Summary The highlights and achievements of 40 years of potato research in agronomy; genetics, breeding and varietal assessment; physiology;
pathology (including nematology); virology; engineering; and utilization are reviewed and the prospects for new developments
are analysed. In all disciplines progress has been impressive and has changed the potato industry dramatically. Yet, some
old problems remain unsolved (Phytophthora infestans, blackspot) or are returning (cyst and other nematodes) and new problems have arisen (e. g. volunteer potatoes, new strains
of PVY, virulent cold-resistant strains ofPseudomonas solanacearum). The potato industry faces new challenges from society (environmentally safe production) and the consumers (improved quality).
Farmers, researchers and processors have access to many new exciting techniques, tools and opportunities, such as precision
farming, genetic engineering, molecular detection and analytical techniques, integrated chain management, novel preservation
and processing methods. The problems and opportunities both warrant a continued effort in potato research. 相似文献

Single Nucleotide Polymorphisms (SNPs) are the most frequent form of DNA variation in the genome. SNPs are genetic markers which are bi-allelic in nature and grow at a very fast rate. Current genomic databases contain information on several million SNPs. More than 6 million SNPs have been identified and the information is publicly available through the efforts of the SNP Consortium and others data bases. The NCBI plays a major role in facillating the identification and cataloging of SNPs through creation and maintenance of the public SNP database (dbSNP) by the biomedical community worldwide and stimulate many areas of biological research including the identification of the genetic components of disease. In this review article, we are compiling the existing SNP databases, research status and their application. 相似文献

Summary After an initial phase of development and programme establishment the activities of the International Potato Center (CIP)
grew rapidly from 1981 to 1985, putting emphasis on germplasm distribution, research on diffused-light storage and TPS, and
exploration of sources of resistance. Later, strong emphasis was given to genetic resource utilization and field resistance
to late blight. The impact of CIP research showed internal rates of return ranging from 26 to 102 percent.
At the end of the 1980s CIP's financial resources were cut severely and restructuring the programme was necessary. Through
a careful process of prioritizing, programmes are identified which will contribute most to ensuring the continued increase
of potato production in developing countries and to continuing the leading role of CIP in potato research. 相似文献

Grazing legumes in Europe: a review of their status, management, benefits, research needs and future prospects 总被引：3，自引：0，他引：3

In many parts of Europe there has been a net decline in the use of forage legumes since the 1980s, despite the reputed value of legumes for low‐input livestock production systems. The political environment within which livestock farming in much of Europe operates (Common Agricultural Policy) is shifting the balance of economic advantage towards legumes and away from high usage of inorganic fertilizer. This has already been found for legume and grass–legume silages when compared with grass silages with a potential economic gain for farmers averaging 137 € ha?1, corresponding to an annual benefit for the European livestock farming sector of as much as € 1300 million. Recent literature has shown that legume‐based grazing systems have the ability to reduce environmental problems by increasing the efficiency of N use and by avoiding a high transient surplus of soil mineral N. From the perspective of livestock nutrition, when forage legumes contain moderate levels of secondary compounds, such as condensed tannins and flavonoids, they offer considerable advantages including increased efficiency of N utilization within the digestive tract, reduced incidence of bloat hazard and higher resilience to parasites. Nevertheless, these benefits are partially counterbalanced in both temperate and Mediterranean regions by difficulties in establishment, maintenance and management under grazing. To gain knowledge on mixed grass–legume pastures, further research is required on: (i) the development of sustainable systems of livestock production which can maintain sward persistence and agricultural production under environmental stress; (ii) increasing knowledge of soil–plant–animal relations for a wide range of leguminous species, and under different soil types and climatic situations; and (iii) the benefits for consumers of food produced from low‐input livestock production systems. 相似文献
