Droopy plant type is not a favourable attribute<br />

Within mixed population of 40 cv’s<br />

Yield w<br />

<strong>Weed</strong> <strong>biomass</strong><br />

Erectness 0.71** − 0.68**<br />

Within japonica germplasm of 23 cv’s<br />

Yield w<br />

<strong>Weed</strong> <strong>biomass</strong><br />

Erectness 0.50* − 0.64*<br />

A more erect plant type was correlated with higher yields (more even light<br />

distribution in the canopy). Surprisingly there was no penalty regarding WSA,<br />

as erectness was associated with a lower amount of weed <strong>biomass</strong>.
