Single-plant Similarity-difference Selection in Wheat Breeding

Diversifying Selection in Plant Breeding

Open access, freely available online " Some qualities nature carefully fi xes and transmits, but some, and those the fi ner, she exhales with the breath of the individual as too costly to perpetuate. But I notice also that they may become fi xed and permanent in any stock, by painting and repainting them on every individual, until at last nature adopts them and bakes them into her porcelain " —...

Genomic Selection in Wheat Breeding using Genotyping-by-Sequencing

21st century wheat breeding: plot selection or plate detection?

The publicly reported limited application of marker-assisted selection (MAS) in wheat breeding programmes to date is reviewed and contrasted with the current situation, in which it has increasingly become technically feasible to tag almost any gene with a microsatellite assay. Although this capability is starting to have an impact on the conduct of large breeding programmes, a much more profoun...

Genetic similarity, breeding distribution range and sexual selection.

Large populations with extensive breeding distributions may sustain greater genetic variability, thus producing a positive relationship between genetic variation and population size. Levels of genetic variability may also be affected by sexual selection, which could either reduce levels because a small fraction of males contribute to the following generation, or augment them by generating genet...

Does genomic selection have a future in plant breeding?

Plant breeding largely depends on phenotypic selection in plots and only for some, often disease-resistance-related traits, uses genetic markers. The more recently developed concept of genomic selection, using a black box approach with no need of prior knowledge about the effect or function of individual markers, has also been proposed as a great opportunity for plant breeding. Several empirica...
