Dataset for: Adoption estimates of modern sweetpotato varieties in selected countries in Southeast, South Asia and East Asia. Jan 10, 2022 Gatto, Marcel; Pradel, Willy; Suarez, Victor; Qin, Junhong; Hareau, Guy, 2017, "Dataset for: Adoption estimates of modern sweetpotato varieties in selected countries in Southeast, South Asia and East Asia.", https://doi.org/10.21223/P3/AWDL2Y, International Potato Center Eight countries in Southeast Asia which are considered major sweetpotato producing areas were selected this study. This study adopts a refined expert elicitation (EE) approach. EE workshops were used as an inexpensive alternative to the collection of national representative adoption data. An average of 13 experts working in the sweetpotato value ch... This Dataset is harvested from our partners. Clicking the link will take you directly to the archival source of the data.
Dataset for: Potato seed degeneration and soil colonization driven by inoculum sources of Rhizoctonia solani Jan 10, 2022 Navarrete, Israel; Kromann, Peter; Andrade-Piedra, Jorge; Thomma, Bart; Struik, Paul, 2022, "Dataset for: Potato seed degeneration and soil colonization driven by inoculum sources of Rhizoctonia solani", https://doi.org/10.21223/P3/DRJSRL, International Potato Center Rhizoctonia solani is a saprophytic fungal pathogen causing potato seed degeneration. Unfortunately, the effects on seed degeneration and soil colonization caused by R. solani inoculum sources (black scurf on seed tubers and propagules in the soil), and inoculum densities have been poorly quantified. For this reason, we carried out a research aimin... This Dataset is harvested from our partners. Clicking the link will take you directly to the archival source of the data.
Dataset for: Modern sweetpotato varietal release information in selected countries in Southeast, South Asia and East Asia. Jan 10, 2022 Gatto, Marcel; Pradel, Willy; Suarez, Victor; Qin, Junhong; Hareau, Guy, 2017, "Dataset for: Modern sweetpotato varietal release information in selected countries in Southeast, South Asia and East Asia.", https://doi.org/10.21223/P3/XJGEG0, International Potato Center Eight countries in Southeast Asia which are considered major sweetpotato producing areas were selected this study. Sweetpotato released data from 18 countries/Provinces/States were collected. In total 602 varieties were documented (including duplicates, as each province in China has its own release system) and a total of 66 varieties have been rele...

Replication Data for: Chlorophyll concentration in leaves is an indicator of potato tuber yield in water-shortage conditions Jan 10, 2022 Ramirez, David; Yactayo, Wendy; Gutierrez, Raymundo; Mares, Victor; De Mendiburu, Felipe; Posadas, Adolfo; Quiroz, Roberto, 2022, "Replication Data for: Chlorophyll concentration in leaves is an indicator of potato tuber yield in water-shortage conditions", https://doi.org/10.21223/P3/HVKPWJ, International Potato Center The phenotyping of secondary characters is a common practice in breeding programs aiming at finding physiological mechanism related to drought tolerance. However, the dynamics of these characters depend on crop phenology, levels of water shortage, and other factors that affect their relationship with yield and limit their capacity to be used for pr...

Replication data for: Effect of partial root-zone drying irrigation timing on potato tuber yield and water use efficiency Jan 10, 2022 Yactayo, Wendy; Ramirez, David; Gutierrez, Raymundo; Mares, Victor; Posadas, Adolfo; Quiroz, Roberto, 2022, "Replication data for: Effect of partial root-zone drying irrigation timing on potato tuber yield and water use efficiency", https://doi.org/10.21223/P3/MIVGMU, International Potato Center Partial root-zone drying (PRD) is an irrigation technique which has shown increased water use efficiency (WUE) without yield reductions in potato and other crops. However, questions remain as to the effect of the water restriction initiation timing and the level of alternate water restriction on the response of the potato crop. In this study, we te...

Replication Data for: Release of orange-fleshed sweetpotato (Ipomoea batatas [l.] Lam.) cultivars in Mozambique through an accelerated breeding scheme Jan 10, 2022 Andrade, Maria; Naico, Abdul; Ricardo, Jose; Alvaro, Abilio; Makunde, Godwill; Low, Jan; Ortiz, Rodomiro; Gruneberg, Wolfgang, 2022, "Replication Data for: Release of orange-fleshed sweetpotato (Ipomoea batatas [l.] Lam.) cultivars in Mozambique through an accelerated breeding scheme", https://doi.org/10.21223/P3/OIQSOC, International Potato Center The objectives of this study were to describe an Acelerated breeding scheme, ABS, for sweetpotato and to investigate the efficiency of this breeding scheme for selecting high-yielding and well-adapted orange-fleshed sweetpotato (OFSP) cultivars with high β-carotene content. More than 198,500 seeds from two crossing blocks were germinated and rapidl... This Dataset is harvested from our partners.

Representing SSR molecular marker profiles using concepts from Andean khipus Jan 10, 2022 Simon, Reinhard; Carhuapoma, Pablo; Nuñez, Jorge; Hualla, Vilma; De Haan, Stef; Ghislain, Marc; Zorrilla, Cinthya; Gomez, Rene; De Mendiburu, Felipe; Roca, William; Bonierbale, Merideth, 2014, "Representing SSR molecular marker profiles using concepts from Andean khipus", https://doi.org/10.21223/P3/VOSMTS, International Potato Center Genebanks increasingly use molecular markers for routine characterization of ex-situ collections and farmer managed diversity. The International Potato Center presently uses a SSR marker-kit to create molecular profiles for potato accessions.
