In cotton crops, the seed yield significantly contributes with success of any cultivar. However, other traits are considered when an ideotype is pointed out in selection, such as fiber quality traits. The aim this study was to applied genotype by yield*trait (GYT) biplot a multi-environment trial data genotypes and selected best genotypes. For end, thirteen from nineteen trials were assessed. S...

In an earlier investigation (Burger et al., 2000) five sediment cores near the Rodrigues Triple Junction in the Indian Ocean were studied applying classical statistical methods (fuzzy c-means clustering, linear mixing model, principal component analysis) for the extraction of endmembers and evaluating the spatial and temporal variation of geochemical signals. Three main factors of sedimentation...

There is an ever-increasing need to identify new feed resources in developing countries and the types of forages used tend to be more complex in terms of chemical composition. Near infrared re ̄ectance spectroscopy (NIRS) has the potential to aid the evaluation of forages and in this study was employed to compare and classify Gliricidia spp. provenances. Multivariate statistical techniques, incl...

ASEAN's global competitiveness requires institutional and ASEAN countries appear to be a formidable economic actors in protecting the interests at same time having an open system that indicates readiness of compete with strength entire region world. In this case measurement factors become important aspects state enterprises face competition. This study was conducted determine how competitive Bi...

Multivariate binary data are increasingly frequent in practice. Although some adaptations of principal component analysis used to reduce dimensionality for this kind data, none them provide a simultaneous representation rows and columns (biplot). Recently, technique named logistic biplot (LB) has been developed represent the matrix simultaneously, even though algorithm fit parameters is too com...

Maize (Zea mays L.) yield performance is determined by the effects of genotype and environment, × environment interaction (GEI). A complete diallel crosses 11 QPM inbred lines were evaluated under both low optimum soil nitrogen environments to identify high grain stability single-cross hybrids in six environments. The results analysis variance showed that variations among attributable genotypes...

The aim of this work is to investigate how the spatial variability of soil properties and soil erodibility (K factor) were affected by the changes in land use allowed by irrigation with water from a reservoir in a semiarid area. To this end, three areas representative of different land uses (agroforestry grassland, lucerne crop and olive orchard) were studied within a 900 ha farm. The interrela...
