Stress tolerant, problems-specific

Early attempts to evaluate the genetic basis of stress tolerance in plants were restricted to simple genetic models. However, with the development of molecular markers, evaluating the inheritance of salinity tolerance became a more tractable problem since specific QTLs could be identified. Through the development of molecular markers, it has become possible not only to determine the genetic basis of the trait, but also to map specific chromosomal segments or QTL and to determine the relative contribution of each QTL to...
