METHODS AND SYSTEMS FOR PLANT PERFORMANCE ANALYSIS

摘要

Method and systems for assessing wide area performance of a crop variety usi ng a linear mixed model that incorporates geologic statistical components and includes parameters for fixed effects, random effects and covariance (J20). A wide area database is constructed that includes covariate data, spatial coordinates of testing locations of one or more crop varieties, geographic areas in which the testing location reside, and performance trait values of one or more crop varieties (H25, H30). The parameters for the fixed effects, random effects and covariances are estimated by fitting the linear mixed mod el with data in the wide area database. Long term expected performance of the crop variety may be estimated using the parameter estimates. Average performance of the crop variety for a given time period may be predicted usi ng the parameter estimates.
