Download or read book Potato Production Worldwide written by Mehmet Emin Calıskan and published by Academic Press. This book was released on 2022-10-22 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato is a crop grown on all inhabited continents of the globe. It is included in the top five crops of the world, used as staple food in several countries, and the number of people daily consuming the potato may surpass one billion. Despite the high quantities of seed potato produced worldwide, there are yield gaps due to challenges such as abiotic stresses, pests, climate change and poor production practices. A region-wide critical analysis of yield declining factors can help formulate management strategies that can improve potato yields. Bridging yield gaps in potato will ultimately ensure the role of this crop in securing current and future food security. Potato Production Worldwide presents information on this global crop from its history, morphology, and taxonomy to the growth and development of the potato crop, including the latest strategies in addressing today’s biotic and abiotic challenges. This book identifies the reasons for yield gaps in various potato production regions of the world, as well as presenting the best production practices, pest management strategies and approaches to deal with climate change from the perspective of potato production. Chapters provide important insights into potato production cultures and approaches in the major potato production countries. Potato Production Worldwide will be a valuable resource for researchers, scientists and students seeking a comprehensive view of successful potato production. Provides comprehensive information on the origin, history, taxonomy, morphology, ecophysiology, growth and development of the potato Addresses production practices, including irrigation, nutrient management, harvesting and post-harvest techniques Explores the impact of Abiotic stresses (drought, chilling, salinity etc.) and their management

Download or read book Redesigning Diploid Potato Breeding with Self compatibility written by Maher Alsahlany and published by . This book was released on 2019 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of cultivated potato varieties (Solanum tuberosum Grp. Tuberosum 2n=4x=48) are tetraploid. For over a 100 years yield increases have been obtained from improvements in production management rather than through genetic improvement. The goal of this study is to develop diploid germplasm that is self-compatible (SC) that can be used as parental material F1 hybrid variety breeding scheme. Producing true F1 hybrid potato seeds requires first developing SC inbred lines. Wild and cultivated species and dihaploid produced from cultivated tetraploid potato are self-incompatible (SI). We designed our study to develop breeding strategies to generate two germplasm pools using the benefit of having the S-locus inhibitor (Sli) gene from Solanum chacoense (M6).The first goal was to create a SC diploid potato multi-species germplasm pool. The objectives of recurrent selection (RS) are to introgress and improve SC in a multi-species potato germplasm pool that has essential cultivated tuber and canopy traits. SC was increased from 16% to 85% in the progeny over five cycles of RS. Genetic variability analysis based on 4885 single nucleotide polymorphisms (SNPs) was maintained in the germplasm based on heterozygosity, and Neighbor-joining tree (NJ), Principal component analysis (PCA), and Structure analyze. Agronomic trait measurements showed that the RS population has genetic variability for many agronomic traits such as tuber appearance, tuber shape, and average tuber weight, average tuber yield, and tuber specific gravity. SC combined with essential tuber traits, is a valuable germplasm resource for inbred/F1 hybrid variety development.The second goal was to introgress self-compatibility into S. tuberosum dihaploids by crossing SC donor lines to cultivated dihaploids (2n=2x=24) produced from cultivated lines with traits such as chip processing, disease resistance, and virus resistance. A set of three crosses with dihaploid selections was used to select against undesirable traits and reduce the genetic contribution of the SC donor parents. The SC progeny were used in each round of crosses to a set of cultivated dihaploids. This set of three crosses is referred to as S. tuberosum backcross. Genetic diversity analysis based on over 6000 SNPs and agronomic traits measurements showed that the backcross (BC) population has genetic variability for many agronomic traits such as tuber appearance, tuber shape, and average tuber weight, average tuber yield, and specific gravity. The SC germplasm is a valuable resource for the future development of dihaploid F1 hybrid varieties.Third, a study was conducted to examine the results of chloroplast counting in stomatal guard cells, SNP genotyping calling, and flow cytometry to determine ploidy level. All three methods of ploidy determination agreed for evaluating ploidy. Twenty-eight clones with known ploidy level were used as reference samples (14 diploid lines (2n=2x=24), 14 tetraploid varieties and advanced breeding lines (2n=4x=48)) and 102 samples of unknown ploidy level from the RS and the BC populations. These results demonstrate the usefulness of chloroplast counting as an efficient and inexpensive method for breeders to differentiate ploidy between diploid and tetraploid potato.SNP-based heterozygosity, an unweighted pair-group method with arithmetic averages (UGPMA), PCA, and Structure analysis were done using the RS and BC germplasm pools. The NJ tree and PC analysis show the BC2 selections are distinct from the cycle 4 RS selections. The BC2 selections were clustered in one distinct group, and genetic variability was maintained within the group. Developing SC multi-species germplasm pool by using recurrent selection and SC S. tuberosum pool using backcross has led to two germplasm pools that could be tested to identify heterotic combinations. These two germplasm pools may help us develop F1 hybrid diploid potato varieties in the future.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "Potato (Solanum tuberosum L.) originated in the South American Andes and is an economically important staple crop that can be successfully grown in various conditions and altitudes. The potato genome is complex, with a large gene pool drawn from numerous wild species of varying ploidy levels ranging from diploids to hexaploids. Potato breeding efforts in North America and Europe have traditionally focused on vegetative propagation of tetraploid potato because of its higher yield. However, due to the high heterozygosity levels and difficulties of tetraploid breeding, new improvement efforts are increasingly looking to diploid species as a means of introgressing traits into crop varieties.Genome sequence data and means of analyzing and visualizing the data, are crucial to achieve this goal. Significant work has previously been done by sequencing and publishing different potato reference genomes, a double monoploid (S. tuberosum Group Phureja - DM), two wild reference genomes (S. commersonii and S. chacoense clone M6), a landrace genome (S. stenotomum subsp. goniocalyx), and two diploid S. tuberosum genomes (Solanum tuberosum group Tuberosum RH89-039-16, Solanum tuberosum, Solyntus).The present study focuses on expanding the genomic resources for potato genome analyses. First, this study presents a newly sequenced and assembled diploid genome of S. bukasovii, which is thought to be one of the wild species that is most closely related to the cultivated potato. This genome sequence is compared with the available potato reference genomes and the results show that Copy Number Variation (CNV) affect genes have important functions such as disease resistance and metabolite biosynthesis. Second, a web portal - the Potato Genome Diversity Portal (PGDP) - was developed and implemented to visualize the published potato genomes using JBrowse and to provide a tool to investigate the genome alignments along with aiding the structural variation analysis PGDP also enables researchers to conduct research and share data"--
