Paperback. Condizione: New. Print on Demand. This book provides a statistical framework for understanding seed testing, drawing on historical approaches to develop standards of precision for different quantitative determinations, such as germination rates, and presence of contaminants. The author contends that statistical analysis is indispensable for seed analysts, and takes a comprehensive look at the problems involved and how to use statistical methods to address them. From tolerance and the probability of error to noxious weed analysis, the book provides a solid theoretical and practical grounding in essential statistical methods for seed testing. 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.…

Taschenbuch. Condizione: Neu. Neuware - This book presents the findings of Guy N. Collins, a well-known plant breeder, who studied the characteristics of a new type of Indian corn from China.

Paperback. Condizione: 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.

Paperback. Condizione: New. Print on Demand. This book presents a detailed study into the inheritance of an obscure maize variation. The author begins with the discovery of a single white ear of corn in a field of yellow corn. The conditions under which the ear was found suggest a direct mutation, challenging the idea that this deviation was the result of cross-pollination. The book delves into the behavior of the white ear's progeny, looking at the inheritance of its endosperm color in its offspring. The research described in this book provides evidence to support the author's argument that segregation of traits in hybrids is often incomplete and influenced by many factors. The results of this study challenge the theory of complete segregation, which has been a cornerstone of Mendelian inheritance. This study adds to the understanding of the complexity of genetic inheritance and the variation found in nature.

Paperback. Condizione: New. Print on Demand. This book is a detailed exploration of the commercial utility of various species within the genus Atriplex, commonly known as saltbushes. Over the past century, members of this genus have gained prominence in the arid regions of the West, particularly as a class of forage plants. However, accurately identifying the various species has proven difficult due to the complex and highly variable nature of their fruits. This book aims to provide a comprehensive resource that will assist experiment station workers and seedsmen in accurately identifying species of Atriplex and their seeds. It features descriptions, illustrations, and photographs of authentic specimens of both fruits and seeds. The text also explores the ecology of the genus, including the unusual manner in which many species produce seeds. This book presents a valuable tool for understanding the saltbush genus, aiding in the selection and cultivation of these important forage plants, which have the potential to restore vitality to degraded and marginal ecosystems.

Paperback. Condizione: New. Print on Demand. This book uncovers a simple yet effective method for farmers to increase their corn yields by utilizing the increased vigor and fertility that results from hybridizing different varieties. Despite being discovered over a century ago, this practice, which involves planting two varieties together and removing the tassels from one to ensure cross-pollination, has never been widely adopted. The author presents historical evidence and recent experiments to support the assertion that first-generation hybrids consistently outperform their parent varieties and can be a valuable tool for increasing crop production. The book highlights the potential of this method, and its insights on maximizing corn yields are of great significance to farmers and agriculturalists alike.
