Download or read book The Theory and Practice of Breeding to Type and Its Application to the Breeding of Dogs Farm Animals Cage Birds and Other Small Pets written by C. Davies and published by Read Books Ltd. This book was released on 2013-04-16 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1928, this volume contains a timeless guide to breeding animals, with a special focus on breeding to type. Type breeding refers to breeding animals in order to produce traits that define certain breeds or are particularly desirable, with such characteristics usually being the basis for animal shows and competitions. This profusely-illustrated guide deals with all manner of animals ranging from dogs to cattle, and it will be of considerable utility to anyone with an interest in the subject. Contents include: “Breeding to Type”, “False Doctrines", "Pedigree", "Modern Heredity", "Mendelism", "Establishing a Strain", "Inbreeding", "Methods of Mating", "Colour", "Heredity and Disease", "Early Maturity", "Sterility", etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on farming.

Download or read book Plant Breeding written by Neal C Stoskopf and published by CRC Press. This book was released on 2019-09-05 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to present a readable format on plant breeding principles and their application, based on the collective experience of the three authors, but with a heavy dependence on the scientific literature. Modem pedagogy recognizes that teaching can occur when students are motivated to learn. Subject matter must be communicated in an interesting, appealing, and understandable fashion. In preparing the text, every effort has been made to translate pertinent plant breeding references into a clear, logical, and comprehensible format for those studying the challenging and dynamic field of plant breeding.
Download or read book Potato Breeding Theory and Practice written by John E. Bradshaw and published by Springer Nature. This book was released on 2021-04-09 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potato (Solanum tuberosum) is the world’s fourth most important food crop after maize, rice and wheat with 377 million tonnes fresh-weight of tubers produced in 2016 from 19.2 million hectares of land, in 163 countries, giving a global average yield of 19.6 t ha-1 (http://faostat.fao.org). About 62% of production (234 million tonnes) was in Asia (191), Africa (25) and Latin America (18) as a result of steady increases in recent years, particularly in China and India. As a major food crop, the potato has an important role to play in the United Nations “2030 Agenda for Sustainable Development” which started on 1 January 2016 (http://faostat.fao.org). By 2030 the aim is to “ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year round”. By then, the world population is expected to reach 8.5 billion and continue to increase to 9.7 billion in 2050. For potatoes, the need is to increase production and improve nutritional value during a period of climate change, a key aspect of which will be the breeding of new cultivars for a wide range of target environments and consumers. The aim of the book is to help this endeavour by providing detailed information in three parts on both the theory and practice of potato breeding. Part I deals with the history of potato improvement and with potato genetics. Part II deals with breeding objectives, divided into improving yield, quality traits and resistance to the most important diseases and pests of potatoes. Part III deals with breeding methods: first, the use of landraces and wild relatives of potato in introgression breeding, base broadening and population improvement; second, breeding clonally propagated cultivars as a way to deliver potato improvement to farmers’ fields; third, as an alternative, breeding potato cultivars for propagation through true potato seed; and fourth, gene editing and genetic transformation as ways of making further improvements to already successful and widely grown cultivars. Included are marker-assisted introgression and selection of specific alleles, genomic selection of many unspecified alleles and diploid F1 hybrid breeding.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Theory and Practice of Cattle-Breeding In this little book I have endeavored to gather together such parts of my contributions to the periodical press for a number of years past as seemed to be of sufficient value for the practical breeder to justify a more permanent form. If an earnest effort to do something for my fellow-laborers in the great domain of cattle-breeding needs any justification, I may, perhaps, find it in the kind reception which my occasional writings have met with from the cattle-breeders of the country. I am grateful to them for many years of friendly appreciation, and I offer this digest of my work in the hope that it may prove of some value to them and to those who shall succeed them. I wish to take this opportunity to acknowledge the assistance my sons have given me in preparing all my work for the press. Without their aid much - even most - of it could never have been done.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Theory and Practice of Rational Breeding In 1886, after having been a breeder of basset-hounds for some fourteen years, during which time I was an exceedingly close observer of the results brought about by the crossing of individual hounds of the same family, of hounds of differing families, of hounds of differing strains, and accidental alliances of basset-hounds with other varieties of the species Dog, I produced - being firmly convinced that there was some reason for the differences in individual, family, strain, and variety types of the species, deterioration, degeneration, difficulty in rearing, and, finally, non-reproduction in the breed - a small work for the purpose of giving the reasons for the above, and for the additional purpose of showing the members of the Basset Hound Club how a better result could be obtained. This small work was brought out, or at least the principles on which it was based, by the Chasse Illustree, in three articles written by Mons. E. Frechon, who, having studied its scientific basis, says: - "It is in the formation and application of these rules that the English have become, and have remained, so far as breeding is concerned, our masters. "Whereas we in France leave everything to luck, awaiting some fortuitous and unforeseen circumstance to produce superior types in a breed, over there (England) they have for ages modified the laws which regulate crossing. They have, I might almost say, 'weighed' the exact proportion of blood necessary to be added, through several generations, to that of some celebrated individual, so as to ensure in the end his type and attributes. "Yet, notwithstanding pedigrees and the like, we, on the other hand, unfortunately for us, continue to breed, trusting to luck, the outcome being, of course, that our produce is invariably destined to be inferior, and therefore beaten by the produce of rational breeding, of breeding reduced to a system of algebraical formulae. Yes, formulae which we may laugh, but a system, nevertheless, which furnishes, nineteen out of twenty times, field prize winners, champions on the show bench, celebrities on the turf, and prize winners at the agricultural meetings." Such, then, are Mons. Frechon's views, and he has put them before his countrymen more in the manner of an Englishman than any one else.
