Due to its tolerance to drought and ability to survive uncertain rainfall patterns, cassava is considered a contributor to food security against famine. Our work aims to identify traits that contribute to drought tolerance in cassava and could be utilized for phenotyping in breeding programs. Faurty five cassava lines representing a range of drought tolerance were assessed for their drought tolerance response. Water stress experiments were conducted in field conditions at CIAT in Colombia. Parameters evaluated included non-structural carbohydrate partitioning and remobilization, abscisic acid accumulation, leaf retention, relative water content, leaf canopy temperature, and root growth, among others. Results demonstrated that genotypes differed in their response to water-stress and well-watered conditions. Water stress depleted leaf carbohydrate, consistent with priority carbon utilization rather than use as an osmotic adjustment. Timing of ABA accumulation differed among plant organs. In addition, leaf and stem ABA was negatively correlated with stem and leaf carbohydrate accumulations. Leaf retention was mild in WW treatments (60-80%) and severe in WS treatments (20-40%). All genotypes maintained high RWC (>90%) with litter or no variability in both WW and WS treatments. The diverse drought stress responses and parameters evaluated within genotypes suggest high genotypic variability and potential usage of specific phenotyping schemes. |
