Contenido: 	Abstract: Near-infrared reØectance spectroscopy (NIRS) was used to predict the chemical composition of whole maize plants (Zea mays
L) in breeding programmes at INIA La Estanzuela, Uruguay.Four hundred samples (n= 400) were scanned from 400 to 2500 nm in an NIRS 6500 monochromator
(NIRSystems, Silver Spring, MD, USA). ModiÆed partial least squares (MPLS) regression was applied to  scatter-corrected  spectra  (SNV  and detrend).  Calibration  models  for  NIRS  measurements  gave multivariate  correlation  coefÆcients  of  determination  (R2 )  and  standard  errors  of  cross-validation
(SECV) of 0.72 (SECV 9.5), 0.96 (SECV 7.7), 0.98 (SECV 16.5), 0.96 (SECV 34.3), 0.98 (SECV 17.8) and 0.98  (SECV  6.1)  for  dry  matter  (DM),  crude  protein  (CP),  acid  detergent  Æbre  (ADF),  neutral detergent Æbre (NDF), in vitro organic matter digestibility (IVOMD) and ash in g kg ?1 on a dry weight
basis respectively. This paper shows the potential of NIRS to predict the chemical composition of whole maize plants as a routine method in breeding programmes and for farmer advice.
