Abstract: Based on BSA (Bulk sergeant analysis) and comparative analysis, the paper focus on the effects of heredity background and foreign gene(s) on the variation of main agronomy traits with three F2 populations and DH population derived from hybridization of high generation transgenic rice and non-transgenic rice. And the results can be summarized as follow: the father’s genotype has a certain effect on the performance of agronomy traits; Compared with foreign gene not containing plants, the foreign gene containing plants in three F2 populations show degenerate trends in some main agronomy traits, such as longer days to heading, lower plant height, lower fertility and larger variation coefficient. But in DH population, although the variation coefficient of foreign gene containing lines is significantly higher than foreign gene not containing lines, there are no significant differences in the main agronomy traits between the two groups, which indicate tissue culture is the main reason of agronomy traits and the introduction of foreign gene(s) enlarged the chances of variation.
