Complete sequence and variability of a new subgroup B nepovirus infecting potato in central Peru
International Potato Center (CIP)
https://hdl.handle.net/10568/77836
Abstract
The complete bipartite genome (RNA1 and RNA2) of a new nepovirus infecting potato was obtained using small RNA sequencing and assembly complemented by Sanger sequencing. Each RNA encodes a single polyprotein, flanked by 5’ and 3’ untranslate regions (UTR) and followed by a poly (A) tail. The putative polyproteins encoded by RNA1 and RNA2 had…

The Nutritional Contribution of Potato Varietal Diversity in Andean Food Systems: a Case Study
International Potato Center (CIP)
https://hdl.handle.net/10568/99310
Abstract
Potato is the backbone of agriculture and diets in high-altitude food systems of Peru, where farmers grow diverse varietal portfolios. Here we report on the role of diverse landraces and modern potato varieties in the Andean diet. The dry matter, energy, protein, iron and zinc content of 12 floury and 9 bitter landraces was determined. The…

Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya?s Central Highlands
World Agroforestry Centre (ICRAF)
Abstract
Drier parts of Kenyaâ??s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding spatial-temporal variability of climatic indices such as rainfall at seasonal level is critical for optimal rain-fed…

Spatial Variation in Tree Density and Estimated Aboveground Carbon Stocks in Southern Africa
World Agroforestry Centre (ICRAF)
Abstract
Variability in woody plant species, vegetation assemblages and anthropogenic activities derails the efforts to have common approaches for estimating biomass and carbon stocks in Africa. In order to suggest management options, it is important to understand the vegetation dynamics and the major drivers governing the observed conditions. This study uses data from 29 sentinel landscapes (4640 plots)…

Abstract
Bean (Phaseolus vulgaris L.) production is challenged by many limitations with drought being among the top causes of crop failure worldwide. In this study, we constructed three small‐red‐seeded bean recombinant inbred line (RIL) mapping populations (S48M, S94M, and S95M) with a common parent (‘Merlot’) and…

Present situation and future potential of cassava in Indonesia
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/82423
Abstract
Cassava (Manihot esculenta Crantz.) in Indonesia can be considered as a controversial crop. This crop has a tremendous yield potential of almost 100 t of fresh roots/ha, but official data show that its actual productivity is only 10-20% of its biological potential. It is considered to have multiple end uses, such as food, feed, raw material for industry and…

Present situation and future potential of cassava in China
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/82425
Abstract
In China, cassava is planted mainly in the southern provinces of Guangxi, Guangdong, Hainan and Yunnan. The annual total area and production is about 400,000 ha and 6,000,000 tonnes of fresh roots, respectively. Guangxi is the main cassava producing province with more than 60% of both cassava growing area and production. Following the success of research on…
