Understanding both, phenotypic and genetic variations among plants, starts with an adequate experimental design to provide sensible phenotypic and genotypic information. To set-up an experimental design, first the main question has to be defined, whereupon recommendations regarding e.g. size of the multi-parental population, number of crossings, traits of interest with measuring protocols, and environments (multi-environmental trails) can be made. Overall, Genetwister offers assistance in the designing of experiments, with awareness of breeding program’s practical considerations. (sentence is repeated in the above paragraph).
Genomic selection (GS) is an alternative to marker-assisted selection, which can accelerate the genetic gain through shorter breeding cycles. Genetwister is implementing new breeding schemes and methods that integrate GS for crop improvement.
