Añadir al carritoPaperback. Condición: New. Print on Demand. This book was written after the author spent years comparing two maize-breeding methods, one relying on inbreeding, and the other on cross-fertilization within a varied population. In the course of the experiments, the author noticed various growth problems in the first method of breeding. They observed that while inbreeding itself could eliminate many growth issues, it also resulted in uniform plants that were less resistant to disease and environmental stress. By comparing the two methods, the author ultimately contends that genetic diversity and crossbreeding are more effective at producing high yields than the isolation of homozygous strains. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
