“…Furthermore, the presence of nine private alleles (10.3%) and a series of 31 alleles (58.6%) with low frequency (≤10%) can be considered as a genetic reservoir for yellow passion fruit genotype selection, characterization and conservation processes for breeding programs. Likewise, this genetic reservoir of low frequency alleles could be a survival and adaptability mechanism to changing environmental conditions in natural surroundings where yellow passion fruit is cultivated, as the pathogen agent pressure or the climatic variability that is affecting world agriculture (Vermeulen et al, 2012). Additionally, an allelic richness parameter is a measure of genetic diversity that is commonly used in studies based on molecular markers that aim at selecting populations for conservation (Leberg 2002;van Zonneveld et al, 2102).…”

Colombia is one of the leading producers of yellow passion fruit but the genetic studies based on molecular markers from commercial plantations have not been considered to select interesting market material. The goal of this study was to assess the genetic variability and the population structure of 51 Colombian commercial yellow passion fruit accessions (102 individuals), and to provide the necessary information for prospective selection and breeding programs. Thus, a total of six microsatellites were amplified with 58 alleles identified and an average of 9.66 alleles per locus, including nine private and 31 rare. Diversity indexes showed polymorphic information content values of 0.74 (PIC), an observed (Ho) and expected (He) heterozygosity average of 0.52 and 0.78, respectively. Spatial distribution showed the greatest allelic richness (11 to 14) in most of the Valle del Cauca accessions. The average genetic distance among accessions was 0.68, and the cluster analysis showed three main groups poorly supported (bootstrap <50%), with slight geographical structure and high differentiation between individuals of the same accession. Structure analysis indicated K=4 as the genetic structure's uppermost hierarchical level, while Bayesian clustering showed a division of individuals into four genetically distinct groups. The low geographic structure and high variability of the accessions could be explained by allogamy and seed exchange frequency among farmers. Results issued suggest a complementary agro-morphological assessment to establish total genetic variability and implement a breeding program through assisted selection of superior genotypes in search of more productive and resistant cultivars to phytosanitary problems.

Shaping global agendas on climate risk management and climate services: an IRI perspective

2014

View full text Add to dashboard Cite

This paper provides a historical overview of the development and mainstreaming of global agendas on climate risk management and climate services from the vantage point of the International Research Institute for Climate and Society (IRI), and present two examples that illustrate how efforts to mainstream these agendas shaped both the institute and the broader communities that it sought to engage. In the first example, we trace developments that led to the emergence of a global agenda on climate services, including creation of the Climate Services Partnership (CSP). The CSP is an informal, open network of interested climate information users, providers, donors and researchers, serves as a platform for knowledge sharing and collaboration to advance climate service capabilities worldwide. The second example is mainstreaming climate risk management within the international agricultural research-for-development community. The CGIAR research program on Climate Change, Agriculture and Food Security (CCAFS) was structured to include a research theme on "Adaptation through Managing Climate Risk," which put climate risk management on the same footing within the agenda as adaptation to future climate change. We conclude with several lessons drawn from IRI's involvement in the processes that shaped global agendas around climate risk management and climate services.
