Abstract

The aim of the study was to estimate the genetic diversity and correlation analysis among yield and quality traits in 20 local maize populations. The study of variation included the quantity of grain yield, and quality traits such as protein, oil and starch content in grain. Results showed that there were significant differences among the populations. The mean grain yield of all populations was 79.33 g plant-1 and the highest in ‘GBK-7’ (105.13 g plant-1). Protein and oil contents ranged between 11.02 to 13.02% and 2.56 to 5.57%, respectively and starch content varied from 68.58 to 70.92%. First two canonical discriminant functions were significant and the relevance of the first two discriminant functions justifying 95.80% variability among populations. There were also big differences regarding phenotypic correlations. Study suggests that the quality traits are phenotypically and genotypically highly variable and therefore very useful for breeding program.
