“…In our study, all markers generated polymorphic banding patterns where a total of 53 alleles were detected across the genotypes with an average of 4 alleles per locus which was compatible with the previous work of Ali et al, (2004). The number of alleles detected is one of the selection categories in assessing a marker's usefulness in diversity analyses since a higher allele count per locus means that the marker is able to discriminate genotypes that might be indistinguishable to other markers (Khanam et al, 2018). In our study gene diversity at each SSR locus was significantly correlated with the number of alleles detected, number of repeat motif and with the allele size range.…”

Salinity is one of the major abiotic stresses which severely affect the production of crops across the world. In this experiment, we examined 20 rice genotypes of diverse origins and sources including few salt tolerant varieties (Binadhan-8, Binadhan-10, Pokkali and FL478) as check. The main objective of this study was to determine salt tolerance at seedling stage and to evaluate genetic variation using SSR markers. IRRI standard protocol was applied to screen out salinity among those varieties, at the glasshouse of Bangladesh Institute of Nuclear Agriculture, BAU campus, Mymensingh-2202. Shoot length, root length and total dry matter were recorded at 6dS/m, 8dS/m, 10dS/m and 12 dS/m salt stress levels. According to the morphological and molecular survey of 20 rice genotypes at the seedling stage it was evident that, Binadhan-8, Binadhan-10, Pokkali, FL478, IR64, IR4630, FR13A and Sadamota identified as salt tolerant whereas THDB, Moulata, MV-20, CPD-23, CPD-29, Pot-18, Pot-27 and Dudkalam those were found as susceptible, BRRI dhan67, Binadhan-17 and Binadhan-21 those were traced as highly susceptible. The highest Nei’s genetic distance value 1.0 was found in Moulata vs Sadamota and the lowest value 0.08 was observed in Binadhan-21 vs IR64. It will be used in future breeding program to develop a saline tolerant variety of rice. Res. Agric., Livest. Fish.8(1): 75-88, April 2021

“…However, when the plants were 8 weeks after planting, the plant height of three rice tested was higher when planted in non-saline compared grown in 8 dS m -1 . The decrease of plant height under 8 dS m -1 due to negative impact of salinity by inhibiting the photosynthesis rate, changes of enzyme activity, and decreasing of carbohydrate production [14]. According to the research of Alam et al salt concentration above 8.5 up to 12.5 dS m -1 caused a decrease of plant height in BR5828-11-1-4 rice cultivar up to 45% compared to the control [15].…”

Salinity caused losses to rice farmers because it becomes an obstacle to rice growth and decrease a productivity. The use of superior rice variety is an effort to rice produce optimally. In order to examined and compared several rice varieties to salinity stress based on agronomic, chlorophyll content, and yield characters. A factorial completely randomized design was used in this study, the first factor was rice varieties consisting of Banyuasin, Inpari 30, and Inpari 34, while the second factor was salt concentration consisted of non-saline and 8 dS m−1. There were six combination treatments and repeated three times. The results showed that Inpari 34 had a tallest plant compared to other varieties in non-saline and 8 dS m−1. Banyuasin and Inpari 30 had wider leaves, the number of panicles per clump, and higher harvest index compared to Inpari 34, however Inpari 34 produce more grain per panicle compared of two varieties. Inpari 30 grown in 8 dS m−1 had a highest chlorophyll a-b compared to the other treatment. Inpari 30 had the best agronomic performance indicated by increases of leaf area, number of panicles per clump, harvest index, and content of chlorophyll a-b.

“…It has been proven that 50 mM NaCl stress reduces plant height, tillering, leaf relative RWC, chlorophyll and yield ( Naim, 2014 ). Khanam et al (2018) and others also proved that 50 mM salt stress in pot experiments will have negative effects on the plant height, tiller number, leaf number and leaf area of rice. However, in the experiment of Hariadi et al (2015) , we found that 50 mM salt stress could not significantly inhibit the growth of some salt-tolerant varieties.…”

Salt stress affects crop quality and reduces crop yields, and growth regulators enhance salt tolerance of crop plants. In this report, we examined the effects of prohexadione-calcium (Pro-Ca) on improving rice (Oryza sativa L.) growth and tillering under salt stress. We found that NaCl stress inhibited the growth of two rice varieties and increased malondialdehyde (MDA) levels, electrolyte leakage, and the activities of the antioxidant enzymes. Foliar application of Pro-Ca reduced seedling height and increased stem base width and lodging resistance of rice. Further analyses showed that Pro-Ca application reduced MDA content, electrolyte leakage, and membrane damage in rice leaves under NaCl stress. Pro-Ca enhanced the net photosynthetic rate (Pn), stomatal conductance (Gs), and intercellular CO2 concentration (Ci) of rice seedlings, while increasing the activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbic acid peroxidase (APX) at the tillering stage under salt stress. Overall, Pro-Ca improves salt tolerance of rice seedlings at the tillering stage by enhancing lodging resistance, reducing membrane damages, and enhancing photosynthesis and antioxidant capacities of rice seedlings.
