In this paper, the effects of transgenes insertion on the outcross potentiality of rice varieties were assessed by pollen vigor and hybrid seed set. The in vitro pollen germination rates of five transgenic rice lines transformed respectively with bar, crylAb, BADH and Xa21 gene were investigated, and compared with their relative receptor rice varieties. The results showed that there existed a significant difference in in vitro pollen germination rates between receptor rice varieties, but no significant difference was found between transgenic rice varieties and their relative receptors. The in vitro pollen germination rate for transgenic rice varieties varied from 0.416 to 0.584, similar to that of their relative receptors (0.400-0.574). Investigation on the hybrid seed set of 26 hand-crosses showed that the inserted bar or crylAb gene had a significant effect on the hybrid seed set of receptors, while the effect of Xa21 gene was smaller. The hybrid seed set rate of non-transgenic rice in crosses with transgenic rice (pollen donor) was from 0.056 to 0.413, not different from that in crosses with their relative receptors (0.052-0.417). It's suggested that transgenes insertion had little effect on the outcross potentiality of rice varieties.
