Maize is an important food crop in Ethiopia. But its
nutritional quality is poor as its seed protein is devoid of two essential
amino acids (lysine and tryptophan). The objective of the present study was to evaluate the performance of Quality Protein Maize (QPM) hybrids developed by CIMMYT.
Forty three QPM hybrids and 2 checks were tested using 5X9 alpha lattice design
with two replications.
Data were subjected to ANOVA using SAS version 9.2. The
ANOVA revealed very highly significant differences among the genotypes
(p<0.001), for 50% tasseling, ear height, plant count and grain yield. High phenotypic variances were observed for ear height, number of rows/ear, numberof grains/row and grain yield. The phenotypic coefficient of variation and
genotypic coefficient of variation were high for ear height, plant count,
number of rows/ear, number of grains/row and grain yield. The maximum (0.91)
and minimum (0.23) broad sense heritability’s were recorded for number of
rows/ear and days to 50% tasseling respectively.
