| Abstract: | The aims of this study were to assess the linear relationships between agronomic and nutritional traits and identify promising traits for indirect selection in transgenic genotypes of maize. Eighteen transgenic maize genotypes were assessed in randomized blocks with three replications. The agronomic (number of days from sowing until male flowering, number of days from sowing until female flowering, plant height, ear insertion height and grain yield) and nutritional (crude protein, ether extract, crude fiber, starch and amylose) traits were measured. Analysis of variance was run for each of the 10 traits and phenotypic and genotypic correlation coefficient matrices estimated. Ridge path analysis were performed the nutritional traits were treated as main variable (dependent) and agronomic traits as explanatory variables (independents). The number of days from sowing until female flowering has a positive linear relationship to crude protein, ether extract and starch. Plant height has a positive linear relationship to crude fiber. Ear height has a positive linear relationship to amylose. Grain yield has a positive linear relationship to starch. The number of days from sowing until male flowering, plant height, ear height and grain yield can be used indirect selection in maize. |
