Chlorotic Dwarf Virus (CpCDV) – Distribution, Symptomatology, Biology and Management in Chickpea (Cicer arietinum L.)

Abstract

Last three years, chickpea (Cicer arietinum L.) production was drastically reduced due to failure of flowering and pod formation by the new outbreak of chlorotic dwarf virus (CpCDV) incidence in chickpea. CpCDV is a monopartite ssDNA virus under genus of Mastrevirus with family of Geminiviridae with genome size of 2.8 kb. It has wide host range and distributed in global wide.  It produces chlorotic, yellowing or reddening small leaves with short internodes. Infected plants were showed bushy appearance only with ramification without flowering and podding stage. This virus consisted with 4 ORFs viz., V1 (capsid P), V2 (movement P), C1 and C2 (complementary) and comprised by ~ 39 kDa protein. Using practices like, proper time of sowing, maintain crop spacing and avoid pest population by chemicals were controlled the chlorotic stunt disease at possible.
