“…These results can further be explained by biochemical parameters like ROS, MDA, MG, proline contents and LOX activity. Under abiotic stress like, salinity causes over production of ROS which interact with cellular organelles like protein, DNA, lipids and pigments to oxidation and functional loss, finally to cause cell death (Rohman et al, 2019). In this study, Genotypes like BD-10588, BD-6894 and IR-01 produced lower ROS like O2 •and H2O2 ( Fig.…”

“…This balance between the generation and scavenging of ROS is broken down by various biotic and abiotic stresses, including salinity drought. At higher concentrations, ROS are highly reactive and cause damage to proteins, DNA, lipids, and carbohydrates, resulting in cell death (Rohman et al, 2019). As a result, accumulation of ROS under environmental stresses is the foremost reason for reduced productivity of crops (Mittler, 2002;Apel and Hirt, 2004;Mahajan and Tuteja, 2005).…”

This study was conducted to obtain saline tolerant mungbean genotypes through evaluating growth, biochemical and molecular parameters, and possible salt tolerant mechanisms were studied in different salt sensitive genotypes. Thirteen prescreened mungbean genotypes were grown on 0, 40, 80 and 120 mMNaCl induced salinity and evaluated by germination percentage, shoot and root length, superoxide (O2•-) generation rate, concentration of H2O2, lipid peroxidation (as malondialdehyde, MDA), methylglyoxal (MG), K+/Na+ and proline content in leaves. Based on these parameters, genotypes BD-10588, BD-6894 and IR-01 were selected as tolerant genotypes. For studying oxidative stress tolerance mechanism, BD-10588 and IR-01 were used as tolerant and BD-6887 and BD-10741 as susceptible genotypes, and comparative ROS (O2•- and H2O2), and MDA as well as LOX activity between the two groups were determined. Analysis of activities of ROS metabolizing antioxidant enzymes strongly suggested that superoxide dismutase in tolerant genotypes provided first line protection from salt induced O2•-. Higher catalase (CAT) and ascorbate peroxidase (APX) played major role in H2O2 metabolism in tolerant genotypes. Both specific and in-gel activities of glutathione peroxidase (GPX) strongly proved the H2O2 metabolism for reducing oxidative damage in both tolerant and susceptible genotypes. However, higher peroxidase activity was important for mitigating salt stress in susceptible mungbean genotypes. Therefore, SOD, APX and GPX are very important for protecting salt mediated oxidative damage in mungbean genotype. Bangladesh J. Agril. Res. 44(3): 469-492, September 2019

“…Salinity is one of the major environmental constraints that severely limit crop production and productivity in many parts of Bangladesh (Rohman et al, 2019). In modern times, nearly 20% of arable land and 50% of irrigated land in the world are suffering from salt stress, which causes a great threat to agricultural production and surprisingly this area is still increasing (Yamaguchi and Blumwald, 2005;Rohman et al, 2019). In Bangladesh, more than 30% of the net cultivable land is in the coastal area.…”

A diallel cross was produced using diverse maize (Zea mays L.) germplasm of saline tolerant and saline susceptible maize lines as parents. Agronomic performance of the offspring of the diallel cross was examined. Eight germplasm lines bearing diversified agronomic traits of five known tolerant and susceptible lines were involved as parents of the diallel cross that was evaluated at three different ecological areas viz. Gazipur, Benerpota, and Kaliganj. CZ-29 and CZ-26 had positive and significant general combining ability (GCA) effects for yield in both the saline environments, where CZ-12 possessed negative and significant GCA effects for yield in the same areas but none of the parents exhibited either significantly positive or negative GCA in Gazipur location. Of the saline tolerant lines evaluated, CZ-29 was a good source for increased yield with significant and positive GCA values in both the saline environments that was also responsible for dwarfness and earliness in all locations. CZ-26×CZ-24 yielded well except at Benerpota with an additional benefit of shorter plant type across all environments. Hybrid CZ-29×BIL-65, however, was consistent and promising over the environments for bold seed and higher yield that ranked 2 nd at Benerpota (4.81 t ha -1 ) and Kaliganj (6.73 t ha -1 ) and 3 rd at Gazipur (7.40 t ha -1 ) location for yield having significant positive specific combining ability (SCA) effects at Gazipur and Kaliganj. Moreover, six hybrids either significantly or not consistently decreased yield over the locations with negative SCA. However, considering the overall performance of the hybrids, the involvement of saline susceptible or tolerant parents was not consistent in the present study. Crosses between saline tolerant lines did not produce any tolerant hybrids or dwarf parents did not produce dwarf hybrids except CZ-29×CZ-36 that was able to produce shorter hybrid for all the locations. Therefore, among the lines evaluated in this diallel cross having a distinct different genetic background, CZ-28 and CZ-29 contributed to earliness; CZ-29 and BIL-65 reduced plant height; CZ-12 increased seed size; CZ-26 and CZ-29 improved yield. Thus, these lines should be useful sources of alleles for pyramiding, earlier maturity, shorter plant heights, increased seed size and improved yield into desired breeding lines.
