Field evaluation of transgenic white clover with AMV immunity and development of elite transgenic germplasm

Abstract

Viral diseases such as alfalfa mosaic virus (AMV) cause significant reductions in dry matter yield and persistency of white clover (Trifolium repens L.). Transgenic white clover plants expressing the AMV coat protein (AMV-CP) gene and showing immunity to AMV infection were evaluated in multi-site small-scale field releases. Two transformation events showing field immunity to aphid-mediated AMV infection This article outlines the development of transgenic elite white clover germplasm with AMV immunity, involving the world’s first breeding nursery for transgenic white clover.were selected for elite transgenic germplasm development. Following top crosses with elite parental breeding lines, dial..
