Abstract: (464 Views)
Due to the expansion of saline soils in recent years, identification of promising wheat genotypes with acceptable yield in saline condition is of particular importance. The present research was carried out in a randomized complete block design with three replications, in saline soil and water condition of Zarindasht region of Fars province during the growing seasons of 2017-2018 and 2018-2019. Experimental treatments were 15 wheat cultivars and lines including Sistan, Narin, Brat, Sarang, Mehrgan, Shoosh, Sahar, Aineh, Ms-90-15, Ms-92-8, Ms-93-5, Ms-93-6, Ms-93-14, Ms-93-16 and S-94-12. The results showed that the lowest sodium content, ion leakage and malondialdehyde of leaves was observed in Mehrgan and Sarang cultivars. Also, in the first and second year the potassium content and relative water content of leaves showed a significant increase in Sistan, Mehrgan, Brat, Sarang and S-94-12 compared to other genotypes. The highest number of days to maturity with a significant difference compared to other genotypes was observed in MS-93-6 and MS-92-8 lines. On the other hand, Mehrgan and Aineh cultivars were the earliest genotypes. Based on the results of the two-year test, four genotypes of Sarang, Mehrgan, S-94-12 and Brat had the highest yield, suitable earliness and proper yield components. In biplot analysis, these genotypes had the highest amount of grain yield and yield components. Based on the cluster analysis which was done by considering all traits, the genotypes were divided into three separate groups and Mehrgan, Sarang and S-94-12 genotypes were categorized in one group. These genotypes are recommended as salinity tolerant genotypes for planting in the study area.
