Genetic diversity of eight millet genera assessed by using molecular and morphological markers

Popis výsledku v původním jazyce

To our knowledge, this is the first attempt to use morphological and molecular markers to investigate the genetic relationships of eight millet genera. Both of these markers confirmed the 50 presence of a high level of genetic variability among and within the different millet genera. The study revealed that, in some cases, the genus boundaries were not very rigid, and accessions of given genera (Panicum, Eleusine, Pennisetum) were scattered throughout the dendrogram. Although AFLP 55 markers could not clearly distinguish some individual species and their relatedness, the reason for this failure is attributed to a limited number of samples rather than the methods implemented. Considering all of these findings, this study has demonstrated that AFLP markers can be used for reliably detecting levels of DNA polymorphism and genetic relationships in millets. The genetic diversity data from the millet accessions can provide 5 the framework for the molecular genetic dissection of complex millet relationships. The data can be used as a guide until a more detailed study is completed. Furthermore, knowledge of genetic variation within and among millet species and genera provides essential 10 information for the formulation of appropriate management strategies for millet genetic resource conservation. Finally, the findings of this study may also be useful for designing effective breeding programs. The genetic variability within millets provides an important source of agronomic traits suitable to 15 the conditions of a changing climate. These traits might be source of new adaptations to pest and disease resistance as well as drought resistance.
