects of stress, they could be divided into  three types: sensitive type, intermediate type and tolerant  type. Among them, the sensitive rice varieties were  Xiangwanxian 16, Y Liangyou 9918, C Liangyou 651 and Xin  You 215, accounting for 15.38% of the total tested  varieties; the tolerant varieties were Y Liangyou 1 and  Neixiang 2128, accounting for 7.69% of the tested  varieties; the other varieties fell within tolerant  intermediate type, accounting for 76.92%. },
