Drought resilient breeding in vegetable crops; a review

One of the most important constraint for agriculture is drought or moisture stress. Most recently global warming may be worsening this situation. Vegetables are more sensitive to drought as compare to many other crops. Improving yield under drought is a major goal of plant breeding. Responses of different genotypes to water deficit condition have been studied for a long time, and several morphological, physiological and biochemical characters have been suggested to be responsible for drought tolerance in vegetables. An attempt has been made in this review to compile the informations on concepts, genetics, various mechanisms and breeding approaches carried out by breeders in order to obtain varieties with improved drought tolerance.
