CORRELATION AND PATH CO-EFFICIENT ANALYSIS IN CASTOR (RICINUS COMMUNIS L.) OVER ENVIRONMENTS
to study the correlation and path co-efficient analysis for ten quantitative characters in castor
(Ricinus communis L.) under irrigated conditions during Kharif seasons of 2007-08 and 2008-
09. Correlation studies revealed that seed yield was positive and significantly genotypic as well
as phenotypic associated with leaf length, capsule length, length of primary spike and 100-seed
weight. Path co-efficient analysis showed that leaf length, length of primary spike, number of
nodes and days to 50 % flowering were the most important characters manifesting large direct
effects on seed yield per plant. It is, therefore, suggested that simultaneous selection for length
of primary spike and leaf length would result in improvement of seed yield by phenotypic selection
