Vulnerability to fungal attack is a limitation for successful callus induction and germination in the culture room.

The leaf growth and Chlorophyll content has significantly shown to vary from the control ones while the grain yield was not affected. While many plant species naturally accumulate proline and protein as major organic osmolytes when subjected to different abiotic stresses. These compounds are thought to play adaptive roles in mediating osmotic adjustment and protecting sub cellular structures in stressed plants. Different approaches have been contemplated to increase the concentrations of proline like compounds in plants grown under stress conditions to increase their stress tolerance. Seven different traditional rice varieties of Assam were evaluated for their response to osmolyte production under physiological drought condition through simulation at three levels of osmotic stress of 0.15 bar, 0.25 bar and 0.56 bar of physiological drought initiated by polyethylene glycol (PEG 6000). Along with the evaluation for osmolyte response the different components of genotypic variation for six different drought-sustaining characters in the seven rice varieties were also substantiated. The results indicated that plant height and seed number have significant genotypic coefficient of variability (GCV) and heritability. Verities like Laodubi, Leserihali, Beriabhanga and Borah were screened out as the best drought sustaining variety.

Most of the agricultural field of Assam are flood prone that leads to a huge decrease in rice production and therefore, it is necessary to identify the submergence tolerant rice to be exploited for future rice breeding program. Six traditional rice cultivars selected from flood prone area of Assam, India were subjected to submerge stress for 7 and 14 days and their morpho-physiological, biochemical and antioxidant properties were analysed. Based on the overall analyses, Maguri, Nania and Kola Joha have been recorded as tolerant while Bora and Prasadbhog showed susceptible traits as compared to controls. However, in biochemical analysis, shoot and root showed significant differences in antioxidant activity. In case of shoots, Swarnasub1, Nania and Maguri exhibited the tolerance characteristics while Lachit along with Bora, Prasadbhog and Kola Joha were susceptible. On the other hand, root antioxidant analyses showed that Kola Joha was sharing tolerance trait with Swarnasub1 whereas, Prasadbhog and Bora appeared to be susceptible. From this investigation, we also evaluated the enzymatic and non enzymatic analyses under submergence stress with an aim to screen out the best cultivars that could be further utilized for developing submerged tolerant rice cultivar.
