Abstract
Salinity is an important abiotic stress limiting alfalfa "Medicago sativa, L." production. Thus, finding out genotypes have high salt tolerance with high germination, early season growth and productivity became an urgent need. Commonly, counting of germination after seven days from sowing, that, reflected emergence of seedling, was clearly distinguishing salt- tolerant population as Makka, Rammah1, Nubaria1, and Sohage, in all studied four salinity gradients. Also, counting after 21 days which indicates establishment, supported the former findings with additional prove of law salinity tolerance of Pakistani population. Sohage and Egaseed cultivars, scored about 70 cm of plant height under low salinity level (4.0ds/m) and both of Italian and Australian cultivars, gave as low as about 45 cm of plant height under the high level of salinity (10.50 ds/m). Sohage, Siwa 1 and Nubaria 1, significantly exhibited the heaviest stem weight (5.37, 5.34 and 5.29 g/stem, respectively). While the least significant stem dry weight was recorded by any of Australian and Italian cultivars (4.34 and 3.32 g/ stem, respectively). Makka cultivar significantly maintained superiority in root dry weight (9.12 g. plant-1), followed by Sohage cultivar (8.66 g. plant-1). The highest plant dry weight was obtained from any of Siwa 2, Frafra, and Sohage cultivars, when sown in 4.0 ds/m salinity level (1.05, 1.15 and 1.14 g. plant -1, respectively). The least plant dry weight was recorded by Italian cultivar sown in salinity of 10.5 ds/m (0.57 g. plant -1).
