Some of the identified genotypes by the plant physiology division have already been released as stress-tolerant variety (salinity tolerant mustard BARI Sarisha-19, waterlog tolerant sesame BARI Til-6, and drought tolerant BARI Hybrid Maize-12 and BARI Hybrid Maize-13) from respective crop centers or divisions of BARI. Some of their important features are mentioned below:

Selection of Salt Tolerant Rapeseed/Mustard Genotype for Coastal Areas of Bangladesh

Jun-536 (BARI Sarisha-19) was selected as salt tolerant genotype.

Key features of selected genotypes

• Less uptake of Na⁺ ion with higher K⁺/Na⁺ ratio
• Produced higher amount of ROS scavenging enzymes like CAT and POD
• Produce less amount of MDA
• Less affected in leaf area, photosynthesis, TDM, and seed yield

Selection of waterlogging Tolerant sesame genotype

Findings

Ses MR-20 (BARI Til-6) can tolerate 72 hours of waterlogging at the vegetative stage.

Key features of tolerant genotypes

• Less visible of leaf chlorosis
• Perform the best ranks mean and low standard deviation of ranks in consideration of all indices
• Survived from waterlogging injury with the higher Pn, Gs, Tr and photosynthetic pigments
• Less affected in TDM and seed yield production
• Less accumulation of ROS (H₂O₂ and O₂^-), MG, and MDA
• Maintained higher antioxidants like POD, APX, GPX, ASA, and Proline
• Higher activity of the ADH and PDC including the lower activity of LHD
• Formation of aerenchymatous tissues in roots
• Alcoholic fermentation occurs to provide a source of energy
