WSA and yielding ability are compatible Weed biomass Rice Yield Experiment 1 Experiment 2 Weed free yield − 0.67** Weedy yield − 0.84** − 0.76** The highest yielding cultivars, both in weedfree and weedy conditions, were best able to suppress weeds. This suggests that there is no tradeoff between WSA and yielding ability
How to select for early vigour? In field experiment: Visual score • Subjective • Requires sufficient seed Selection on individual plants Requirements • Easy quantifiable \ objective traits • Nondestructive observation Additional consideration: • Are weedsuppressive cultivars characterized by a specific growth strategy?
