Abstract


 

Maize (Zea mays L.) is the third most important cereal crop after wheat and rice in the world. Field experiments were conducted at Institute for Agricultural Research, Samaru (11°11´N; 07°38’E) in the Northern Guinea Savanna and National Horticultural Research Institute, Bagauda (11°33´N; 8°23´E) in the Sudan Savannah ecological zones of Nigeria between July-October, 2014 rainy season to estimate the heritability and expected genetic advance in the white maize inbred and to evaluate suitable selection criteria for further breeding. The study comprised of 6 parental lines, 15 hybrids and 4 checks which were laid out in partially balanced lattice design with three replications. The study revealed  high PCV and GCV values for  days to 50% silking (24.49, 22.83), anthesis silking interval (26.26, 27.07), plant height (29.26, 27.07), days to maturity (115.61, 86.56), ear height (72.36, 69.59), ear length (33.63, 22.58), ear diameter (37.58, 29.42), field weight (104.99, 94.58), moisture content at harvest (43.72,35.42) and grain yield (72.34, 69.56. The magnitude of phenotypic coefficient of variation (PCV) estimates in the present study was found to be slightly higher than their respective genotypic coefficient of variations (GCV) for all the studied traits. The result also indicated that days to 50% silking (88%, 75.46), anthesis silking interval (84%, 38.09), plant height (92%, 9.23), ear length (67%, 36.31), ear diameter (81%, 43.84) and yield (92%, 10380.24) had high heritability accompanied with high genetic advance. The significant difference (p≤ 0.05) among the genotypes across locations for most traits evaluated indicates the presence of genetic variability among the genotypes.  PCV and GCV values recorded revealed the possibility of improving this traits through selection. The genotypes with high heritability coupled with high genetic advance could be selected and improved at early generation.
