Tolerance and Adaptability of Tomato Genotypes to Saline Irrigation

High salt concentration in irrigation water is often a limiting factor to tomato production Brazil. However, there limited information available regarding the tolerance of genotypes saline irrigation. An experiment was conducted protected environment using randomized block design with four replications. Treatments consisted 12 cultivated an varying levels stress. Moderate and severe stress affected plant height, transversal longitudinal diameter fruit, fresh mass, yield, number fruit per plant. Cluster analysis, stability, adaptability provided best estimates identify most adaptable genotype stress, Maestrina, Onix, Pizzadoro, Shanty being adapted moderate conditions. The were identified as stable under Sodium absorption increased salinity increased. In addition, P, K, Ca decreased which caused damage all yield components nutrition. Onix more tolerant effects irrigation, while Sheena, Sperare, Santa Clara, IPA 6, Dominador had lower losses
