Fast classification system for drought tolerance in peanut and soybean

Abstract

Drought is one of the major limitations for agriculture. The direct selection of tolerant genotypes on the fields is time consuming due to the unpredictability of the environmental conditions. Our group use a physiological approach to classify the genotypes under controlled drought at vegetative stage. We analyze several biochemical and physiological traits to classify the genotypes under stress, such as leaf relative water content (RWC) chlorophylls, and proline. The aims are to develop strategies to reduce breeding times for legumes and to identify soybean and peanut drought tolerant candidates for breeding.
