摘要：

Two clones (R1 and R2) of perennial ryegrass selected from cv.S.23 pastures for immunity to a few isolates of ryegrass mosaic virus (RMV) retained immunity when inoculated manually with isolates from 10 widely‐separated sites in Britain and when grown outside at eight other sites for 1 yr. At a ninth site (Saxmundham) an isolate (RMV‐Sax) capable of infecting both resistant clones (although only with difficulty) was detected in one plot. Resistance to a Rothamsted isolate of RMV and to RMV/Sax was also shown by R1 × R2 progeny. Clone R1 yielded more than S.23 in small field plots as did R1 × R2 and R2 × R1 progeny in a pot experiment. Copyright © 1979, Wiley Blackwell. All rights reserved
