Grain producers, handlers and processors; allied equipment, technology & service suppliers.
PHERC includes a fully functional grain handling center and a new 16-bin state-of-the-art pilot facility as well as four on-campus laboratories (Grain Quality Lab, Physical Properties Lab, Mycotoxin Lab, and Stored Product Pests Lab.
Help Indiana soybean growers and seed producers identify the best varieties that will consistently yield the most bushels and contain maximum amounts of end-use quality traits.
*Currently sponsored by the Indiana Soybean Board; in collaboration with ICIA
Quantify differences in Corn Hybrid Properties Affecting Conditioning and Processing*
Yellow “normal”, Yellow Food Corn, White Corn, High Oil, Waxy, High lysine, Highly fermentable corn
Water absorption rate, kernel density, pericarp thickness and structure, germ to endosperm ratio, kernel hardness, kernel dimensions and shape, fiber content, color (proxy for carotenoid)
*Purdue and GMPRC (Manhattan, KS) NC-213 Proposal
- Reduce time required for viability testing
- Sorting non-viable from Viable seeds
- Respiration monitoring (CO2 or O2:CO2)
- NIR of individual kernels for rapid assessment
of germ viability
- Biochemical Indicators of seed viability
Good quality seeds

Seeds subjected to accelerated aging
Note: The distinctions related to accelerated aging are not always this clear. Incubation temperature was 23C.
