Abstract

In field pea (Pisum sativum) crops worldwide, sowing seed with minimal Pea seed-borne mosaic virus (PSbMV) infection is crucial to manage its spread and the seed yield and quality losses it causes. The possibility of using seed fractionation to help decrease PSbMV infection in infected seed-stocks used for sowing crops was investigated. When six PSbMV-infected seed-lots of Australian field pea cvs Kaspa or PBA Twilight were passed through sieves of different mesh sizes to obtain different size fractions, PSbMV seed transmission rates to seedlings were significantly higher in the <6.5 mm than the >6.5 mm fractions. Passing pea seed-lots through a 6.5 mm sieve can be used to: (i) provide a useful indicator warning of likely high seed infection levels, and (ii) contribute towards decreasing PSbMV infection levels below the % seed transmission risk threshold for sowing.
