Analysis of the genetic diversity of wild Spanish populations of the genus Hordeum through the study of their endosperm proteins
A study was made of the genetic variability of 101 barley populations belonging to the four, wild, Spanish species of the genus Hordeum (the autogamous H. marinum subspp. marinum and gussoneanum, and H. murinum subspp. murinum and leporinum, plus the allogamous species H. bulbosum and H. secalinum). Electrophoresis of endosperm proteins was performed using a large number of individuals from each population sampled, in order to determine intra- and interpopulational variation. The distribution of variability observed by population and taxonomic unit, is closely related to the breeding system. Hordeum bulbosum showed the greatest intrapopulational variability and H. marinum subsp. gussoneanum the least. In contrast to the autogamous species, the allogamous species showed low levels of interpopulational variation.
