The attainment of new genotypes adapted to the climate conditions and soil of each environment contributes in a decisive way to the success of the cashew agribusiness in Brazil. This work aimed to select new dwarf cashew clones for the conditions of Aracati County, Ceara State. The experimental phase has been conducted in a grower area using 15 clones in a randomized block design with four replications, four plants per plot spaced 8 m x 6 m. The traits plant height, canopy diameter and nut production were evaluated. The results obtained from 2000 to 2003 showed that 10 clones (66% of the total) in the first year, 8 clones in the second year and 14 clones in the third year did not differ from the CCP 76 (control clone). For both plant and kernel technological traits PRO 555/1 and CAPI 7 clones were considered the most promising materials. The estimated nut productivities of these clones were 620 kg.ha -1 and 501 kg.ha -1 , respectively, in the second harvest.
