Evaluation Capability of Wheat (Triticum aestivum L.) Genotypes under Salinity (NaCl) Stress as a Sy

Healthy seed germination is essential for plant growth, since it determines seedling establishment and subsequent crop yield. High saline conditions can make seed germination difficult and prolong the germination period. One significant technique for overcoming this problem is to develop salinity tolerant genotypes through screening and selection. Salinity (0 mM NaCl (distilled water)), 50 mM NaCl (low salt stress), and 100, 150, and 200 mM NaCl (high salt stress) all had progressive and unfavourable effects on seed water uptake and germination properties in the current investigation. The findings revealed a wide range of genetic materials' ability to withstand salt. Overall, among 14 wheat genotypes, (Sids-12, Nielien, and Weiber) genotypes appeared to be relatively salt tolerant, while (Gimeza-12, Diebera, Misr-1, Katela) genotypes appeared to be moderately salt tolerant genotypes, which were attributed to higher germination percentage, seedling length, seedling fresh and dry weight, tissue water content, vigour index, and tolerance index. The genotypes (Shandaweil-1, Giza-168, Misr-2, Sids-1, Sanora, Gimez-7, and Sakha-94) on the other hand, were shown to be moderately to strongly sensitive to salt stress conditions. This approach can be used to find genetic diversity in salt tolerance in either breeding material or a large number of wheat genotypes, and it can also be used to account for variances in salinity tolerance.
