He was also not a scientist. He had no training, education, and could barely read and write. He as was pulling it all out of his ass. He was a conman and very mentally ill.
“More than 3,000 mainstream biologists were dismissed or imprisoned, and numerous scientists were executed in the Soviet campaign headed by Lysenko to suppress scientific opponents. The president of the Soviet Agriculture Academy, Nikolai Vavilov, who had been Lysenko's mentor, but later denounced him, was sent to prison and died there, while Soviet genetics research was effectively destroyed. Research and teaching in the fields of neurophysiology, cell biology, and many other biological disciplines were harmed or banned.“

“After the appointment of Lysenko as head of the Soviet Academy of Agricultural Sciences, classical genetics began to be publicly called "fascist science"
