This book was released on 2021 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Colorado potato beetle (Leptinotarsa decemlineata) is the most widespread and destructive insect defoliator pest of potato and its control has historically been achieved through the use of insecticide. The diploid potato species Solanum chacoense has been utilized for over four decades in an attempt to introgress glycoalkaloid-based insect resistance into cultivated tetraploid potato. Despite these efforts, insect resistant cultivars have not been achieved, due in part to the complex genetics underlying the trait. The creation of inbred diploid lines would allow more efficient examination and deployment of this economically important trait. We introduced self-compatibility into diploid insect resistant S. chacoense germplasm and developed the first potato recombinant inbred line (RIL) population to study, understand and deploy this mechanism of host-plant insect resistance in cultivated, diploid breeding lines.We first examined the genetic features underlying leptine glycoalkaloid mediated Colorado potato beetle host plant resistance in the F2 generation derived from a cross between S. chacoense lines USDA8380-1 (80-1) and M6. Using biparental linkage mapping, a major overlapping QTL region with dominant effects was identified on chromosome 2 explaining 49.3% and 34.1% of the variance in Colorado potato beetle field resistance and leptine accumulation, respectively. Bulk segregant whole genome sequencing of the same F2 population detected QTL associated with Colorado potato beetle resistance on chromosomes 2, 4, 6, 7, and 12. Candidate genes within these QTL regions were identified by weighted gene co-expression network analysis of parental lines and resistant and susceptible F2 individuals.Second, we exploited M6-mediated self-compatibility and established vigorous, F5 inbred diploid lines to further examine loci associated with Colorado potato beetle resistance and explore the practicality of inbreeding in diploid potato. F5 inbred lines carrying Colorado potato beetle resistance equivalent to the resistant donor parent were created without field selection during the inbreeding process. We report that the ratio of acetylated to non-acetylated glycoalkaloids measured under greenhouse conditions is a powerful metabolite marker to predict field performance without incurring the costs of conducting a Colorado potato beetle field trial. Leptine production was successfully introduced into diploid breeding germplasm. Single nucleotide polymorphism (SNP) genotyping coupled with stylar analysis of pollen tube growth and self-fertility phenotyping of the F4 and F5 generations revealed that multiple factors mediate the self-compatible response in this RIL population.Third, we assessed the initial transcriptional and metabolite response to Colorado potato beetle herbivory in beetle resistant and beetle susceptible S. chacoense lines over a 48-hour time course. To facilitate genome editing modification of the leptine biosynthesis pathway, we characterized the allelic variation between S. chacoense 80-1 and M6 in a candidate leptine biosynthesis gene identified by transcriptional profiling.This work highlights the challenges of establishing inbred germplasm, reinforces the complexity of selecting for self-fertility in diploid potato, and lays the foundation for optimization of potato RIL development. The availability of highly homozygous Colorado potato beetle resistant lines will enable further genomic inquiry of the loci contributing to this trait and will facilitate rapid deployment of beetle resistant diploid potato varieties.

Book excerpt: 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.
Download or read book Integration of Insect Resistant Genetically Modified Crops within IPM Programs written by Jörg Romeis and published by Springer Science & Business Media. This book was released on 2008-07-01 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect pests remain one of the main constraints to food and fiber production worldwide despite farmers deploying a range of techniques to protect their crops. Modern pest control is guided by the principles of integrated pest management (IPM) with pest resistant germplasm being an important part of the foundation. Since 1996, when the first genetically modified (GM) insect-resistant maize variety was commercialized in the USA, the area planted to insect-resistant GM varieties has grown dramatically, representing the fastest adoption rate of any agricultural technology in human history. The goal of our book is to provide an overview on the role insect-resistant GM plants play in different crop systems worldwide. We hope that the book will contribute to a more rational debate about the role GM crops can play in IPM for food and fiber production.

Download or read book Solanum tuberosum written by Mustafa Yildiz and published by BoD – Books on Demand. This book was released on 2021-12-22 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato (Solanum tuberosum L.) is the fourth-largest food crop produced in the world with approximately 370 million tonnes. This product is a staple in many diets throughout the world and the underground swollen tubers of the plant are rich sources of proteins, carbohydrates, minerals (K, Mn, Mg, Fe, Cu and P), and vitamins (C, B1, B3, B6, K, folate, pantothenic acid). Improvement of new potato cultivars resistant to biotic and abiotic factors is extremely important, as these are the main reasons for decreased potato production. Seed tuber production and tuber storage under healthy conditions after harvest are two important issues in potato cultivation. As such, this book discusses the importance of the potato plant and examines ways to increase its production and develop new cultivars resistant to stress factors via conventional and biotechnological methods.
Download or read book Broadening the Genetic Base of Crop Production written by H. David Cooper and published by . This book was released on 2001 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the previously neglected interface between the conservation of plant genetic resources and their utilization. Only through utilization can the potential value of conserved genetic resources be realized. However, as this book shows, much conserved germplasm has to be subjected to long-term pre-breeding and genetic enhancement before it can be used in plant breeding programs.The authors explore the rationale and approaches for such pre-breeding efforts as the basis for broadening the genetic bases of crop production. Examples from a range of major food crops are presented and issues analyzed by leading authorities from around the world.
Download or read book Root and Tuber Crops written by J.E. Bradshaw and published by Springer Science & Business Media. This book was released on 2010-09-11 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is important to include Tuber and Root Crops in the Handbook of Plant Breeding. They include starchy staple crops that are of increasing importance for global food security and relief of poverty, important millennium goals for the United Nations. Indeed, 2008 was the UN International Year of the Potato in recognition of this role of the potato as the world’s third most important food crop after wheat and rice. The other major staples are cassava, sweetpotato and yam. Together they occupy about 50 million hectares, with production at 640 million metric tons, of which 70% is in developing countries. In total there are more than 30 species of Root and Tuber Crops grown in the world today. Given the content of other volumes in the series, it makes sense to include sugar and fodder beets; swedes and turnips; and minor root and tuber crops so that the book series is as complete as possible. Like the other volumes in the series, this one will present information on the latest in applied plant breeding using the current advances in the field, from an efficient use of genetic resources to the impact of biotechnology in plant breeding. Seven crop specific chapters are proposed, together with an introduction to this diverse set of plant species. Outstanding scientists for each crop species are proposed as senior authors, who may invite co-authors to contribute part of a chapter. In order to increase the overall acceptance of the volume, balance will be sought with authors from different research groups/countries who will be asked to contribute and collaborate where appropriate. The book should be of interest to researchers in both academic and industrial settings, and in both developed and developing countries, as well as students and teachers of plant breeding. It is currently extremely important to educate and train a new generation of plant breeders given the challenges faced by humankind in producing more food for an expanding global population during a period of environmental (including climate) change.
