Abstract
One of the objectives of this paper was to determine relationship between
grain yield and yield components, in S1 and HS progenies of one early
synthetic maize population. Grain yield was in high significant, medium
strong and strong association with all studied yield components, in both
populations. The strongest correlation was recorded between grain yield and
1000-kernel weight (S1 progenies rg = 0.684; HS progenies rg = 0.633).
Between other studied traits, the highest values of genotypic coefficient of
correlations were found between 1000-kernel weight and kernel depth in S1
population, and 1000-kernel weight and ear length in HS population. Also,
objective of this research was founding the direct and indirect effects of
yield components on grain yield. Desirable, high significant influence on
grain yield, in path coefficient analysis, was found for 1000-kernel weight
and kernel row number, and in S1 and HS progenies, and for ear length in
population of S1 progenies. Kernel depth has undesirable direct effect on
grain yield, in both populations.
