|Erna Lukina directs the use of a hand-held sensor developed by Dr. Marvin Stone at Oklahoma State University near the CIMMYT headquarters (El Batan) for use in selecting plant genotypes with improved NUE.|
In September 1999, spectral data were collected from seven international cereal nurseries located in Toluca and El Batan, Mexico. Spectral readings in red and near-infrared (NIR) region were used to calculate the normalized difference vegetative index (NDVI).
The major objective of this work is to asses the applicability of hand-held sensor in selection of productive cereal genotypes.
We assume that correlation of NDVI values with grain yield demonstrates the genotype potential in terms of yield and nitrogen use efficiency.
