Sixteen cashew clones were evaluated for their nut number and nut weight on the bris soil environment at MARDI Sg. Baging for over 7 years (1977- 83). Highly significant clone x year interaction was observed indicating that yield performance of genotypes varied disproportionately over the years. C 1 1 and C 21 clones have the highest mean yields (1 535 and 1 144 nuts/tree per year respectively) but they were also less consistent over the years of study because of their high deviations from regression (s2d=0.57 and 0.55 respectively ) and larger egression coefficient ( b=23** and 2.37' ** respectively). The stability parameters were discussed.
