Based on analysis of variance using the Nested design - Random model, the level of genetic and phenotypic variance, as well as heritability for grain yield and yield components for S1 and Hs progenies were determined in two early maturity synthetic populations of maize. The results obtained indicate a satisfactory level of variability present for all observed traits in S1 and HS progenies of both populations. Thus, the principal prerequisite for the successful application of breeding methods is fulfilled. The higher level of genetic variance for grain yield for ZP Syn 101/9 in relation to ZP Syn 99/9 gives a better starting base for the application of recurrent selection methods.
