Abstract

The stability analysis of variance for six rice genotypes, tested across environments, indicated that the genetic
differencesamongricegenotypesweresignificantat5%levelofprobability. Genotypesxlocationinteractionwasnon-
significant. The regression coefficients (b) and small deviations from regression (82)of the genotypes Pak-4554 and
Basmati-385 were found to be non-significant. The latter was significant for all genotypes except Pak-4554 and
Basmati-385.Basmati-385performed almostbetteratalllocations.Therefore,theidealricegenotypewasBasmati-385
which showed average stableresults.
