Off-shore rust testing – barley stripe rust testing at CIMMYT 4

Off-shore rust testing – Ausvar (Grant Hollaway) CIMMYT 2011 AUSVAR set (92 lines incl. durum and trits) sent to CIMMYT, assessed for Yr (Sybil) and Septoria tritici (Andrew Milgate). Races: Pst RACE MEX96.11 and Mex08.13 Results are available on NVT website as part of the 2011 AUSVAR/NVT results New Zealand AUSVAR was going through quarantine during 2011, field testing during 2012. Ability to send Australian lines directly to New Zealand for field testing is unlikely due to the presence of high plains virus in Australia. United Kingdom Paul Fenwick (Limagrain UK) has offered to test AUSVAR set in the field, UK 2012. Feedback from the ACRCP CC - should we proceed with this, will the data be of value? 5
