The core of Darwin’s theory includes two ideas about natural selection: that it explains the evolution of the organisms’ characteristics and that it pushes these characteristics towards an optimum of organization and design. While the... more
Bayesian analysis via Gibbs sampling, restricted maximum likelihood (REML), and Method R were used to estimate variance components for several models of simulated data. Four simulated data sets that included direct genetic effects and... more
Molecular markers (RAPD, AFLP and microsatellites) were used to generate a linkage map and to identify QTLs associated to witches' broom (Crinipellis perniciosa) resistance in cacao (Theobroma cacao), using 82 individuals of an F2... more
Application of Marker-Assisted Selection in Crop Breed- ing. Muhammad Azrai. DNA-based technology has dramat- ically enhanced the efficiency of plant breeding, especially when selections are to be done under unfavourable condi- tions.... more
The relative strength of different types of directional selection has seldom been compared directly in natural populations. A recent meta-analysis of phenotypic selection studies in natural populations suggested that directional sexual... more
Background. In order to properly direct the breeding work of cultivars of a given potato earliness group it is necessary to know the range of variability and relationships between their characteristics, both in a given year and between... more
The advent of molecular markers as a tool to aid selection has provided plant breeders with the opportunity to rapidly deliver superior genetic solutions to problems in agricultural production systems. However, a major constraint to the... more
