Senescence kinetics over thermal time after anthesis for 199 wheat varieties grown with two post-flowering temperature treatments. The mean (curves) $\pm$ standard deviation (shaded areas) of the fitted logistic senescence curve calculated from a raw data for both years or b from gBLUP parameters are shown for all genotypes in stress (red) and no stress (blue) treatments. The red double-headed arrow represents the period during which the stressed plants were exposed to heat treatment
