Salt Responses of Four Cotton Genotypes Grown in Two Soils

Significant research has been devoted to cotton salinity tolerance screening, but there is an abridgement of research evaluating cotton salinity-plant-soil relations in salinity screening. Furthermore, the literature base concerning the efficacy of any singular phenotypic salinity-tolerance screening method; as the individual methods are irrespective of the varying physiological mechanisms and responses at different plant life stages, is limited.  Accordingly, this necessitates a better understanding to bridge the gap between in vivo experimentation to existing agronomic practices. This study evaluated the effects in salt tolerance due to genotype, salt treatment, soil, and interaction from genotype by salt treatment, genotype by soil, and genotype by salt treatment by soil in three seedling growth stages based on four selected advanced back cross inbred lines (BIL) derived from a cross between Upland and Pima and two soil types. Plant height, biomass, nutrients and other physiological traits will be determined.
