Rank correlation among different statistical models in ranking of winter wheat genotypes

Water Stress Effects on Winter and Spring Leaves Anatomy of Different Wheat (Triticumaestivum L.) Genotypes

Water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of SB University of Kerman using five wheat cultivars.Xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. Results showed that significant difference exists...

Analisis of phytomass in 36 iranian winter wheat (triticum aestivum L. em. thell.) genotypes

Yield Stability Analysis of Wheat Genotypes in Large Number of Environments Using Univariate Parametric Statistical Models

-Wheat is the most important crop of many countries including Pakistan. Assessment of Yield stability of wheat in different environments has been an important issue for wheat growers and horticulturists. In present paper yield stability of wheat genotypes is assessed at different research institutions/stations across the country using univariate parametric stability models and interrelationship...

Adjusting yield components under different levels of N applications in winter wheat

This work presents information on the patterns of yield determination by yield components as a function of the level of management of the crop. The data used for the analyses were obtained from 8 field experiments located across Poland in 2009 and 2010. 25 winter wheat cultivars were evaluated at two management levels, i.e., at a low input of nitrogen fertilisation and pesticides and at a h...

Computing Parametric Ranking Models via Rank-Breaking

Rank breaking is a methodology introduced by Azari Soufiani et al. (2013a) for applying a Generalized Method of Moments (GMM) algorithm to the estimation of parametric ranking models. Breaking takes full rankings and breaks, or splits them up, into counts for pairs of alternatives that occur in particular positions (e.g., first place and second place, second place and third place). GMMs are of ...
