A greenhouse research was conducted at the research area of Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad to evaluate 20 accessions for the identification of salt tolerant genotypes of sunflower (Helianthus annuus L.) as well as their characteristics. The experiment was conducted in completely randomized design with three repeats. Salinity was developed with NaCl to achieve the final levels of 3, 6 and 9 dsm-1 salinity, whereas control contained tap water. After 60 days of planting, 10 seedlings of each accession from each treatment and replication were uprooted and data was recorded. Sunflower genotypes G-36, G-61, A-23, A-61 and A-185 performed better in both controlled and saline conditions. These genotypes showed better shoot and root growth and biomass by least concentration of Na+ and higher concentration of Cl- in leaf sap.
Key words: Tap water, NaCl, replication, leaf sap.
