The aim of this work wasto conduct varietaltests targeting to determine the best adapted varieties. These tests were carried out in the lowlands of Boli and KeurAliou Gaye, Senegal. During those seven years, the number of rainy consecutive days does not exceed five which show of the arid climate. In 2003, in KeurAliouGueye, varieties "WAS 63-22-1-1-3-3" (5.4 t/ha) and "WAS 164-B-5-2" (5.7 t/ha) exceeded the control over 2 tons. In 2005, all varieties reached a cycle shorter than 100 days, which shows adaptability in these environments. Four out of the ten varieties that has been tested in Boli, have produced above the average yields of the test: "WAS 57-BB-17-3-3-5" (6400 kg / ha),"WAS 63-22-5-9-10 -1" (5578 kg/ha), "WAS 127-B-5-2" (5230 kg/ha) and "WAS 63-22-1-1-3-3" (4663 kg/ha). Use of this batch of tested varieties is an essential component in the development of an integrated management strategy of rice in the region.
