Genetic Characterization of Weedy Rices and the Inference on their Origins.
Japanese Journal of Breeding, 1997 Weedy rice is defined as rice plants growing as weeds in and around the arable lands. Various forms of weedy rice were observed in many rice growing countries, but are decreasing under intensive cultivation system. Origin of weedy form and its significance in rice domestication are the interesting but unsolved problems for rice evolutionists.
