The agronomist whose Michurinist agrobiology dominated Soviet biology for three decades
"The Central Committee of the Party has examined my report and approved it" — closing speech at the August 1948 VASKhNIL session. With that one sentence, classical genetics was banned across the Soviet Union.
Soviet agronomist of Ukrainian peasant origin. His vernalization technique brought him to prominence and from the mid-1930s he dominated Soviet biology. Attacking Mendelian genetics as bourgeois pseudoscience and championing the inheritance of acquired characteristics, he won a decisive victory at the August 1948 VASKhNIL session that banned classical genetics nationwide. He also proposed practical agrotechniques: summer potato planting, millet cultivation. Awarded three Stalin Prizes, eight Orders of Lenin, and Hero of Socialist Labor (1945). Removed in 1965 after Khrushchev's fall; died in Moscow in 1976. Never a party member.

Michurinist Agrobiology: Theory, Institutionalization, and the Bifurcation of Soviet Biology
The core of Lysenko's doctrine was the 'theory of stadial development of plants.' He held that higher plants must pass through several developmental stages before bearing seed, with each stage requiring specific environmental conditions: temperature, light, and their timing. From this theory he derived his practical agrotechniques: vernalization, summer potato planting, and cotton topping. The stadial theory itself was recognized even by opponents such as N. I. Vavilov and P. M. Zhukovsky as a genuine scientific contribution in its early formulation.
But Lysenko's theoretical ambition went further. He branded Mendelian-Morganist genetics as 'bourgeois pseudoscience' and rejected gene and chromosome theory outright. In its place he championed the inheritance of acquired characteristics: by altering environmental conditions, he claimed, one could 'train' the hereditary nature of plants in a desired direction. The practical consequence was the accelerated rollout of insufficiently tested varieties, the hollowing out of varietal trial procedures, and the systematic targeting of orthodox geneticists, above all Vavilov.
Lysenko's position strengthened rapidly after he publicly staked it out in his 1936 report 'On Two Directions in Genetics' at the fourth VASKhNIL session. He became president of VASKhNIL in 1938, and after Vavilov's arrest in 1940 he also assumed the directorship of the Institute of Genetics of the USSR Academy of Sciences. The climax came at the August 1948 VASKhNIL session. In his closing speech Lysenko declared that 'the Central Committee of the Party has examined my report and approved it': a statement that, under Stalin's patronage, banned the teaching and research of Mendelian genetics across the Soviet Union. Hundreds of geneticists were dismissed; even plant virus research withered, causing tangible damage to potato and grain production. Soviet biology diverged from the global scientific mainstream for decades, a bifurcation that began to be repaired only after Lysenko's removal in 1965, following Khrushchev's fall.
