Abstract
Sixty one genotypes were evaluated in randomized block design with three replications to study the correlation and path co-efficient analysis for ten quantitative characters in castor (Ricinus communis L.) under irrigated conditions during rabi seasons of 2014. Correlation studies revealed that seed yield was positive and significantly genotypic as well as phenotypic associated with leaf plant height up to primary spike, total length of primary spike, length of capsule bearing region of primary spike, number of effective branches per plant, number of capsules on primary spike and oil content. Path coefficient analysis showed that number of capsules on primary spike, number of effective branches per plant and oil content were the most important characters manifesting large direct effects on seed yield per plant. It is, therefore, suggested that simultaneous selection for total length of primary spike, length of capsule bearing region of primary spike, number of effective branches per plant, number of capsules on primary spike would result in improvement of seed yield by phenotypic selection in castor.
