Who was the greatest selective plant breeder of all time?

While many plant breeders have made significant contributions, Gregor Mendel is often regarded as one of the greatest selective plant breeders of all time. His pioneering work in the 19th century with pea plants established the foundational principles of heredity and genetics. Mendel's experiments laid the groundwork for modern genetics, influencing both plant breeding and agricultural practices. His insights into inheritance patterns revolutionized the understanding of how traits are passed down, making him a pivotal figure in the history of selective breeding.
