ABSTRACT:Genomic regions infl uencing resistance to powdery mildew [Blumeria graminis (DC.) E.O.Speer f. sp. hordei Ém. Marchal] were detected in a doubled haploid (DH) barley (Hordeum vulgare L.) population derived from a cross between the breeding line ND24260 and cultivar Flagship when evaluated across four fi eld environments in Australia and Uruguay. Signifi cant quantitative trait loci (QTL) for resistance to B. graminis were detected on six of the seven chromosomes (1H,
2H, 3H, 4H, 5H, and 7H). A QTL with large effect donated by ND24260 mapped to the short arm of chromosome 1H (1HS) conferring near immunity to B. graminis in Australia but was ineffective in Uruguay. Three QTL donated by Flagship contributed partial resistance to B. graminis and were detected in at least two environments. These QTL were mapped to chromosomes 3H, 4H,and 5H (5HS) accounting for up to 18.6, 3.4, and 8.8% phenotypic variation, respectively. The 5HS
QTL contributed partial resistance to B. graminis in all fi eld environments in both Australia and Uruguay and aligned with the genomic region of Rph20, a gene conferring adult plant resistance (APR) to leaf rust (Puccinia hordei Otth), which is found in some cultivars having ?Vada? or ?Emir? in their parentage. Selection for favorable marker haplotypes within the 3H, 4H, and 5H QTL regions can be performed even in the presence of single (major) gene resistance. Pyramiding such QTL
may provide an effective and potentially durable form of resistance to B. graminis. MenosABSTRACT:Genomic regions infl uencing resistance to powdery mildew [Blumeria graminis (DC.)

ABSTRACT.- Increasingly challenged by climate variability and change, many of the world's governments have turned to climate services as a means to improve decision making and mitigate climate-related risk. While there have been some efforts to evaluate the economic impact of climate services, little is known about the contexts in which investments in climate services have taken place. An understanding of the factors that enable climate service investment is important for the development of climate services at local, national and international levels. This paper addresses this gap by investigating the context in which Uruguay's Ministry of Livestock, Agriculture and Fisheries invested in and developed its National System of Agriculture Information (SNIA), a national-level climate service for the agriculture sector. Using qualitative research methods, the paper uses key documents and 43 interviews to identify six factors that have shaped the decision to invest in the SNIA: (1) Uruguay's focus on sustainable agricultural intensification; (2) previous work on climate change adaptation; (3) the modernization of the meteorological service; (4) the country's open data policy; (5) the government's decision to focus the SNIA on near-term (e.g., seasonal) rather than long-term climate risk; and (6) the participation of key individuals. While the context in which these enablers emerged is unique to Uruguay, it is likely that some factors are generalizable to other countries. Social science research needed to confirm the wider applicability of innovation systems, groundwork, data access and champion is discussed.
