Trofim Lysenko stands as a paradoxical figure in the history of science, a man whose innovative, practical contributions to developmental biology and agriculture are often overshadowed by his destructive role in Soviet genetic research. A fair appraisal reveals Lysenko, born into a peasant family on September 29, 1898, as one of the Soviet Union's most creative and logical founders of developmental biology. Despite only learning to read and write at age 13, his loyalty to the Bolsheviks facilitated an education and rapid ascent that would have otherwise been impossible, culminating in his training as an agronomist and early publications beginning in 1923.
Lysenko's work was rooted in practical application, exemplified by his early posting to Azerbaijan where he worked on legumes and later innovated grass-field crop rotations to improve soil fertility. This work was the foundation for his theory of the stage development of organisms. In 1927, he published his first paper on vernalization (iarovizatsiia), the technique of exposing seeds to cold and moisture to boost yields and resilience, a technology still used globally in breeding and production. His practical research evolved into a comprehensive, though flawed, theory of heredity and evolution he termed "Michurinism" or agrobiology, which strongly emphasized environmental factors.
Michurinism directly challenged the dominant Weismann and Morgan theories of formal genetics, which posited the stability and immutability of an inherited "germ plasm" and genes located on chromosomes. Lysenko objected to the "immortality" of genes, instead casting heredity as a dialectical interchange of cellular matter and its environment, where changes in an organism resulted from changes in its metabolism. His focus was on the "plant-environment" complex, diagnosing selection not merely as a fusion of genes but as an evaluation of factors influencing the formation of new, adaptive traits.
Lysenko's practical achievements were significant and enduring. His theory of stage development defined the ingenious technology of vernalization. He proposed nest planting with acorns to facilitate cooperation among plants in forestation projects. As director of the All-Union Selection and Genetics Institute, he pushed for breeding on a high agricultural background to create high-yielding, adaptive varieties, many of which remain popular today. He also devised methods like biological control of pests using chickens and championed direct sowing of grain crops into stubble to combat drought and winter kill, a technique now globally known as No-till farming. Lysenko's advocacy for natural, biological technologies stood in opposition to the chemicalization of agriculture, which he predicted would lead to environmental contamination. During the difficult war years, his recommended practices, such as planting potatoes with eyes and minimal pulp, saved millions of lives, while pile and trench storage organized quick, effective supply lines.
However, the destructive consequences of his political power cannot be overlooked. With the support of Joseph Stalin, Lysenko transformed his scientific views into "Lysenkoism," a political movement that rejected classical genetics—which he pejoratively dismissed as a "bourgeois invention"—in favor of an empiricist and metaphysical understanding of species change. This movement severely hampered Soviet biological research. Over 3,000 traditional biologists were reportedly dismissed, imprisoned, or executed during Stalin's great purge in the name of Lysenkoism. The most tragic victim was Lysenko's former mentor, the internationally respected geneticist Nikolai Vavilov, who was arrested in 1940 and died of malnutrition in captivity in 1943. Vavilov’s death was a profound loss for the genetics community. Although Lysenko's political dominance peaked in the 1940s, his methods were already being progressively abandoned in practical agriculture, with local bureaucrats returning to more effective techniques. This shift began even before Stalin’s death in 1953, signifying the slow but eventual rejection of Lysenkoist agrobiology, first in practice and then gradually in science.
