The variability of grain yield, seed morphometric and vigour traits of early maturing hybrid maize

Breeding for yield and quality requires the assessment of seed metrics vigour traits. This study, therefore, assessed variability inter-dependence grain (GY), morphometric traits in hybrid maize. Seeds 75 early maturing maize varieties were evaluated four replicates. A field trial laid out a randomised complete block design with three replicates was also conducted Ibadan, Nigeria, to determine hybrids. Data collected on GY, dimension subjected analysis variance. The least significant difference used separate means. Relationships among determined using correlation coefficients, while principal component (PC) performed Significant differences (P<0.001) found Four nine highest yielding hybrids had ECT higher than 30.0 ?sg-1 cm-1. GY correlated diameter (SDT) (0.40**), width (SWD) (0.36**), length (SLG) (0.35**), area (SAR) (0.30**) (SVI) (0.30**). SAG SDT, SLG, thickness (STH) SAR. All one another. PC I explained SWD, SAR SVI, indicating their importance improvement. Seed angle, versatile varietal selection. Identified high qualities can be explored by companies as innovation production business.
