Sterility Mosaic Disease—the “Green Plague” of Pigeonpea: Advances in Understanding the Etiology, Transmission and Control of a Major Virus Disease
Abstract
This paper describes the pigeon pea sterility mosaic disease (SMD), provides an overview of the advances allowing the development of disease control strategies (including isolation, purification, and properties of the causal virus; diagnostics for the causal virus; determining the novelty in and relationships of the causal virus; transmission of the causal virus by the eriophyid mite vector; efficient screening methods for virus resistance; and variations in host plant resistance), discusses durable SMD resistance and disease management. Specific sections on the identification of broad-based SMD-resistant genotypes, mechanisms and inheritance of resistance to SMD, SMD epidemiology, and SMD management are presented, as well as future research prospects
