Popis: The basis of accelerated breeding comes from the fact that crop losses are enormous and underestimated. Thus, it becomes essential to gain a broader perspective of the loss factors and of the basic mechanisms used by plants to cope with biotic and abiotic stress. From this knowledge, alternatives to the traditional multilocation tests can be developed in order to identify lines that combine high yield potential with reduced GxE interactions. We explain here how to choose and apply stresses that accelerate breeding. A careful use of certain stresses such as barley yellow dwarf virus (BYDV) may facilitate selection against an array of other unrelated stresses. Understanding how applying one particular stress in a selection system improves tolerance to one or more unrelated stresses is an aspect that deserves proper research.
