  In this paper, we dualize the concept of {\Sigma}-Rickart modules as
{\Sigma}-dual Rickart modules. An R-module M is said to be {\Sigma}-dual
Rickart if the direct sum of arbitrary copies of M is dual Rickart. We prove
that each cohereditary module over the Noetherian ring is a {\Sigma}-dual
Rickart. We introduce the notion of strongly cogenerated modules and
characterize {\Sigma}-dual Rickart modules in terms of strongly cogenerated
modules. We also study some properties of {\Sigma}- dual Rickart modules and
find connections with semisimple Artinian ring, regular ring semi-hereditary
ring and FP-injective module. Further, we study the endomorphism ring of
{\Sigma}-dual Rickart modules
