e0“The present study reports use of relative water content (RWC), membrane stability index (MSI), DAB (Diaminobenzidine) assay and yield parameters for screening drought tolerance in common bean”
e1“The lines showing greater per cent reductions in yield parameters show greater staining in DAB assay underlining the reliability of using this assay as a reliable supplement to phenotyping protocols for characterising large germplasm sets”

- Observation Genotype WB-451 showed the lowest relative water content decrease (2.97%) under drought.
- Observation Membrane stability index under water stress was lowest in SR-1 (0.113).
- Observation Membrane stability index under water stress was 0.189 in WB-257 and 0.220 in WB-185, the next lowest values.
- Observation Membrane stability index under water stress was highest in WB-83 (0.814).
- Observation Membrane stability index was 0.751 in WB-401 and 0.735 in WB-341, the next highest values.
- Association Genotypes with better yield performance had better membrane stability index under stress.
- Observation Genotype SR-1 showed the largest pod length reduction (44.52%) under water stress.
- Observation Genotype WB-1587 showed a pod length reduction of 26.34%, followed by WB-83.
- Observation Genotype WB-341 showed the smallest pod length reduction (8.96%).
- Observation Genotypes WB-6 and Arka Anoop had the largest seed weight reductions, 18.93% for WB-6 and 17.45% for Arka Anoop.
- Observation Genotype WB-1634 showed the lowest seed weight reduction (5.74%).
- Observation Genotype WB-6 showed the largest seed yield reduction under drought (55.09%).
- Observation Genotype WB-1492 showed the second largest seed yield reduction under drought (51.86%).
- Observation Genotype WB-1634 showed the lowest seed yield reduction under drought (11.33%).
- Observation The largest decrease under drought was in seed yield per plant, followed by pods per plant; 100-seed weight decreased least.
- Method / resource The DAB assay differentiated the lines by darker leaf staining under water stress.
- Association Lines with greater yield-parameter reductions showed greater staining in the DAB assay.
