Abstract

A diverse collection of Teff [Eragrostis tef (Zucc.)Trotter] lines was characterized for a wide range of traits, ranging from agronomic to final Injera sensory parameters, under well-irrigated Mediterranean spring conditions. The lines tested were collected from single plants presenting lodging resistance at the site of collection and their traits were characterized herein. An early type of lodging was observed, which was most likely triggered by a fast and sharp inflorescence weight increase. Other lines were ‘strong’ enough to carry the inflorescence most of the grain-filling period, up to a point where strong lodging occurred and plants where totally bent to the ground. Three mixed color seeds lines were found at single plant collection or after propagation. These were separated into ‘white’ and ‘brown’ seeds and were characterized separately under field conditions. The newly ‘brown’ lines appear to be the result of a rather recent non-self (external) airborne fertilization from a dark pollen donor. Some of these hybrids were found to be promising in terms of Injera sensory traits. Integration between a wide range of parameters and the correlations obtained between agronomic and sensory traits may improve our ability to breed towards a “real world” better end-product.
