The purpose of the research was to study the
adaptability and stability of corn genotypes on peat
soils. Seven genotypes of corn (Arjuna, Bisma,
Lamuru, Srikandi Kuning, Srikandi Putih, Maros
Sintetik-2, and Sukmaraga) were used to study the
genotype vs environment interaction. Peat selected
based on flood type which Rasau Jaya II ( type A),
and Rasau Jaya I (type B and C). The results
showed that genotypes Arjuna, Bisma, Lamuru,
Srikandi Kuning, and Sukmaraga were good
adapted for three environments. Srikandi Putih and
Maros Sintetik-2 were poorly adapted. Arjuna and
Lamuru were stabile genotype on all environments
type.
