Six hybrid Chinese maize varieties with a local best were evaluated for their growth and yield performance with a view to adoption in South east agroecological zone of Nigeria. A Randomised Complete Block (RCBD) Design was used. The cultivars did not differ (p ≤0.05) significantly in some growth parameters, this included emergence percentage at 5DAP (days after planting), plant height at both 4WAP and 6WAP (weeks after planting). Tasseling and silking differed significantly, the exotic varieties tassled and silked better than the control at 8WAP and 10WAP respectively. The only significantly different yield parameters were the length and weight of undehusked cobs, circumference of dehusked cobs. The exotic varieties matured earlier than the control between 11 to 14WAP and 16WAP respectively. There was no significant difference in the grain yield between the maize varieties. The Chinese varieties did not show a marked difference in grain yield compared to the local
