dc.description.abstractLocal populations of maize are valuable resources to maintain the genetic variability within the species. Breeding programs in many different countries try to characterize and exploit such germplasm. The objective of this study was to evaluate 192 Turkish maize landraces for their variation in terms of protein ratio, the amino acids that affect the protein quality, starch ratio as well as its fractions. Field experiment was carried out at the Crop Research and Application Unit of CanakkaleOnsekiz Mart University Agricultural Faculty Farm, and used and augmented design with 6 blocks. Each block contained 32 landraces and 7 standard hybrids. Data were collected on protein, lysine, tryptophan, starch, amylose, and amylopectin content. Analysis of variance was run, and genetic calculations were utilized to determine the heritability values. The results suggested that Turkish maize landraces possess a considerable variation for protein and starch traits. The ranges determined for protein, starch, amylose, amylopectin, lysine, and tryptophan were 6.56-16.50%, 56.38-79.63%, 2.09-35.25%, 64.75-97.91%, 0.12-0.93%, and 0.03-0.09%, respectively. The broad sense heritability values for the investigated traits were between 16-53%. Several landraces were detected to be superior to the standard varieties for some traits and considered to be valuable genetic material for the breeding studies to come.
