Abstract: | Emmer wheat is hulled wheat that was wide cultivated in Spain at the past. Actually, the most of this germplasm is conserved
in Germplasm Banks, and only two small populations have been found in Asturias (North of Spain) in a recent collecting mission.
In this work, a collection of 31 Spanish emmer lines developed from identical number of accessions of two Germplasm Banks
was analysed for morphological spike traits and seed storage protein composition. Up to seven different botanical varieties
were detected, which suggest the presence of a wide diversity, although lower than the historically described 10 botanical
varieties. At level of seed storage proteins, the lines showed a high diversity, although the new alleles were present with
low frequency in materials with scarce agronomic interest for the farmers (var. atratum, var. lagascae or var. pycnurum). This last circumstance could translate in a lost of variability by genetic drift. |
