AhmadRaza 122000312The response of ten different genotypes of Gossypium hirsutum to five NaCI concentrations i.e., 0, 50, 75, 100 and 150 mM were compared. Increasing levels of salinity caused significant reduction in fresh shoot weight and fresh root weight. On the basis of relative salt tolerance, cultivars CIM 435, CIM 1100, CIM 443, B 630 and FH 882 were found to be the most tolerant to salinity and B 622 and FVH 57 were moderately tolerant and B 496 and NIAB Krishma were susceptible to salinity. The estimates of broad-sense heritability of two plant characters ranged 0.75 to 0.98. The data suggest that improvement in NaCI tolerance in Upland cotton is possible by exploiting variMility through conventional breeding methods.]]>Allen, S.G., A.K. Dobrenz, M.H. Schonhorst and J.E.
