Summary, etc. Identification and development of heterotic groups is the key to successful maize hybrid breeding programs. Empirical results from combirring ability studies and experience have generally been used as a means of classifying inbred lines into heterotic groups. These approaches, although effective, are time consuming and expensive. More recently, the use of molecular markers in classifying and refining heterotic groups has been reported with success in temperate maize germplasm (Dubreuli et al. 1996) and is in its infancy stage in tropical maize germplasm (Warburton et al. 2002). The advantage of molecular markers over other techniques to assign lines and populations into heterotic groups is reflected in the large numbers of markers in the genome of crop plants, lack of environmental interaction, and their ability to be organized into linkage groups. This study evaluated the potential usefulness of molecular markers in identifying and refining heterotic groups of inbred lines commonly used in Zimbabwe.
