Interrelationships among grain yield and its component traits in maize genotypes

Abstract

The character association and direct, indirect effects for yield and its contributing characters among 80 maize (Zea mays L.) genotypes was assessed at experimental field of Agricultural Research Station (ARS), Karimnagar, Telangana, during kharif, 2024. The characters like ear girth, ear height, number of kernels per row, number of kernel rows per ear are positively correlated with grain yield. The characters ear girth, test weight, number of kernels per row, ear length shows highest positive direct effect on grain yield at genotypic level and test weight ear length, number of kernels per row, number of kernel rows per ear sow highest positive direct effect on grain yield at phenotypic level.
