Description
The snow mould fungi (Fusarium nivale, Typhula incamata and T. ishikariensis) are limiting grass production in cool temperate areas. A programme was initiated to improve the resistance to snow mould in perennial ryegrass (Lolium perenne) and meadow fescue (Festuca pratensis). Hardening and artificial inoculation were performed in controlled environment chambers. A single strain isolate of pink snow mould (Fusarium nivale) was more aggressive in meadow fescue than a mixture of isolates.
he progenies from surviving plants after one test were used for the next cycle of selection. After one cycle of selection in meadow fescue a moderate improvement and after three cycles in perennial ryegrass a very considerable improvement was recorded. These results are taken as an example of what can be achieved with recurrent mass selection, a method which is very effective when the heritability is reasonably high and when an effective screening technique is available.
