Genotype x Environment interaction for kernel yield in groundnut (Arachis hypogaea L.)

Sixteen medium duration groundnut cultures were evaluated for kernel yield, stability and adaptation across four environments. The G X E interaction was highly significant and both linear and non-linear component are equally important for yield stability. The genotype ICGV 92004 was classified as highly stable genotype over four environments because of its high mean kernel yield, with a regression coefficient close to unity and non-significant deviation from linearity.
