Description
The potential of near infrared reflectance spectroscopy for the prediction of nitro-toxin concentrations in 55 Astragalus species was evaluated. A calibration equation based on 90 plant samples selected to represent the range of concentrations of the 55 test species was verified on all remaining samples. The correlation coefficient, r= 0.77, indicated that the technique would be of value for the first cycle of a selection program to reduce nitro-toxin concentrations. The more exact measurements provided by conventional chemical analyses would probably be necessary in advanced cycles of selection if differences among plants or populations were smaller than those detectable by near infrared spectroscopic procedures.
