Not AvailableAn experiment was conducted during wet season of 2012 to study genetic variability, correlation
and path coefficient analysis in 31 diverse salt tolerant rice genotypes under coastal salinity
conditions of Goa. Analysis of variance showed highly significant differences among the tested
genotypes for all the characters studied. Phenotypic coefficient of variation (PCV) was higher
compared to that of genotypic coefficient of variation (GCV) in all the characters indicating the
influence of environment on the expression of these traits. High heritability coupled with high
genetic advance was observed for days to 50% flowering, length to breadth ratio, 100 grain
weight, straw yield per plot, harvest index and grain yield per plot indicating that these characters
are governed by additive gene action. Grain yield per plot showed positive and significant correlation
with panicle length, grain length, filled grains per panicle, spikelet fertility and straw yield per plot
and harvest index. Results of the path analysis indicated that grain length had maximum direct
effect on grain yield followed by harvest index and straw yield per plot. Such characters could be
utilized in selection for improving the grain yield under coastal salinity conditions.Not Availabl
