The research revealed that glufosinate resistance can be transferred from transgenic rice to weedy rice, with significant implications for agronomic performance and weed management. Hybrid populations of transgenic glufosinate-resistant rice and weedy rice exhibited similar plant vigor, density, and seed dormancy compared to non-transgenic populations. The gene flow from transgenic rice to weedy rice occurred at low frequencies but was sufficient to confer herbicide resistance. Additionally, the agronomic performance of hybrids was comparable to that of weedy rice parents, indicating that gene flow could occur under natural conditions. Although glufosinate-tolerant rice has the potential for breeding and crop improvement, it also presents significant challenges for weedy rice management. Effective management strategies are essential to mitigate the risk of herbicide-resistant weedy rice populations and ensure the sustainable use of transgenic herbicide technologies. This review aimed to evaluate the breeding potential and challenges associated with glufosinate-tolerant rice, understand the genetic and agronomic consequences of transferring glufosinate resistance from transgenic rice to weedy rice and assessing the implications for weed management and crop improvement.
