Contrasting patterns of variation in weedy traits and unique crop features in divergent populations of US weedy rice ( <i>Oryza sativa sp</i> .) in Arkansas and California

Abstract

Recent de-domestication of weedy species - such as in California weedy rice - can involve trait combinations indistinguishable from the crop. This underscores the need for strict seed certification with genetic monitoring and proactive field inspection to prevent proliferation of weedy plant types. In established populations, tillage practice may affect weed diversity and persistence over time. © 2017 Society of Chemical Industry.
