The Origin, Variation, Immunity and Breeding of Cultivated Plants

Nikolai Vavilov, a Soviet plant geneticist, conducted extensive global expeditions to study the origins of cultivated plants. His seminal work, The Origin, Variation, Immunity and Breeding of Cultivated Plants, proposed that a plant's center of origin is where its wild relatives exhibit the greatest adaptiveness and diversity. This research identified 13 world centers of plant origin, areas that have historically provided the majority of useful crop plants and domestic animals. Vavilov's work laid the groundwork for understanding plant variation and immunity, contributing significantly to the field of plant breeding. Despite his contributions, his research methods led to conflict with T.D. Lysenko, resulting in Vavilov's persecution.123
