Cereals are the basis of global agriculture providing more than half of the human food consumption. In Spain, barley is the main crop in terms of growing area, mostly in the poorest agricultural areas. In semiarid areas crop productivity is not only limited by drought, but also by high temperatures at the end of the growth cycle. An increased use of ‘local’ germplasm could lead to the selection of varieties adapted to specific regional conditions. The use of a barley variety like ‘Albacete’, with its proven adaptation to semiarid conditions, can be an excellent option. It has been hypothesized that the high popularity of ‘Albacete’ with farmers particularly in semi-arid areas where barley is grown under rain fed conditions, may be due to the presence of a special form of chromosomal interchange, a reciprocal translocation. This thesis provides a cytological, genetic and agronomic characterization of this reciprocal translocation.
