2.  Sweet potato is an potential comodity for
food, feed, industry, and bioethanol raw
material
 Targeting sweetpotato local varieties
selection onto environmental change is the
interest of any plant-breeding program to
matching yield production

3.  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

4. 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.

9.  Yield of local varieties of sweet potatoes is
influenced by genotype x environment
interactions
 There are three local varieties that have a
phenotypicaly stable in tuber yield, i.e.
variety Menes 01, Nirkum13, and
Nirkum27
