摘要: Tef is an important cereal crop in Ethiopia. This study was conducted to investigate (1) genetic diversity within and among three Eragrostis species (E. tef, E. pilosa curvula), (2) the relationship between curvula. A total of 529 AFLP markers were obtained, out which 58% (368) polymorphic, using 10 primer, combinations. The separated distinctly amplified fragment length polymorphism (AFLP), However, revealed at morphological trait level not commensurate with that observed for AFLP. due small number traits available their interaction environment. Within ‘Rubicunda’ DZ-01-1093 found be distantly related rest tef accessions. such most diverse followed by curvula tef. Moreover, more closely than Therefore, further needed accessions a crossing programme generate population selection and/or mapping. 19 cultivars or had one unique fragments primers, indicating potential technology fingerprinting breeding seed multiplication programme.
