Yield formation of Central-European winter wheat cultivars on a large scale perspective

Improvement of grain yield potential for winter wheat (Triticum aestivum) may become harder to achieve in the future because an increase of harvest index has been largely exploited by breeders. Therefore, it is of high interest to detect how the components of the yield equation GY = Q × LUE × HI (GY: grain yield, Q: radiation interception, LUE: light use efficiency, HI: harvest index) contribute to the explanation of yield differences of modern...
