**4. Recognizable identity**

Landrace must be intrinsically highly genetically diverse and recognized as a distinct entity via common-shared traits. These traits will allow the distinction of one landrace from another or from modern cultivars for the same crop. They will sometimes give rise to landrace names, but at other times, names may be determined by other factors such as use or origin. Therefore, landraces 'are each identifiable and usually have local names' [7], 'are recognized morphologically' [14], 'have a local name,' 'are a farmer selection based on local characteristics (specific use, local market, horticultural practices and locally adapted)' and 'are heterogeneous populations with a similar trait'.

However, this characteristic may be difficult to be applied universally as landraces identified on the basis of common names can be misleading because of non-associated synonyms and homonyms. Many disparate landraces may be named after their early flowering capability or seed color, for example. A landrace may be recognized by different names in different countries or communities [36], or conversely quite different landraces can be designated with the same name [14]. These factors contribute to one of the main problems associated with landraces, namely, their consistent identification and the determination of which traits can be consistently used to define the identity of a specific landrace.
