CORRELATION AND PATH ANALYSIS OF YIELD AND YIELD COMPONENTS IN DEEP WATER RICE (ORYZA SATIVA L.)

Published on

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.
