Soil salinity is one of the major constraints to rice production and constitutes a real challenge for the State of Senegal to meet the population's rice consumption needs and to achieve food self-sufficiency. Thus, a subject was made available to us whose objective of the study is to evaluate the agro-morphological performances of thirteen (13) new varieties of rice tolerant to the salinity under the conditions of culture of the delta of the valley of the Senegal River. The trial was carried out at Ndiol's Serigne Moustapha Bassirou MBACKE station under salt stress conditions of five decis siemens per meter (5ds / m) during the hot off-season with sowing in mid-March. The experimental device chosen was of the "Apha-Lattice" type or incomplete block device with 3 repetitions. Saline stress as well as agro-morphological characteristics such as the number of days at 50% heading, the number of days of sowing at physiological maturity, the number of tillers at harvest, the number of panicules per m2 and the yield have have been analyzed. Agronomically, the analysis of variance reveals that there is a significant difference in the studied traits of yield components with the exception of the weight of 1000 grains and the yield at 14% moisture. However, the two varieties HHZSALT 10, D33-NDIOL-3-LON-1 and the FL 478 tolerant control gave the best yields with respectively 3.532, 3.064 and 3.607T/ha.
