What was the name of Mendel's paper that introduced his laws?

Mendel’s paper that introduced his laws was titled Versuche über Pflanzenhybriden.

The German title means “Experiments on Plant Hybridization.” Mendel presented the work to the Natural History Society of Brno at meetings on February 8 and March 8, 1865. It was published the following year in the society’s proceedings, where it attracted little immediate attention.

The paper described years of carefully controlled crosses involving garden peas. Mendel tracked traits such as seed color, seed shape, flower color, and plant height, then counted the traits appearing in successive generations. From these numerical patterns, he proposed that inherited characteristics were transmitted as discrete units—ideas now expressed through genes and alleles.

The English translation is a description of the title, not the original title itself. “Experiments on Plant Hybridization” is therefore a reasonable translation but not the paper’s canonical German name. Mendel’s conclusions later became associated with the laws of segregation, dominance, and independent assortment, although the modern vocabulary of genetics did not yet exist when he wrote.
