The objective of the paper was to illustrate using and usefulness of a joint AMMI and cluster analyses to assess the grain yield adaptive response of Polish and foreign 31 winter wheat cultivars in a range of 20 environments (locations) and across 3 years (2005-2007) under integrated crop management, using data obtained in the post-registration variety testing trials (called PDO trials), to ide...
The aim of this study was to investigate the importance of some physiological and biochemical properties related to cold adaptation mechanisms.We aimed to adopt properand efficient indices for identification of winter cold tolerance and susceptibilityin two strawberry cultivars. Differentphysiological and biochemical traits were studied under different cold treatments on the leaf and crown tiss...
Abstract Climate change poses a fundamental threat to agriculture within the Nile basin due magnitude of projected impacts and low adaptive capacity. So far, climate on for have mostly been assessed single-cropping systems, which may bias results considering that is dominated by different cropping with about one-third crop area under double cropping. In this study, we simulate single- double-cr...
Sustainably managing plant resistance to epidemic pathogens implies controlling the genetic and demographic changes in pathogen populations faced with resistant hosts. Resistance management thus depends upon the dynamics of local adaptation, mainly driven by the balance between selection and gene flow. This dynamics is best investigated with populations from locally dominant hosts in islands wi...
Plant variety and cultivar identification is one of the most important aspects in agricultural systems. The large number of varieties or landraces among crop plants has made it difficult to identify and characterize varieties solely on the basis of morphological characters because they are non stable and originate due to environmental and climatic conditions, and therefore phenotypic plasticity...
A crop can be represented as a biotechnical system in which components are either chosen (cultivar, management) or given (soil, climate) and whose combination generates highly variable stress patterns and yield responses. Here, we used modeling and simulation to predict the crop phenotypic plasticity resulting from the interaction of plant traits (G), climatic variability (E) and management act...
