A school of pseudoscience that flourished in the Soviet Union from the early 1930s tothe mid-1960s, in violent opposition to traditional biology. The founder was T. D. Lysenko. He proclaimed a revolutionary fusion of agronomy and biological science, and therefore called his creation agrobiology, not Lysenkoism, the term that was used by his opponents.
A coherent outline of Lysenko's doctrines is hardly possible. The inheritance of acquired characters is often considered his central doctrine, though he came to it belatedly, as an offshoot of his original concept: “vernalization,” or iarovizatsiia, a wordthat he coined. At first he used the word to describe the transformation of winter-habited wheat into spring habit as a result of moistening and chilling the seed before planting. He denounced the specialists who told him that the phenomenon had been observed and studied long before he put a new name on it, and he went on to extend the new term to almost any kind of seed treatment, and also to a stage in plant development that he claimed to have discovered. Lysenko came into conflict with scientific plant breeders and geneticists when he applied his concept of vernalization to hybridization and the selection of improved varieties. He came to endorse some ofthe crudest versions of the ancient belief in the inheritance of acquired characters. For example, he declared that domesticated plants are transformed into weeds by the hostile environment of poorly tended fields. See also Genetics; Organic evolution; Vernalization.

Lysenkoism was a set of repressive political and social campaigns in science and agriculture by the powerful Stalinist director of the Soviet Lenin All-Union Institute of Agricultural Sciences, Trofim Denisovich Lysenko and his followers, which began in the late 1920s and formally ended in 1964.
Lysenkoism, or Lysenko-Michurinism, may also denote the biological inheritance principle which Lysenko subscribed to and which derive from theories of the heritability of acquired characteristics, a body of biological inheritance theory which departs from Mendelism and that Lysenko named "Michurinism".

In 1928, Trofim Lysenko, a previously unknown agronomist, claimed to have developed an agricultural technique, termed vernalization, which tripled or quadrupled crop yield by exposing wheat seed to high humidity and low temperature. While cold and moisture exposure are a normal part of the life cycle of fall-seeded winter cereals, the vernalization technique claimed to enhance yields by increasing the intensity of exposure, in some cases planting soaked seeds directly into the snow cover of frozen fields. In reality, the technique was neither new (it was known since 1854, and was extensively studied during the previous twenty years), nor did it produce the yields he promised.
When Lysenko began his fieldwork in the Soviet Union of the 1930s, the agriculture of the Soviet Union was in a massive crisis due to the forced collectivization movement.
Many agronomists were educated before the revolution, and even many of those educated afterwards did not agree with the collectivization policies. Furthermore, among biologists of the day, the most popular topic was not agriculture at all, but the new genetics that was emerging out of studies of Drosophila melanogaster, commonly known as fruit flies. Drosophilidae fruit flies made experimental verification of genetics theories, such as Mendelian ratios and heritability, much easier. Only much later would this research have obvious application to the problem of agriculture, so during the 1920s and 1930s it was easy for a radical like Lysenko to castigate these theoretical biologists for spending their time bent over trays of fruit flies while famine raged on around them.
Isaak Izrailevich Prezent, a main Lysenko theorist, presented Lysenko in Soviet mass-media as a genius who had developed a new, revolutionary agricultural technique. In this period, Soviet propaganda often focused on inspirational stories of peasants who, through their own canny ability and intelligence, came up with solutions to practical problems. Lysenko's widespread popularity provided him a platform to denounce theoretical genetics and to promote his own agricultural practices. He was, in turn, supported by the Soviet propaganda machine, which overstated his successes and omitted mention of his failures. Instead of making controlled experiments, Lysenko relied upon questionnaires taken of farmers to claim that vernalization increased wheat yields by 15%.
Lysenko's political success was due in part to his striking differences from most biologists at the time. He was from a peasant family, and an enthusiastic advocate of the Soviet Union and Leninism. During a period which saw a series of man-made agricultural disasters, he was also extremely fast in responding to problems, although not with real solutions. Whenever the Party announced plans to plant a new crop or cultivate a new area, Lysenko had immediate practical suggestions on how to proceed.
So quickly did he develop his prescriptions - from the cold treatment of grain, to the plucking of leaves from cotton plants, to the cluster planting of trees, to unusual fertilizer mixes - that academic biologists did not have time to demonstrate that one technique was valueless or harmful before a new one was adopted. The Party-controlled newspapers inevitably applauded Lysenko's "practical" efforts and questioned the motives of his critics. Lysenko's "revolution in agriculture" had a powerful propaganda advantage over the academics, who urged the patience and observation required for science.
Lysenko was admitted into the hierarchy of the Communist Party of the Soviet Union, and was put in charge of agricultural affairs. He used his position to denounce biologists as "fly-lovers and people haters," and to decry the "wreckers" in biology, whom he claimed were trying to purposely disable the Soviet economy and cause it to fail. Furthermore, he denied the distinction between theoretical and applied biology.
Following the disastrous collectivization efforts of the late 1920s, one of USSR's greatest agricultural problems during the 1930s was that many peasants were thoroughly unhappy with the collectivization. Lysenko's 'new' methods were seen as a way to make peasants feel positively involved in an 'agricultural revolution'. The party officials believed that peasants planting grain — for whatever reason — was a step in the right direction and a step away from the days when peasants would destroy grain to keep it from the Soviet government. Academic geneticists could not hope to provide such simple and immediately tangible results, and so were seen as politically less useful than the charlatanism of Lysenko.
Lysenko did not apply actual science. He was a proponent of the ideas of Ivan Vladimirovich Michurin, and practiced a form of Lamarckism, insisting on the change in species among plants through hybridization and grafting, as well as a variety of other non-genetic techniques. With this came, most importantly, the implication that acquired characteristics of an organism — for example, the state of being leafless as a result of having been plucked — could be inherited by that organism's descendants.
It is often suggested that Lysenko's success came solely from the desire in the USSR to assert that heredity had only a limited role in human development; that future generations, living under socialism, would be purged of their 'bourgeois' or 'fascist' instincts. But Lysenko himself never purported that his views could be applied to human biology; they were relegated strictly to agriculture. He indeed attacked certain reductionist views of heredity, like eugenics, but only as bourgeois influences on science. Many scholarly works on Lysenkoism agree that it was not based on human genetics. Stalin, however, wanted to believe that Lysenkoism did apply to human genetics.
Lysenkoism's success was also not wholly ideological — it did not follow just from Marxist or Leninist philosophies that supposedly rejected certain ideas about human determinism on ideological grounds. Historians, such as Loren Graham (of the Massachusetts Institute of Technology), David Joravsky (formerly at Northwestern University) have argued that the success was more due to Soviet political maneuvers at the time than to an attempt to replace the basic tenets of science.
Nevertheless, there is no doubt that rival views were rejected because they were seen as 'bourgeois' or 'fascist', and analogous 'non-bourgeois' theories also flourished in other fields in the Soviet academy at this time (see Japhetic theory; socialist realism). Interestingly, perhaps the only opponents of Lysenkoism during Stalin's lifetime to escape liquidation came from the small community of Soviet nuclear physicists. But as Tony Judt has observed, "Stalin left his nuclear physicists alone... [He] may well have been mad but he was not stupid."[1]

From 1934 to 1940, under Lysenko's admonitions and with Stalin's approval, many geneticists were executed (including Isaak Agol, Solomon Levit, Grigorii Levitskii, Georgii Karpechenko and Georgii Nadson) or sent to labor camps. The famous Soviet geneticist Nikolai Vavilov was arrested in 1940 and died in prison in 1943).[2].
Genetics was stigmatized as a 'bourgeois science' or 'fascist science' (because fascists — particularly the Nazis in Germany — embraced genetics and attempted to use it to justify their theories on eugenics and the master race, which culminated in Action T4).
If the field of genetics' connection to Nazisms wasn't enough, Mendelian genetics particularly enraged Stalin and other atheists due to its founder Gregor Mendel's being a Priest, a fact that flew in the face of the Marxist ideology that religion was backwards and evil[citation needed].
Despite the ban, some Soviet scientists continued to work in genetics, dangerous as it was[citation needed].
In 1948, genetics was officially declared "a bourgeois pseudoscience"; all geneticists were fired from work (some were also arrested), and all genetic research was discontinued. Nikita Khrushchev, who claimed to be an expert in agricultural science, also valued Lysenko as a great scientist, and the taboo on genetics continued (but all geneticists were released or rehabilitated posthumously). The ban was only waived in the mid 1960s.
Thus, Lysenkoism caused serious, long-term harm to Soviet biology. It represented a serious failure of the early Soviet leadership to find real solutions to agricultural problems, allowing their system to be hijacked by a charlatan — at the expense of many human lives. Lysenkoism also spread to China, where it continued long after it was eventually denounced by the Soviets[citation needed].
Almost alone among Western scientists, John Desmond Bernal, Professor of Physics at Birkbeck College, University of London and a Fellowship, made an aggressive public defense of Lysenko and some years later gave an obituary of ‘Stalin as a Scientist.’ However, despite Bernal's endorsement, other members of Britain's scientific community retreated from open support of the Soviet Union, and may have been one of the chief reasons for a retreat from Marxism in that country[citation needed].
The word 'Neo-Lysenkoism' has occasionally been invoked as a derogatory term in the debates over race and intelligence and sociobiology against scientists minimizing the role of genes in shaping human behavior, such as Leon Kamin, Richard Lewontin, Stephen Jay Gould and Barry Mehler.[3][4]
