Abstract

Twelve cassava clones were tested at four locations from May 1993 to March 19940 using a randomized complete block design with three replications. Data on yield stability were analyzed by using the linear regression technique to evaluate clones adaptation and stability. The result showed that the highest yield was achieved in Simalungun followed by Sarko with the yield average 35.38 and 28.29 t/ha, respectively. The combined data analysis showed that the effect of environment and genotype x environment interaction were significant. The clones Adira II/HT-14 and G 10 showed specific adaptability to highly and low productive environments, respectively.
