  Acid tolerance of Austrodanthonia accessions was evaluated in two experiments. In the first, seeds of the 183 Austrodanthonia accessions from 15 species, two Austrodanthonia cultivars (Taranna and Bunderra) and three exotic grasses, were sown in pots containing a sandy loam soil at pHCa 3.9, 4.4 and 5.3. Seedling emergence and survival were recorded at 44 and 170 Days After Sowing (DAS) and Dry Weight (DW) at 186 DAS. In the second experiment, seedlings of 20 of the Austrodanthonia accessions and cvs used in experiment 1 were planted into a brown chromosol/brown kurosol soil located near Carcoar, New South Wales (33°37’S, 149°13’E, elevation 820 m), into areas with natural pHCa values of 4.3 or 4.9. Plant growth was monitored over 16 months. Half the planting area was pre-sprayed with glyphosate to kill the resident pasture. In experiment 1, the lowest pHCa value (3.9) severely decreased emergence, survival and DW. In experiment 2, the pHCa value of 4.3 decreased survival and DW and there was an interaction with the herbicide pre-treatment. In both experiments, there were large differences between accessions in growth potential and acid tolerance. Relative acid tolerance rankings of accessions/cvs were similar in each experiment and DW seemed to be the most reliable index of acid tolerance. The diversity of acid tolerance and growth potential in Austrodanthonia may be useful in studying the genetics of Al tolerance and in plant breeding and selection.
