INTRODUCTIONSweet potato is an potential comodity for food,
feed, industry, and bioethanol raw materialTargeting sweetpotato
local varieties selection onto environmental change is the interest
of any plant-breeding program to matching yield production
AMMI biplot was simpler and informatif geometry for producing
graphical visualizations of patterns in yield-trial data, can
capture substantially more variation. AMMI biplot displays genotype
(G) main effects, environment (E) main effects, and genotype
environment (GE) interaction eff ects of interest to crop
scientists and soil scientists would need another biplot
METHOD
Study of genotype x environment interactions and to obtain local
varieties widely adapted or adapted to specific environment
conducted at Kebun Percobaan Fakultas Pertanian Universitas
Padjadjaran. Period of research in January 2011 - June 2011, July
2011 - December 2011, April 2012 - September 2012, July 2012 -
December 2012, and September 2012 February 2013
A randomized complete block design with two replicates over five
times planting were employed with 33 local varieties as treatments.
Combined of Anova integrated with AMMI was applied to detect the
genotype x environment interaction, to estimated genetic parameter,
and determine adaptation and yield stability.

Tuber yield stable over planting 2011 2013 : Variety Menes 01,
Nirkum 13, and Nirkum 27
CONCLUSIONYield of local varieties of sweet potatoes is
influenced by genotype x environment interactionsThere are three
local varieties that have a phenotypicaly stable in tuber yield,
i.e. variety Menes 01, Nirkum13, and Nirkum27
