Comparison of A. delicious and A. chinensis
In older classifications, A. delicious was considered a variety of A. chinensis, but since the 1980s, the two species have split based on characteristics including fruit shape, skin texture, and hairiness. In general, A. delicious is more oblong and cylindrical, while A. chinensis>/i> is rounder and more globe-shaped. A. delicious has a thicker skin covered with more and stouter hairs, while A. chinensis has a smoother, thinner skin, with hairs more like peach fuzz, which can be rubbed off easily. A. delicious is the source of the widely produced “Hayward” cultivar synonymous with kiwifruit, but cultivars of A. chinensis were developed starting in 1977 with commercial production starting in the 1990s; the fruit is marketed as “gold kiwifruit.”
