SEQUENTIAL SAMPLING FOR UNEXPECTED DAMAGE TO BT CORN FOR CORN ROOTWORM CONTROL

摘要

Methods are provided for the sequential sampling of pest resistant crop plants for determining resistance of a pest to a pesticidal activity of a pest resistant crop plant. The methods involve choosing a plant in a plot in an unbiased sampling manner. Trait expression is determined for each of the transgenic pest resistant plants to identify plants having pesticidal activity, and plants determined to have the pesticidal activity are a batch. Then the pest damage to the roots of the batch is rated with each batch having at least about five plants to determine the resistance of pests in the plot.
