Heritability estimate formula

WitrynaImplements marker-based estimation of heritability when observations on genetically identical replicates are available. These can be either observations on individual plants or plot-level data in a field trial. Heritability can then be estimated using a mixed model for the individual plant or plot data. For comparison, also mixed-model based estimation … Witrynalection experiments can be used to estimate h2 which represents an effective tool to estimate resistance devel-opment rate. The realized heritability value can be used to predict future resistance status to any pesticide in cer - tain pests (Abbas and Shad 2015). Realized heritability is defined as the contribution of additive genetic vari-
