The lively debate of the impact of crossbreeding on evolution and plant breeding that gripped scientists in the late 19th and early 20th centuries is covered in this book. Plant scientists of the time were observing increases in plant size and vigor through crossbreeding, and pondering on the larger evolutionary implications of these observations. Scientists such as Darwin and Focke were also interested in the converse situation of inbreeding, and were curious as to whether inbreeding had the negative effects on health and vigor that they had observed in humans and other animals. This book draws upon the work of these scientists and the author's own extensive experiments with maize and the genus Nicotiana to provide a robust examination of these phenomena, proposing that the vigor of crossbred plants is due to heterozygosis, while the reduced vigor of inbred plants results from the elimination of heterozygous genes. The book provides a timely review of a pivotal topic in the history of plant science that is still as relevant and intriguing to scientists today as it was 100 years ago.
