Increased
production and productivity of maize will be attained by selection of
best hybrids. However, selection on the basis of grain yield alone is
usually not effective, because grain yield is a complex quantitative
trait that depends on a number of factors. The objective of this study
was to determine trait association and direct and indirect effects of
yield related traits on grain yield of elite maize hybrids. A total of
eleven pipeline maize hybrids and two standard checks (BH546 and BH547)
were evaluated in a randomized complete block design with three
replications during the 2015 main cropping season at Northwestern
Ethiopia. Mean squares due to genotypes were highly significant for most
grain yield and yield related traits indicating the existence of genetic
variation among the evaluated genotypes. Grain yield showed positive and
significant phenotypic and genotypic association with number of kernels
per row. For other traits, the strongest positive phenotypic and
genotypic association was observed between number of kernel rows per ear
and ear diameter. Positive association between two desirable traits
helps the plant breeder to easily improve both traits simultaneously.
Ear diameter, number of kernels per row and ear length had positive
phenotypic and genotypic direct effect on grain yield. This implied that
ear diameter; ear length and number of kernels per row are important
traits in determining yield performance. The information generated by
this study could be useful for researchers who need to develop high
yielding maize hybrids. How to cite this article: Mesenbet Z, Zeleke H, Wolde L (2017). Correlation and Path Coefficient Analysis of Grain Yield and Yield attributed of elite line of Maize (Zea mays L.) Hybrids. Acad. Res. J. Agri. Sci. Res. 5(1): 1-9
