[email protected] Zusammenfassung Qualitätssicherung nimmt in der Agilen SoftwareEntwicklung auf den ersten Blick keine große Rolle ein. Dennoch ist Qualität ein grundlegendes Prinzip von Agilen Entwicklungsmethoden, das implizit von vielen Agilen Praktiken umgesetzt wird. Dieser Beitrag stellt die Grundlagen Agiler Software-Entwicklung dar und gibt einen Überblick über zentrale Agile Praktik...

It has been argued that by truncating the sample space of the negative binomial and of the inverse Gaussian-Poisson mixture models at zero, one is allowed to extend the parameter space of the model. Here that is proved to be the case for the more general three parameter Tweedie-Poisson mixture model. It is also proved that the distributions in the extended part of the parameter space are not th...

genotype×environment interactions (geis) can affect breeding programs because they often complicate the evaluation and selection of superior genotypes. this drawback can be reduced by gaining insights into gei processes and genotype adaptation. the objectives of this research were to evaluate: (1) the yield stability of promising wheat lines across locations and (2) the relationship among the t...

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...

Abstract Seven field experiments were conducted at three experiment stations representing major sugarcane producing regions in Egypt. Each comprised a randomized complete block design with replications. Fourteen elite breeding lines typical of those routinely generated the final selection stages programs Egypt, along one check variety (GT54-9) evaluated for cane and sugar yield this study durin...

Stability analysis of grain yield is an efficient tool for the selection varieties adapted to fairly wide cultivation zone. A study aims determine adaptability and stability agronomic performance 10 elite Doubled Haploid (DH) rice genotypes generated through another culture technique, along with local cultivar Umgar as a check under irrigated lowland conditions in three different environments c...

In breeding for plant disease resistance programs, a large number of new improved genotypes are tested over a range of test pathogens or environments and the underlying statistics used to model this system may be rather complicated. Due to ordinal nature of most measured traits of disease responses, some nonparametric methods used for analyzing genotype × environment (GE) interaction in two dat...
