Abstract

A novel analytical approach was used to identify associations between NIR spectral fingerprints and segments of chromosomes indicating that genetic factors contribute to variation in NIR spectra.

The basis for identifying the genetic factors was the process of removing environmental and experimental variability from the spectra using spatial mixed models.

These corrected spectra were combined with the analysis of wheat lines from a genetically structured population derived from a Carnamah by WAWHT2046 doubled haploid (DH) set of F1 progeny.

The association of chromosome segments with variations in particular wavelengths in the NIR spectra was established using all-subset regression and canonical correlation methodology.
