The development of agronomically adopted varieties of maize with improved amino acid balance benefits livestock producers and people who depend on maize for dietary protein. The present study was carried out with an aim to compare and evaluate growth and biochemical characteristics in three genotypes of maize, GSF-2 and two quality protein maize (QPM) inbred lines, CM-137 and CM-138. Germination rate, root and shoot length regarded as growth parameters have shown to be significantly higher in CM-137 and CM-138 genotypes than the GSF-2. Protein and RNA contents were found higher in the leaves of GSF-2 than the quality protein maize genotypes, indicating high metabolic activity of the former. Total protein content and amino acid lysine and tryptophan contents in the seed flour of CM-137 and CM-138 were higher than GSF-2 genotype. Higher proline content was noted in QPM varieties than the GSF-2; however, the total phenolic content was higher and same for CM-137 and GSF-2. Quality protein maize varieties indicated more resistance towards drought and heavy metals, which could be correlated with higher proline levels in seed. Salinity had no significant effect on all the three genotypes. Results indicated significant increase in growth, protein, lysine and tryptophan content in quality protein maize genotypes, CM-137 and CM-138 than GSF-2.
