Variation in Spanish cultivated einkorn wheat (Triticum monococcum L. ssp. monococcum) as determined by morphological traits and waxy proteins

A collection of 29 lines of Spanish einkorn wheat (Triticum monococcum L. ssp. monococcum) were analysed for morphological traits and waxy proteins. Four different botanical varieties were detected in the collection on the basis of the morphological traits. For the waxy proteins, no polymorphism has been described in previous works in wheat diploid species. In the current materials, two different alleles were found, namely Wx-Am1a and Wx-Am1a′. The allele Wx-Am1a′ that presents less mobility than the Wx-Am1a, has not been previously described and was only found in one line.
