Seasonal variation in yield performance of 16 cashew clones on bris soil

Abstract

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.
