Abstract

Abstract: High‐throughput genotyping coupled with molecular breeding approaches have dramatically accelerated crop improvement programs. More recently, improved plant phenotyping methods have led to a shift from manual measurements to automated platforms with increased scalability and resolution. Considerable effort has also gone into developing large‐scale downstream processing of the imaging datasets derived from high‐throughput phenotyping (HTP) platforms. However, most available tools require some programming skills. We developed PhenoImage, an open‐source graphical user interface (GUI) based cross‐platform solution for HTP image processing intending to make image analysis accessible to users with either little or no programming skills. The open‐source nature provides the possibility to extend its usability to meet user‐specific requirements. The availability of multiple functions and filtering parameters provides flexibility to analyze images from a wide variety of plant species and platforms. PhenoImage can be run on a personal computer as well as on high‐performance computing clusters. To test the efficacy of the application, we analyzed the LemnaTec Imaging system derived red, green, and blue (RGB) color intensity and plant pigmentation‐based fluorescence shoot images from two plant species: sorghum [ Sorghum bicolor (L.) Moench] and wheat ( Triticum aestivum L.) differing in their physical attributes. In the study, we discuss the development, implementation, and working of the PhenoImage . Core Ideas: PhenoImage is an application for analyzing images derived from high‐throughput phenotyping. Using the tool, users can access image analysis with little or no programming skills. The open‐source nature provides the possibility to further extend its usability.
