Abstract EN
The objective of our study was to characterize and determine the patterns of genetic control in relation to tolerance and efficiency of nitrogen use by means of a complete diallel cross involving contrasting inbred progenies of tropical maize based on a univariate approach within the perspective of a multivariate mixed model.
Eleven progenies, previously classified regarding the tolerance and responsiveness to nitrogen, were crossed in a complete diallel cross.
Fifty-five hybrids were obtained.
The hybrids and the progenies were evaluated at two different nitrogen levels, in two locations.
The grain yield was measured as well as its yield components.
The heritability values between the higher and lower nitrogen input environment did not differ among themselves.
It was observed that the general combining ability values were similar for both approaches univariate and multivariate, when it was analyzed within each location and nitrogen level.
The estimate of variance of the specific combining ability was higher than general combining ability estimate and the ratio between them was 0.54.
The univariate and multivariate approaches are equivalent in experiments with good precision and high heritability.
The nonadditive genetic effects exhibit greater quantities than the additive genetic effects for the genetic control of nitrogen use efficiency.
