There are certain critical traits that help us to determine drought-sesitive or drought-tolerant genotypes? This question seeks information on these useful traits
Drought and/ or salt tolerance are quantitative traits, so we need to have several traits in our selected or chosen tolerant genotype. There are many many papers published on this topic, but no single trait was correct for all crops.Cheers.
At times, with the same genotypes of the same species we can reach different conclusions, when using different drought-imposed methodologies under different set of environmental conditions
Being legume the root traits may respond to the applied stress differently. But for the whole plant other growth indices and leaf functional trails that are generally used to monitor drought stress can be used like LMA/ SLA, LTD, LDMC etc.
