Abstract:
Therefore, the experiment was conducted during Rabi, 2022 at College Farm, M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi, Odisha, India to estimate the character association in 51 inbred lines and one check tested in randomized block design with three replications. The objective was to determine the phenotypic and genotypic relationships between traits and to evaluate the direct and indirect effects of attributes on grain yield in maize. In order to increase the effectiveness of the selection, character association studies will be helpful in determining the relationship between the yield and its components. In light of this, 51 inbred and one check of maize was employed in the current study's investigation of the correlation coefficient and path analysis using 16 quantitative and qualitative criteria. According to correlation studies, there is a positive non-significant correlation between the number of ears per plant, plant height, and days to maturity at both the genotypic and phenotypic levels and the grain yield per plant, as well as a positive significant correlation between the ear height, ear length, number of kernel rows per ear, number of kernels per row, and 100 kernel weight. Therefore, choosing any one of these traits will enhance the other characters as well as raise the production of grain yield per plant. The number of kernels per row, 100 kernel weight, and number of rows per ear were found to have the strongest positive direct effects on grain yield per plant, and their correlations with grain yield plant-1 were also considerably favourable. As a result, the current research may help in the development of high yielding varieties and the reliable selection of parental lines based on the aforementioned characteristics.
