The study was conducted with the aim of evaluating the performance of 19 maize hybrids
which were released for production in high potential maize zones of Ethiopia by three foreign
private (Pioneer hybrid Seeds Ethiopia, SeedCo, Syngenta Agro-services AG-Ethiopia) and
three public (Baka ARC, Malkasa ARC, Ambo Plant Protection Centre) institutions in
Ethiopia. The analysis of variance revealed significant differences (P<0.01) between hybrids
for all measured parameters except for the root lodging and stalk lodging. The quantitative
characters studied were days to maturity, days to silking, plant height, ear height and grain
yield. Grain yield being significantly highest for SCDUMA43. The present study generally
revealed that BHQPY546, P3812W, MHJ30 and SCDUMA43 had higher grain yield
compared to BH660 BH547, BH540, SC627, BH543 BH661, 30G19, BH670, Wenchi, BH546,
MH138, BHQP542, BHJ 40, Jibat and AMH760Q. Among the varieties MH130, SCDUMA43
and Wenchi are early maturing variety. While BH140, BH661, BH670 andAMH760Q are late
maturing varieties. The significant difference (P<O. 05) in grain yield and highly significant
difference ( P < 0.01)/or other agronomic character among various varieties were probably
due to diverse back ground from which the genotypes used in the present study were
developed. A significant difference in number of cobs per plant was evident from the above
data. The significantly minimum grain yield (3302. 832) was obtained in BHQP542. More
grain yield in SCDUMA43 and closely related performance of P3812W can be correlated to
plant density, number of cobs per plant, number of grains per row. In the present study,
hybrids that had mean ( 7910. 756kg/ha) values have better performance than other variety
can propose or an indication on the process of selecting suitable hybrids to grow in the
localised Bahir Dar region as an sustainable selective maize hybrid crop. High heritability
of date of an thesis and date of silking indicated that influence of environment on these
characters is negligible or low. Hence plant breeder may use these characters in maize
