The phenotypic as well as genotypic correlation and path analysis of yield and yield
contributing characters were analysed in 3 sets (25 genotypes in each set) of deep water rice
(Ory:;a sativa L.). Grain yield had showed highly significant rp and r8 with PDT and grains
per panicle in all the 3 sets studied. Grain yield had highly significant rp and r8 with plant
height, panicle length in Set-III only where test weight was high. PDT had highest positive
direct effect on grain yield in all the three sets invariably with the difference in test weight.
In Set- II and Set-III where test weight was medium and high, grains per panicle showed
next highest direct effect towards grain yield. Direct effect of plant height was considerable
in Set-I only.
Keywords: Oryza sativa L., correlation, path analysis.
