This thesis presents a diversity analysis for 26 tetraploid wheat landraces from the central region of Ethiopia and four cultivars using five markers: morphological traits, chromosome portraits, microsatellites, AFLP and storage proteins.The aim of the study is:To estimate the magnitude of genetic diversity within and between 26 landracesTo identify the pattern of genetic diversity within and between geographical areasTo detect duplications within and between accessionsTo prioritise markers used for estimating genetic diversity in Ethiopian tetraploid wheat landracesThe study revealed a great difference of diversity between the landraces and also demonstrated that the high variation is due to the within component of accessions rather than the between landrace component. No strong variation for genetic composition was observed between plants from different altitudes and subregions. An integrated application of morphological, chromosomal, molecular and storage protein markers for assessing biodiversity in these wheat landraces is strongly recommended.  |
