The 'Ceratitis FAR complex' is a species complex of African fruit flies (Diptera, Tephritidae) including the major agricultural pest Ceratitis rosa and the morphologically similar Ceratitis fasciventris and Ceratitis anonae. To resolve their intra- and interspecific genetic relationships and to estimate gene flow within this complex, we surveyed allelic variation at 16 microsatellite loci in 27...

This article studies the synergy effect of entrepreneurship on China’s industrial clusters. We propose an extension to Duranton and Overman’s (2005) method which enables us to delimit industrial clusters in space. The empirical model is identified with historical measures of local entrepreneur potential in the spirit of Chinitz (1961). We find that measures of entrepreneurship contribute signif...

the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

This article explores the theoretical issues of creating clusters, their tasks and capabilities, impact clusters on regional competitiveness. The internationally standardized experience in creation development agricultural were learned deeply this article. directions Uzbekistan are indicated.

Abstract The article discusses the issues and a number of technical recommendations for effective use existing agricultural reclamation equipment available in clusters republic, as well prospects their development large-scale implementation technological processes those problems that may arise during operation ways to eliminate them production conditions. A irreplaceable are given modernization...

In this study, multivariate statistical methods including factor, principal component and cluster analysis were applied to surface water quality data sets obtained from the Tahtali River Basin, Turkey. Factor and principal components analysis results revealed that surface water quality was mainly controlled by agricultural uses and domestic discharges. Cluster analysis generated two clusters. B...
