About this book
Species and Varieties, Their Origin by Mutation is by Hugo de Vries. The author’s preface says the purpose of these lectures is to point out the means and methods by which the origin of species and varieties may become an object for experimental inquiry. The lectures were delivered at the University of California.
The text says hereditary qualities are to be deduced from the composition of the progeny, and that two successive generations are often required for complete evidence. The text says pedigree-book-keeping must become the general rule. The text says lots of seed consisting only of tricotyls are very rare. The text says summer and winter varieties have been cultivated separately for centuries, but in trials it is often easy to convert the one into the other.
