Performance of rotation A and B along three generations.

A and B are the highlighted sequences in Fig 4. Rotation A is the sequence that maximises yield over multiple generations. Rotation B maximises yield in the first generation but not in the subsequent. For each rotation and generation there are shown values for total yield, final soil quality and final frequency of the most virulent strain (p5).图4中高亮标注的序列分别为A与B。处理轮换A是在多代实验中实现产量最大化的序列；处理轮换B仅在第一代实验中达成产量最大化目标，后续世代则未达到该水平。针对每一种处理轮换与每一个实验世代，均给出了总产量、最终土壤质量以及最强致病力菌株（p5）的最终出现频率。
