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 Potato Virus X written by Jody Jellison Goodell and published by . This book was released on 1979 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preliminary studies were run to determine the sensitivity and reliability of enzyme-linked immunosorbent assay (ELISA) for the detection of potato virus X (PVX). ELISA was found to be capable of detecting PVX in tobacco at a 1:3333 sample dilution. The reliability of ELISA for the detection of PVX in potato was found to be comparable with that obtained by Gomphrena globosa bioassay and far superior to that obtained by greenhouse symptomatology of potato plants. ELISA was used in a large-scale survey of PVX to determine what role, if any, PVX had on the early death of potato vines, a yieldlimiting symptom-complex associated with the presence of Verticillium dahliae. Presence of PVX is correlated with increased severity of V. dahliae infection in variety 'Russet Burbank'. The probability of random occurrence (a) of this correlation was .001. The effect of PVX on V. dahliae colonization was most pronounced in fields where early dying was most severe and the effect of PVX, on V. dahliae colonization appeared to be seed-source dependent. Results suggest that the use of virus-free seed may be a useful cultural practice for reducing the level of early dying of potato vines. An inverse relationship was observed between PVX infection and the incidence and severity of Colletotrichum atramentarium infection, (a = .001), possibly due to an effect of the virus on plant nutritional levels.

Further, a new section discusses theoretical foundations of potato pest management and includes chapters on ecological theory, evolutionary theory, and a case study on their applications to elucidate differences between Eastern and Western populations of Colorado potato beetle in North America. There is also a new chapter on the foundations of integrated pest management and their applications in controlling insect pests. The sections on the biology of main pests and on control methods now feature the latest information, including emphasis on recent advances in molecular biology and genomics. Information on the use of dsRNA technology for pest control is also included, as are new chapters on potato ladybirds and on hemipterous pests other than aphids and psyllids. This second edition provides improved integration and logical connections among chapters and expanded geographic scope of coverage making it the ideal reference on the topic. Fully revised and updated with new sections on potato-growing regions and theoretical foundations of potato pest management using ecological theory, evolutionary theory and relevant case study insights Contains improved integration and logical connections among chapters, expanded geographic scope of coverage, and scientific advances Emphasizes recent advances in molecular biology and genomics, including the use of dsRNA technology for pest control

Download or read book The Potato Crop written by P.M. Harris and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 927 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research and publications on the potato crop have burgeoned since the first edition of this book was published in 1978. However, the warm reception of the first edition suggested that it had a useful part to play in promoting the scientific basis for understanding and improving the yield and quality of the crop. Since the first edition was out of print and a second reprint would not have taken into account the contributions made by research over the intervening years, it became obvious that a complete revision was necessary. There was, in particular, a need to take account of the rapid extension of interest in the crop into climates and farming systems with which it has not been traditionally associa,ted. Those involved with the crop will be sadly aware that a number of contributors to the first edition are no longer with us. Their contribution to our knowledge of the crop will however be a permanent legacy of their achievement. I would like to thank all those who have contributed to the book for their willingness to cooperate in the difficult task of bringing their particular subject up to date. This is even more noteworthy for the pressure of time appears to be almost an order of magnitude higher than it was when the first edition was tackled.
