Catalogue: Ground Cover
Of the three rust diseases affecting wheat crops, leaf rust is often overlooked because it is thought to be less damaging than stem rust and stripe rust... The new pathotype found in WA last year has a DNA fingerprint identical to isolates of the '76 group' from eastern Australia, clearly showing it has spread from east to west in Australia... Some wheat varieties, such as King Rock , Fortune and Zippy , have additional leaf rust resistance that is expected to remain effective, meaning a lesser shift in their resistance ratings from moderately resistant (MR) to MS. LongReach Cobra , Mace and Carnamah varieties have shown varying responses to the new pathotype, so further tests are underway to more accurately determine how they might react...

Catalogue: GRDC Final Reports
Screening of rust resistance in key stages of the breeding program (parent evaluation, segregating and fixed breeding lines) has integrated rust resistant lines into all stages of the breeding process... Important factors in production risk addressed in this project were susceptibility to rust diseases (stem, stripe and leaf rusts) and intolerance of pre-harvest sprouting... Sustained routine evaluation of rust resistance in key stages of the breeding program including parent evaluation, early (segregating) and late (fixed) breeding lines, including both field and glasshouse screening approaches...
