Speed Breeding Systems For Food


Book Description

Speed breeding systems for sustainable food production offer a promising solution to address food security and environmental sustainability. Speed breeding technologies allow accelerating generation of new plant varieties with desired traits in a short period. These systems include genetic selection, vertical hydroponics and data-driven smart sensor applications. Quick generation of plant varieties is achieved by manipulating photoperiods of a native plant with extended light periods in a controlled environment to fasten the crop cycle. This allows for multiple plant generations to be grown and harvested in a single year rather than the typical one to two generations in traditional field-based breeding. The application of molecular markers in the analysis of crop genomes enables the identification and characterization of genetic variation within a crop species. This, in turn, helps breeders in identifying and selecting plants with desirable traits, such as resistance to pests or diseases, or improved yield. Marker-assisted selection (MAS) and genomic selection (GS) are two recent methods that revolutionized plant breeding to improve the efficiency and accuracy of selecting desirable traits. MAS allows breeders to identify desirable traits earlier in the breeding process, without having to wait for the traits to be phenotypically expressed. On the other hand, GS allows breeders to predict the performance of a plant before it is even grown and can help speed up the breeding process by allowing breeders to select plants with desirable traits much earlier in the breeding process.




Accelerated Plant Breeding, Volume 1


Book Description

Plant improvement has shifted its focus from yield, quality and disease resistance to factors that will enhance commerical export, such as early maturity, shelf life and better processing quality. Conventional plant breeding methods aiming at the improvement of a self-pollinating crop, such as wheat, usually take 10-12 years to develop and release of the new variety. During the past 10 years, significant advances have been made and accelerated methods have been developed for precision breeding and early release of crop varieties. This work summarizes concepts dealing with germplasm enhancement and development of improved varieties based on innovative methodologies that include doubled haploidy, marker assisted selection, marker assisted background selection, genetic mapping, genomic selection, high-throughput genotyping, high-throughput phenotyping, mutation breeding, reverse breeding, transgenic breeding, shuttle breeding, speed breeding, low cost high-throughput field phenotyping, etc. It is an important reference with special focus on accelerated development of improved crop varieties.

The Potato Crop


Book Description

This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

Breeding Field Crops


Book Description

While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa ration, particular attention has been given to advances in plant-breeding theo ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un changed. These objectives are (1) to review essential features of plant re production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant breeding objectives with emphasis on the importance of proper choice of objec tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.
