Led by Thiago P. Oliveira Summary Plant breeding programmes are a complex network of a multitude of operations and decisions. Therefore quantifying which operations and decisions drive genetic change in plant breeding is challenging. Traditionally we measure the genetic change with a phenotypic or genetic trend, but these trends measure only change in the mean. To understand genetic change and its drivers more comprehensively, we also need to measure changes in genetic mean and variance and evaluate drivers of changes in mean and variance.
