“…But according to our observation sugarcane calli can survive at 0.5mM Pb(NO 3 ) 2 in case of CP-77-400 and NSG-59 but could not withstand 1mM concentration of Pb(NO 3 ) 2 while calli of YT-53 were survived at this level. Surviving ability and regeneration rate of sugarcane calli under abiotic stress depend upon genotypes (Mahmud et al, 2021).…”

Heavy metal accumulation in agriculture land is one of the major agriculture challenges affecting the crop production and threatens the food safety. Comparative study for Lead (Pb) tolerance in three sugarcane (Saccharum officinarum L.) genotypes was carried out under in vitro conditions. Fresh weight, dry weight, callus morphology, shoot morphology, protein contents, catalase, superoxide dismutase and peroxidase, ascorbic acid contents, relative growth rate, stress tolerance index, Pb contents, bioconcentration factor were compared at 6 different concentrations of Pb (0mM, 0.1, 0.2, 0.3, 0.4, 0.5, 1mM). Lead affected the callus and its regeneration in all three genotypes while root regeneration did not affect considerably. All genotypes significantly vary at each treatment and parameter except BCF and protein contents. Genotype YT-53 proved most resistant toward Pb stress while CP-77400 was next to it and NSG-59 showed least resistance toward Pb stress. Most resistant genotypes can be used in heavy metal effected area for better yield and phytoremediation in Pb affected soil and in other breeding programs.

“…In Bangladesh, the average yield of high-yielding rainfed lowland rice is 3.4 t ha -1 , while aromatic rice yields 2.0-2.3 t ha -1 [14] In global context, salinity is a broad phrase that refers to the presence of high quantities of salts in soil and water, such as sodium chloride, magnesium and calcium sulphates, and bicarbonates with over 830 million hectares (ha) of salt-affected lands [15,16,17]. Salt stress is one of the abiotic limitations that causes significant yield losses [11,18,19]. Because of global climate change, soil salinity has arisen as a severe threat to food security [20].…”

Salinity is abiotic stress, which causes adverse environmental conditions for rice cultivation. In particular, local aromatic rice cultivation is heavily influenced by soil salinity stress, which has an impact on global food security. This study aimed to screen local aromatic rice genotypes in a hydroponics experiment using Yoshida solutions to evaluate the effect of increasing NaCl concentrations on the early growth stages of rice seedlings. Genetic diversity along with phylogenetic relationship was assessed using the random amplified polymorphic DNA (RAPD) markers. Out of 20 RAPD markers, 17 markers produced reproducible polymorphic bands. Individuals of all genotypes shared 88 (89.80%) of the 98 total RAPD elements amplified. The genetic distance-focused similarity index ranged from 0.05 to 0.94. The highest genetic distance (0.94) was discovered between genotypes Nayanmoni and Kalijira Barisal, and the lowest was between Badshabhog and Kataribhog (0.05). In addition, the OPS 3(510bp) and OPA 14(1100bp) markers could be used to identify salt-tolerant genotypes. According to genetic distance, the salt stress tolerant check genotype, Pokkali was genetically related to Chinigura as well as Kalijira Barisal. This study established a simple and consistent method for evaluating variability across various aromatic rice genotypes, which will benefit in genotype selection for breeding salinity stress tolerant aromatic rice varieties in Bangladesh.
