Abstract

Sixteen medium duration groundnut cultures were evaluated for pod 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 01249 was classified as highly stable genotype over three environments because of its high mean pod yield, with a regression coefficient close to unity and non-significant deviation from linearity.
