About this app

OneKK is an app designed to analyze seed lots. Its name comes from the one thousand kernel weight that is commonly used as a selection criteria in plant breeding programs. OneKK extracts seed morphology from images captured by phone and tablet cameras. Coins included in each captured image on a light box background translate pixel measurements of seeds to actual size.

For measurement of thousand kernel weight, the total number of seeds are counted and divided by the total weight. For weight measurements, the app is compatible with Ohause Bluetooth scales.

OneKK is part of the broader PhenoApps initiative, an effort to modernize plant breeding and genetics data collection and organization via by developing new strategies and tools for data capture.
