National breeding programs prepped to measure – and boost – genetic gains.
December 14, 2020
By adopting best practices and established modern tools, national agricultural research systems (NARS) are making data-driven decisions to boost genetic improvement. And they are measuring this progress through tracking and setting goals around “genetic gain.”
Genetic gain means improving seed varieties so that they have a better combination of genes that contribute to desired traits such as higher yields, drought resistance or improved nutrition. Or, more technically, genetic gain measures, “the expected or realized change in average breeding value of a population over at least one cycle of selection for a particular trait of index of traits,” according to the CGIAR Excellence in Breeding (EiB)’s breeding process assessment manual.
