4D phenotyping of germinating seeds and seedlings as a tool to objectively measure seed quality and improve field establishment and yield of sugar beets [Full subscriber]

Abstract The plant breeding company Strube, in cooperation with the German Fraunhofer Institute for non-destructive testing, has developed an automated high-throughput germination test for sugar beet seeds. The phenoTest permits objective measurement and classification of germinating seeds and resulting seedlings. It is therefore more accurate and provides more information than the conventional ISTA (International Seed Testing Association)-germination test, which relies purely on visual assessment and classification into the categories “normal” or “abnormal”. This differentiation is difficult to standardise, and is, to a significant degree, subjective. The phenoTest is based on three-dimensional (3D) X-ray images. Repeated tests of the same plants…
