Abstract
Genotype-environment interactions through different stability parameters and performance traits of four fine rice
genotypes were studied. The traits were; days to 50% flowering, days to maturity, plant height (cm), number of
effective tillers per hill, panicle length (cm), number of fertile grains per panicle, number of sterile grains per panicle
and yield (t/ha) in four fine rice genotypes across nine environments along with experimental farm of Genetics and
Plant Breeding department, Bangladesh Agricultural University (BAU) Mymensingh. Significant differences were
observed for genotypes, environments and genotypes–environment interaction. Stability analysis after Eberhat and
Russell’s model suggested that the genotypes used in study were more or less responsive to environmental changes.
Most of the genotypes performed better in Comilla. BAU125 was found stable for effective tillers per hill and
comparatively less sensitive to other genotypes in panicle length and number of sterile grains per panicle. BR5 was
stable for days to maturity and plant height whereas Kalizira performed better than other genotypes for fertile grains
per panicle. In general, only the genotype BAU125 was found stable for effective tillers per hill, panicle length and
lowest number of sterile grains per panicle.
