Identification of High-Yielding Landraces and Hybrids of Maize (Zea mays L.) and the Heritability of Yield-Related Traits in Ghana

A field research was undertaken at the site of Mampong campus University Education, Winneba, Ghana to evaluate parents and progenies seven maize varieties. The main objective study identify high-yielding landraces hybrids heritability yield-related traits using diallel analysis. varieties (parents) used were: Aburopa, Aburonenkatie, Aburohoma, Kamaazie red, yellow, light red Obaatampa. These were crossed complete design generate 49 progenies. their evaluated Randomized Complete Block Design (RCBD) with three replications. In general, Obaatampa performed best for yield traits. General Combining Abilities (GCA) Specific (SCA) significant related suggesting importance both additive non-additive genes in inheritance. Maternal gene effect found control days 50% silking, size seeds, number seeds per cob husk. It is therefore important include reciprocals study. Obaatampa, Aburopa Aburonenkatie general combiner 100 weight. High narrow sense observed tasseling, diameter cob, length weight seeds. progeny X recorded highest SCA followed by Aburonenkatie.
