(A) Specific leaf area (average over measurement levels), (B) LOV, (C) LAI, and (D) photosynthetic rate at flowering measured on three plants per plot from 10 different hybrids, which were released in the period between 1971 and 2012 and either grown in 2015 or 2016. S = slope of the regression. The regression indicates differences among hybrids across the year of registration. All slopes were tested to be significantly different from zero. Significance levels are: ***p < 0.001 and **p < 0.01, R2 = pseudo R2. Values are averages from three plants per plot with three blocks.
