The research has been conducted in WA wheatbelt to determine if new and existing varieties of barley vary in tolerance to commonly used herbicides... The sensitivity of the variety is summarised, using the following symbols based on the yield responses across all trials: not tested or insufficient data.. (z) no significant yield reductions at recommended rates or higher than recommended rates in (z) trials x% (w/z) narrow margin, % yield reductions at higher than recommended rate, but not tested at recommended rate significant event occurring w years out of z years tested...

Preliminary evaluation entries from previous years that have experienced narrow margin % yield reductions at higher than recommended rate are 'Advanced' to these trials for closer evaluation... The sensitivity of the variety compared to unsprayed controls of the same variety is summarised, using the following symbols based on the yield responses across all trials: not tested or only tested at higher than recommended rate (Please check Preliminary Evaluation tables) no significant yield reductions at higher than recommended rates in (Z) trials.. It must be emphasised that crop tolerance and yield responses to herbicides are strongly influenced by seasonal conditions...

The results for named cultivars are included in the following table but will be incorporated into the main table as more data becomes available... The sensitivity of the variety is summarised, using the following symbols based on the yield responses across all trials: no significant yield reductions at a higher than recommended rates in (x) trials but not screened at a recommended rate..

Wheat variety yields in 2011, across 25 South Australian NVT, were above average and ranged from 1.4t/ha at Wanbi to 6.6 t/ha at Cummins, with the trial at Penong failing due to variability from grass competition... This early maturing wheat, is susceptible to CCN but has moderate resistance to stem and stripe rust and is MS/S to leaf rust and MS to yellow spot... Seed is licensed to Pacific Seeds MaceA Mace (RAC 1372), released by AGT, is derived from Wyalkatchem, but has an AH classification taller plant height, is MR/MS to stem rust, MR to leaf rust and is rated..
