Abstract

Multilocation yield trials on fifteen early duration (90-105 days) finger millet (Eleusine coracana
G.) genotypes were conducted under early and late transplanting condition at Bhubaneswar and
early direct sown condition at Berhampur for three years 2004-2006, during kharif season. G´E
interaction analysis in Eberhart and Russell model revealed highly significant differences among
genotypes and environments. The G´E interaction component was also significant indicating
differential performance of genotypes over environments. Considering mean, regression and
deviation from regression together VL 149 showed stability and adaptability to all environments,
while OEB 65, RAU 8, BM 107-2 and DM 7 showed specific adaptation to favourable environments
and Neelachal showed specific adaptation to unfavourable environments.
