ten environments during 2015-16 growing season (rain-fed) of
Pakistan. To compare the various stability measures of both
parametric and non-parametric type and identify the stability and
adaptability of genotypes also evaluate association among them.
Combined ANOVA was applied with 2 replications in each
environment through NUWYT. The impacts of genotypes,
environments and GEI were found highly significant at (P<0.01).
Mean yield of genotypes had +ve and highly significant correlation
along with bi, Si
(3) and Si
(6) while had inverse and highly significant interrelationship with S2
i, NPi
(2)
, NPi
(3)
. Wricke’s Ecovalence and
Interaction variance, Superiority index and deviation mean square
had significant perfect association so therefore they can be used as
alternatives. Accordingly, most of the stability parameters among all
showed that G1 and G8 were the stable genotypes across environments. | | Keywords : | | | Parametric and non-parametric stability models,
