Book Description
Sweet potato (Ipomoea batatas Lam.) is the seventh most important food crop among the root and tuber crops grown in the world which is widely cultivated in tropic, sub tropic and warmer temperate regions. A wide variation exists among sweet potato varieties. The molecular markers Is an important genetic diversity analysis tool for enhancing duplicates identification. The samples were collected based on an elaborative iterative survey as well as traditional knowledge from local people. Thirteen different varieties Ipomoea batatas Lam. varieties (Kuravanpady 1, Kuravanpady 2, Jellipara 1, Jellipara 2, Kottathara, Kadanadu, Kanaka, Aruna, Kanjagad, Cherukizhangu 1, Cherukizhangu 2, Thodupuzha. Palakkad) were used for morphological characterization. Morphological data were collected 60 days after planting based on the descriptors for sweet potato (IBPGR, 1991) in all the 13 samples. The variable scored were twining, plant type, ground cover, vine inter node, vine pigmentation, vine tip pubescence, mature leaf shape, mature leaf size, abaxial leaf vein pigmentation, foliage colour, petiole length, petiole pigmentation, storage root and skin colour. Molecular characterization could be more effectively used in screening varieties among sweet potatoes if coupled with other molecular markers especially ISSR, matK and rbcL markers.

Book Description
The sweet potato is considered as an excellent source of Œ≤-carotene and anthocyanins and has a considerable value in the functional food market. In this report, 21 sweet potato (Ipomoea batatas [L.] Lam) germplasms were evaluated for genetic diversity using morphological and biochemical and molecular markers. Ten morphological traits were studied, and the mean squares due to germplasm were highly significant for storage root number per plant, individual root weight, storage root (fresh) per plant, storage root (dry) per plant, storage root yield, and storage root length. UPGMA cluster analysis based on morphological traits separated the germplasm into three groups. The similarity coefficient ranged from 0.00 to 0.50 with an average of 0.176. Biochemical analysis, viz. total phenol and antioxidant, was performed to find out superior genotype at biochemical level under given conditions. Maximum total phenol was observed in the genotype ,ÄúV-12,Äù (1.39¬†mg), whereas maximum total antioxidant was observed in ,ÄúSamrat,Äù (0.30¬†mg). RAPD analysis was carried out, and out of 15 RAPD primers, 10 primers produced 96 reproducible and polymorphic bands. UPGMA cluster analysis based on RAPD data also separated the genotypes into three clusters. The results of the present study can be used for sweet potato crop improvement through molecular breeding and marker-assisted selection for desired traits in future.

Book Description
Roots and tubers are considered as the most important food crops after cereals and contribute significantly to sustainable development, income generation and food security especially in the tropical regions. The perishable nature of roots and tubers demands appropriate storage conditions at different stages starting from farmers to its final consumers. Because of their highly perishable nature, search for efficient and better methods of preservation/processing have been continuing alongside the developments in different arena. This book covers the processing and technological aspects of root and tuber foods, detailing the production and processing of roots and tubers such as taro, cassava, sweet potato, yam and elephant foot yam. Featuring chapters on anatomy, taxonomy and physiology, molecular and biochemical characterization, GAP, GMP, HACCP, Storage techniques, as well as the latest technological interventions in Taro, Cassava, Sweet potato, yam and Elephant foot Yam.

Book Description
In the last four decades of the twentieth century the use of sweetpotato was diversified beyond their classification as subsistence, food security, and famine-relief crop. In developing countries they serve both as human food and for feeding livestock. In Western countries they appeal to health conscious consumers because of their nutritional aspects. The sweetpotato is very high in nutritive value, and merits wider use on this account alone. The book has 2 parts. A general one giving up-to-date information on the history, botany, cultivars, genetic engineering, propagation, diseases and pests, nutritional data and marketing; and a second part presenting data on sweetpotato growing practices in different areas of the world. The information should be useful to researchers, practitioners and crop administrators in different countries.

Book Description
This book is a compilation of information on insect/mite/vertebrate pests and fungal/bacterial/viral/mycoplasma/nematode diseases of tropical root and tuber crops such as cassava, sweet potato, yams, taro, Amorphophallus, yam bean and tannia. The book highlights the distribution, symptoms and damage, biology, survival and spread of each pest and describes management methods. It also sheds light on different eco-friendly pest management strategies including physical, cultural, chemical, biological, host resistance and integrated methods. The book is written in a lucid style using easy-to-understand language and offers adoptable recommendations involving eco-friendly control measures. It serves as a useful reference source for policy makers, research and extension workers, practicing farmers and students. The material can also be used for teaching post graduate courses in state agricultural universities.

Book Description
Sweetpotato and potato are expanding faster than any other food crops in sub-Saharan Africa. There is growing investment in research to address bottlenecks in value chains concerning these two crops, and growing interest from the private sector in investing in them. This book addresses five major themes on sweetpotato and potato: policies for germplasm exchange, food security and trade in Africa; seed systems; breeding and disease management; post-harvest management, processing technologies and marketing systems; nutritional value and changing behaviours.

Book Description
Plant genetic resources provide a basis for food security, livelihood support and economic development as a major component of biodiversity. The Second Report on the State of the World’s Plant Genetic Resources for Food and Agriculture demonstrates the central role plant genetic diversity continues to play in shaping agriculture growth in the face of climate change and other environmental challenges. It is based on information gathered from Country Reports, regional syntheses, thematic studie s and scientific literature, documenting the major achievements made in this sector during the past decade and identifying the critical gaps and needs that should urgently be addressed. The Report provides the decision-makers with a technical basis for updating the Global Plan of Action on Conservation and Sustainable Use of Plant Genetic Resources for Food and Agriculture. It also aims to attract the attention of the global community to set priorities for the effective management of plant genet ic resources for the future. Purchase a print copy.
