CONSTRUCTION OF AN IMAGE-BASED GERMPLASM DATA-BASE FOR PHASEOLUS SPP

In this paper a hardware-software computer aided germplasm classificat ion and evaluation system is described. Sample data (Phaseolus spp. se eds) were acquired into the system through a video camera. The resulti ng digital images were stored into an IPGRI-compliant database structu re running in a graphical operating environment. The data base structu re was based on a series of forms, with the capability of simultaneous display of image and data fields. Within the forms, an original syste m based on pop-up menus and icons for fast evaluation and classificati on of bean accessions was implemented. This gives the operator the pos sibility to choose among pre-stored standard sample images, the one wh ich matches better the actual accession phenotype. Furthermore, protot ype fundamental operating capabilities and possible implementations in the fields of genetics, breeding and germplasm storage and classifica tion are discussed.
