Mean PSC increased following each generation of recurrent selection in F1, F2 and F3 Nemesia strumosa families derived from a cross of a 100% PSC plant to an unrelated 0% PSC plant. The first 100% PSC individuals occurred in the F4. Populations derived through sib pollination tended to have higher PSC means than lines derived through self pollination. One F3 family showed a three-fold higher PSC level when pollinated in the green-house than when pollinated in the growth chamber, while another F3 family similarly pollinated showed no change in PSC.
在从一个 100% PSC 植株与一个无关联的 0% PSC 植株的杂交后代的 F1、F2 和 F3 风铃草属植物家系中，每次进行回交选择后，PSC 的平均值都有所增加。在 F4 中首次出现了 100% PSC 个体。通过姊妹交授粉产生的群体的 PSC 平均值往往高于通过自交授粉产生的品系。一个 F3 家系在温室授粉时的 PSC 水平比在生长室授粉时高出三倍，而另一个同样授粉的 F3 家系的 PSC 则没有变化。
