Improving salinity tolerance in rice using
Each data point represents the mean value of three biological replications. It is also believed to be the causal gene in Saltol QTL region which accounts important aspect of seedling salt tolerance Bonilla et al.
The lowest MDA level was obtained for O. Water levels were monitored and adjusted daily by the Scanalyzer 3D weighing and watering system LemnaTec GmbH, Aachen, Germanywith pot weight before and after watering being recorded.
List of salt tolerant rice variety
While the highest reductions of both shoot length The impact of salinity will be further exacerbated by factors such as marine inundation Takagi et al. These PCR results indicate that the nucleotide variations are very high in intronic regions compared to exonic regions between the cultivated and wild rice species. Discussion Currently limited salt-tolerant genotypes are available in the cultivated species of O. Water levels were monitored and adjusted daily by the Scanalyzer 3D weighing and watering system LemnaTec GmbH, Aachen, Germany , with pot weight before and after watering being recorded. The susceptible checks IR and IR29 showed dramatic growth inhibition by salt stress Similarly, the daily water loss from each pot was obtained by subtracting the weight before watering in the current imaging day from the weight after watering on the previous imaging day. In each experiment, eight plants per entry were scored. Phenotyping of physiological traits Gas exchange values Plants were phenotyped throughout the experiment for growth parameters. Pokkali grew significantly faster than the other genotypes. To develop a climate resilient agriculture for sustainable rice production, time has come to go back to the wild progenitors to capture the untapped traits and improve rice breeding with exotic genes.
Differences in vigor among rice cultivars accounted for much of the variation in survival under high salinity.
Shoot part is mostly affected in salt stress than the root. Samples were diluted 10 times after the extracted tissues were cooled at room temperature. The activity of a vacuolar antiporter was found to increase salt tolerance Fukuda et al.
