Stalk lodging destroys billions of dollars’ worth of maize crops in the United States every year. In order to breed for lodging resistance breeders must first be able to accurately phenotype for the traits that influence it. Past strategies to breed for lodging resistance have correlated non-destructive rind penetration resistance test values with strength, but this overlooks key factors that influence lodging resistance like stalk diameter, rind thickness, and pith density. In this poster, we present a modified rind penetration phenotyping process that rapidly captures and quantifies these additional morphological traits, allowing plant breeders to more effectively breed for lodging resistance. The Stalk Puncture Device will allow these rapid phenotyping tests to be conducted in the field without the need to harvest the stalks. This hand-held device drives the needle through a cornstalk while recording displacement and force. The data is rapidly processed using a dual Arduino set up that allows for simultaneous measurement and movement control. The intuitively designed user interface will allow operators to input metadata and visualize post-test data in real time. The device is battery powered for mobility and stores organized data in a micro SD card for data post-processing off-site. This device provides clear advantages over traditional rind penetration phenotyping protocols. Specifically, it allows breeders to rapidly phenotype in a field environment without the need to harvest specimens, provides a rich data set of key morphological parameters, and will allow both real-time data visualization and data storage for offsite post-processing. This method will allow breeders to rapidly and easily phenotype for traits that are directly correlated to stalk lodging resistance, while avoiding the pitfalls of previous similar phenotyping approaches.
