Abstract

The relationship of peanut mottle virus to peanut production.

Abstract

This general paper on the peanut mottle virus, which is endemic in groundnuts in Georgia, contains a section on epidemiology. Some infected plants produce seeds, of which about 2% (usually the smallest) produce diseased plants, and it is believed that aphids carry the virus from seed-infected to healthy plants. Aphis craccivora Koch and Myzus persicae (Sulz.), which were collected from groundnut fields in Georgia, were both found to be efficient vectors of the virus during greenhouse tests. Other aphid species known as vectors of this virus elsewhere are enumerated [see RAE/A 59, 1311].<new para>ADDITIONAL ABSTRACT:<new para>Data are presented on yield losses of various cultivars of groundnuts due to infection with peanut mottle virus in field or glasshouse conditions. It was estimated that infection led to a mean yield loss of 20%/plant in Georgia in 1973.
