Predictions of seed weight and seed number per ear. Comparison of a virtual total seed weight per ear with actual total seed weight per ear and b comparison of virtual seed number per ear (seeds > 2.0 mm) with actual seed number of per ear. Under drought, 125 out of the 143 plants produced seeds above 2.0 mm, under combined drought and heat only 38 out of the 148 plants produced seeds of > 2.0 mm of size. r2, correlation coefficient
