EMR Model Hudson Valley Honeycrisp Bitter Pit Prediction
Dan Donahue, Tree Fruit Specialist
Eastern New York Commercial Horticulture
The data presented in Figure 1 are from 19 Hudson Valley (HV) M.9 clone, M.26 and Bud.9 blocks that have been monitored annually since 2016. Blue bars represent observed bitter pit (BP), red bars represent EMR (Environment, Mineral profile, and Rootstock model) predicted values. In this "view from 10,000 feet", the EMR model has been reasonably accurate in predicting the HV BP trend in five of the six seasons, while over-predicting BP in 2018. As a practical matter, for a prediction model to be useful it must emphasize accuracy in the range of 0-20% BP incidence.
