Here is a compact definition of Lysenkoism from the educational site After Darwin:

In the U.S.S.R. of the 1930s, Trofim D. Lysenko rose to considerable power by claiming that his version of genetics, rather than that of Mendel and Darwin, could assist in the development of socialist ideology. If each successive generation of citizens had to be educated in Marxist ideology, he claimed, the utopia they envisioned would take too long to be realised. Rather, Lysenko rejected Mendelian heredity as bourgeois, and interpreted Marx as stating that man and nature are improvable and perfectable. He claimed, for example, that a winter wheat could be changed to a spring variety simply by altering the temperature at which it was grown, and that, by similar means, he could change wheat into rye in one generation. Darwin¹s struggle for existence, too, was dismissed as a bourgeois tool used to justify competition-based capitalist society. His erroneous assertions dominated Soviet biology for 30 years. He was eventually ousted, in 1965, due to rampant crop failures and shortages. Lysenkoism has come to represent the devestating consequences of marrying science to ideology.
