Fig. 4 The relation between seed yield and residue production at harvest maturity. Both axes are inclusive of material dropped before and during harvesting. Solid lines represent the least squares regressions for three replicate plots of all genotypes except for the outlying cv. Laird plots (see text) which are represented by a cross within the symbols. The regression lines have the equations
for Pullman 1996,
for Pullman 1997 and
