Inheritance of Nitrogen Use Efficiency in Inbred Progenies of Tropical Maize Based on Multivariate Diallel Analysis

Table 3

Empirical BLUP estimation of the mean variation of the maximum and minimum values of the specific combining ability (SCA) of the hybrids synthesized between different groups of progenies, of the variances of the GCA and SCA and their interactions (GCA × Envir, SCA × Envir).
