The objectives of this research were to assess the yield response of orange fleshed sweet potato to water supply at different frequencies; to evaluate how beta carotene content and nutritional water productivity of orange fleshed sweet potato will be affected by water supply at different frequencies and; to calibrate and validate the Soil Water Balance (SWB) model for orange fleshed sweet potato. A field trial was established in December 2011 at the University of Pretoria experimental Farm (Hatfield, Gauteng Province), under a rainshelter. The trial comprised of four irrigation regimes namely, Ttw (irrigated twice a week), Tow (irrigated once a week), Totw (irrigated once in two weeks) and Tdryl (rain and supplemental irrigation dependent). Tdryl, an independent field block, was established outside the rain shelter. Growth and yield analyses were carried out during the growing season. Irrigation was applied to field capacity (FC), depending on water required by each treatment, as determined with a neutron probe three times in a week.

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.

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.

The stories presented in this report illustrate how improved collaboration among RTB centers is making a real difference. This includes harnessing the potential of genomics to accelerate the development of improved RTB varieties, facilitating collaborative responses to critical crop diseases and improving postharvest options. During its second year, the CGIAR Research Program on Roots, Tubers and Bananas (RTB) expanded its geographic reach and its network of partners while launching a series of collaborative initiatives aimed at resolving the most serious constraints faced by smallholder farmers growing RTB crops. While this work was initiated within a framework of seven disciplinary themes, RTB started a process to transition from an output-focused research agenda to one based on outcomes and impacts.

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.

The sweet potato is at present grown in more than 100 of the independent countries of the world. Most of the producer nations are situated in the tropical developing world where a high proportion of the poorest people live. Increasing recognition of the potential which sweet potato holds for combating food shortages and malnutrition has resulted in intensified research efforts to enhance production and consumption. This book reviews our knowledge about the varied aspects of the sweet potato as a human food and animal feedstuff. This volume will be found practical and informative by all those involved in food and nutrition sciences, especially but not exclusively in developing countries. These include research workers in food or agriculture, dieticians, nutritionists, food technologists, students, planners and policy makers.
