Abstract
The present investigation was conducted to identify promising and stable genotypes from 21 advanced breeding lines using Eberhart and Russell model and to compare the suitability and authenticity of the Eberhart and Russell model with various other stability models like Shuklas si2, Wrickes Wi2 and Tais λi. The analysis of variance for stability revealed highly significant differences between genotypes which suggested that the genotypes differed considerably with respect to yield performance.
The linear genotype × environment interaction as well as pooled deviation mean squares were also significant, indicating the presence of both predictable and non-predictable components.
Five genotypes LT31, BR231, BR233, BR242 and BR234 were identified as ideal and stable through Eberhart and Russell model and were also confirmed by other stability models.
It was concluded that Eberhart and Russell model can be reliably used for the identification of stable opium poppy genotypes over environments.
