Georgii Karpechenko

From Wikipedia, the free encyclopedia

Georgii Dmitrievich Karpechenko (1899 - July 28, 1941) was a Russian and Soviet biologist.

Worked on cytology and invented 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 experimental crossbreeding.[1].[2][3][4]

He was arrested by the NKVD under the false grounds of belonging to an alleged "anti-Soviet group" centered around the well known Russian botanist Nikolai Vavilov. He was sentenced to death and executed on July 28, 1941.
