Research on effectiveness of hyperspectral data on identifying rice of different genotypes

Abstract

The objective of this study is to validate the effectiveness of hyperspectral data and select hyperspectral variables to indicate differences between the non-transgenic parent and the progenies of transgenic rice regardless of gene expression. Statistically significant differences were observed in the range 510-735 nm. More differences could be observed from first-order derivative than from the original reflectance spectra. Spectral position- and index-based variables were calculated to find out the potential indicators. Both the maximum value of first-order derivative and the sum of first-order derivative in the ranges 490-530 and 560-650 nm, photochemical reflectance index (PRI) and modified chlorophyll absorption ratio index (MCARI) were different between parent group and progeny groups of transgenic rice.
