Summary Powdery mildew is an economically important disease caused by c . 1000 different fungal species. Erysiphe vaccinii emerging powdery species that impacting the blueberry industry. Once confined to North America, E. now spreading rapidly across major blueberry‐growing regions, including China, Morocco, Mexico, and USA, threatening millions in losses. This study documents its recent global spread analyzing both herbarium specimens, some over 150‐yr‐old, fresh samples collected...
Abstract The spatial distribution of modern varieties, and the genes they embody, has economic value because it affects crop productivity from year to year. Since farmers choose varieties based on observable traits rather than cannot see, a first step in understanding is better understand determinants varieties. In this paper, we have constructed diversity indices area distributions wheat Australia China. We hypothesise that factors explaining variation these are related farmers' demand for...
The impact of wheat diversity on the productivity in China is examined using total factor (TFP) and an instrumental variable approach. TFP seven key wheat-producing provinces shows significant, though variable, growth for all during period 1982-1995. Analysis causes tests alternative taxonomies (named varieties morphological groups) three measures diversity. analysis significant effects with results consistent across Further decomposition estimation confirms relative magnitude growth.
This study examines the impact of uncertainty in core technology R&D innovation on a second-tier supply chain comprising two rival final product manufacturers and key component supplier. It investigates single manufacturer's decision-making regarding investment outcome transformation. Four scenarios are identified based different transformation strategies: no investment, individual invest-ment with self-use outcomes, transfer, cooperative sharing. The analyzes how these strate-gies...
The continued cultivation of landraces by household farms in centers domestication and diversity is considered to be an situ means conservation crop genetic resources. However, because has into the present does not ensure that this de facto strategy for conserving resources will continue future. Whether or traditional varieties cultivated rests primarily on factors influencing decisions these farms. This paper focuses two questions: 1) what are significant determinants wheat varieties; 2)...
Spatial diversity indicators may serve an important function for policymakers as they seek to manage crop genetic and potential externalities associated with diffusion of some types genetically improved crops. This paper adapts spatial indices employed by ecologists in the study species area distributions modern wheat varieties contrasting production systems Australia China. The variation three interrelated concepts richness, abundance, evenness is explained factors related demand supply...
