Characterization of available genetic diversity is a crucial step in effective crop improvement which provide basis for the analysis of combining ability and exploitation of heterosis of inbred lines in hybrid breeding. Characterization involves evaluation of quantitative and qualitative attributes of a given genotypes in order to differentiate their usefulness, structure, genetic variability and relationships among them. The objectives of this study were to characterize elite maize inbred…

Phenotypic characterization of elite quality protein maize (QPM) inbred lines adapted to tropical-highlands and the association studies using SSR markers.

To characterise newly developed quality protein maize (QPM) inbred lines adapted to tropical-highlands using phenotypic traits and to determine the association with simple sequence repeat (SSR) markers, a study of inbred maize in Ethiopia revealed the presence of two to four distinct genetic groups.

Genetic diversity of African maize inbred lines revealed by SSR markers.

The variability detected using SSR markers could potentially contribute towards effective utilization of the inbred lines for the exploitation of heterosis and formation of genetically diverse source populations in Ethiopian maize improvement programs.

Microsatellite analysis of the correlation between molecular and morphological traits in assorted maize inbred lines.

The aim was to investigate their morphological and genetic diversity, categorise the inbred lines into useful groups based on the molecular profiles and morphological traits, and determine the level of phenotype-genotype correlation.

Parent characterization of quality protein maize (Zea mays L.) and combining ability for tolerance to drought stress

Twenty one CIMMYT-QPM inbred lines were assessed for morpho-agronomic characteristics at the University of Fort Hare (UFH) Research farm during the 2011/2012 summer season to identify adaptable and genetically diverse inbred Lines for use in cultivar development in the Eastern Cape.

Molecular characterization of diverse CIMMYT maize inbred lines from eastern and southern Africa using single nucleotide polymorphic markers

There were high genetic distance and low kinship coefficients among most pairs of lines, clearly indicating the uniqueness of the majority of the inbred lines in these maize breeding programs.

Genetic purity and patterns of relationships among tropical highland adapted quality protein and normal maize inbred lines using microsatellite markers

The model-based population structure, principal coordinate and neighbor-joining cluster analyses revealed the presence of two to three groups, which is generally consistent with pedigree information and partly with heterotic grouping.

Molecular characterization of global maize breeding germplasm based on genome-wide single nucleotide polymorphisms

Pairwise comparisons across three distinct sets of germplasm showed that the elite lines from these diverse breeding pools have been developed with only limited utilization of genetic diversity existing in the center of origin.

Genetic Characterization of CIMMYT Inbred Maize Lines and Open Pollinated Populations Using Large Scale Fingerprinting Methods

Genetic diversity within each population was significantly higher than diversity between populations, indicating that the populations are heterogeneous at the molecular level and that CIMMYT breeders have successfully incorporated considerable genetic diversity into CIMmyT maize germplasm.

Genetic diversity in traditional Ethiopian highland maize accessions assessed by AFLP markers and morphological traits

Three groups of highland accessions, with distinctive genetic profiles and morphological traits were identified, and this information will be useful for further collections and conservation of the unique diversity included in the highland maize landraces of Ethiopia.

Genetic variation in sorghum as revealed by phenotypic and SSR markers: implications for combining ability and heterosis for grain yield

Both marker systems were effective in demarcating sorghum genotypes that provided desirable cross-combinations with high combining ability effects and MPH for grain yield and are recommended as potential parents for Sorghum hybrid breeding in moisture stress environments.
