Identifying Hybrids The Case of Neotyphodium lolii x Epichloe typhina... 

Perennial ryegrass (Lolium perenne) forms similar associations with Neotyphodium lolii or, more rarely, a second species of Neotyphodium classified as LpTG-2 [for L. perenne endophyte taxonomic grouping 2 (Christensen et al., 1993)] and exemplified by the isolate Lpl. LpTG-2 is a hybrid of N. lolii X Epichloe typhina (Schardl et al., 1994), and plants with this hybrid differ in their alkaloid profiles from those with N. lolii (Christensen et al., 1993 Bony et al.,...
