Clonal populations regenerated from single-leaf cell protoplasts of the potato cultivar ;Russet Burbank' display a high frequency of variation for several horticultural and disease resistance characters. Observations over a period of three tuber generations suggest stable changes in tuber shape, yield, and maturity date, in photo-period requirements for flowering, and in plant morphology. Enhanced resistance to early blight (Alternaria solani) and late blight (Phytophthora infestans) diseases also regularly occurs within regenerated populations. These findings are discussed in the context of possible application to varietal improvement, particularly as they pertain to asexually propagated plants.
从马铃薯品种“Russet Burbank”的单细胞原生质体再生的克隆群体表现出多种园艺和抗病特性的高频变异。在三个块茎世代的观察期内，观察到块茎形状、产量和成熟期、开花的光周期需求以及植物形态的稳定变化。再生群体中也经常出现对早疫病（茄链格孢菌）和晚疫病（致病疫霉）的增强抗性。这些发现结合可能的品种改良应用进行了讨论，特别是与无性繁殖植物有关。
