ABSTRACT
Variability for grain nutrients among 561 maize inbred lines were estimated using NIR facility during summer-2014 at the Department of Genetics and Plant Breeding, University of Agricultural Sciences, Bengaluru. The results revealed higher estimates of PCV for grain nutrients suggesting significant difference and prevalence of adequate variability among the inbreds for eighteen grain nutrients. Significant difference was noticed for crude protein, lysine and methionine contents among the inbreds grouped into seven different clusters. Weak association recorded between crude protein and essential amino acids suggested their independent genetic control and the possibility of developing inbred lines rich in lysine, tryptophan, methionine dense protein content which can be subsequently utilized to develop maize hybrids.

Clustering, Essential amino acids, Inbred lines, Maize, NIR, PEM, Protein, Variability.
