Karpechenko G. D.

Georgii Dmitrievich Karpechenko (1899, Velsk, Vologda Governorate – July 28, 1941) was a Russian and Soviet biologist. His name has sometimes been transliterated as Karpetschenko.

G. D. Karpechenko specialized in plant cytology and created several hybrids. Among his contributions is his seminal work on allopolyploids, culminating in his creation of a fertile offspring of radishes and cabbages, the first instance of a new species obtained through polyploid speciation during experimental crossbreeding.
