Feral rice from introgression of weedy rice genes into transgenic herbicide-resistant hybrid-rice progeny

摘要

Cultivation of glufosinate-resistant transgenic rice varieties, hybrid rice (F1), and their succeeding generations (F2–F4) over 3 years in plots adjacent to weedy-rice fields demonstrates that the segregating progeny of transgenic hybrid rice pollinated by weedy rice can rapidly derive into weedy forms carrying the transgene.
