There is substantial evidence indicating that many weedy rice forms originated from or are closely related to cultivated rice. There is suspicion that the outbreak of weedy rice in China may be related to widely grown hybrid rice due to its heterosis and the diversity of its(More)
Gene flow from transgenic rice to weedy and cultivated rice is a key biosafety consideration.
