Development of a NITS Calibration for Starch Amylose Using Materials from an Amylomaze VII Yield Trial

Previously, an attempt was made to develop a near infrared transmittance spectroscopy (NITS) calibration. The materials used to develop this calibration included a number of genotypes that varied widely in amylose content. The genotypes represented many mutant alleles including waxy (wx), sugary-2, normal, and amylose extender (ae). Although a relatively high correlation coefficient (r²) was observed, it was associated with a very high error term. For this reason the NITS amylose calibration did not serve well as a screening tool for the development of high amylose corn. The objective of this project is to develop a calibration using a set of genotypes that has a more narrow range of amylose content, specifically between 55% and 75%. The performance of our calibration will be reported for this study utilizing not only the correlation coefficient, but the standard error of prediction (SEP).
