Review Salinity as a problem in agriculture: plant breeding an immediate solution
Main Article Content
Abstract
worldwide. This shows a tendency to increase in coming years
worldwide, as well as Cuban territory, where this environmental
phenomenon, regardless of weather conditions, has led to
processes of soil degradation, affecting crop yields of major
interest in the national economy. Salt stress, causes
physiological and biochemical changes in plant metabolism
that determine their survival and productivity in these
conditions, so plants have evolved mechanisms of tolerance.
Genetic improvement offers an increase in both the recovery
of underutilized areas, and yields in areas where salinity is a
limiting factor or for which you work in various ways. Given
that the selection of salt tolerant plants, is a long process
determinedly, working in the search for efficient indicators for
early selection of genotypes with better agronomic
performance. These aspects are addressed in this paper
focusing on the improvement as an effective tool for the
selection of genotypes of different crops with better
performance under salt stress.
