PLANT VARIETIES JOURNAL 1997 VOL 10 NO. 2 Comparative Trial Comparators: three other ecotype populations (‘Shepherd’s Lookout, ACT’ – collected by R H Groves and MJ Kilby, CSIRO Canberra ACT; ‘Bawley Point, NSW’ – collected by M Kilby; ‘Douglas Park, NSW’ – collected by BM Sindel and MJ Kilby) of the same species collected over a transect from the South coast, NSW to the Monaro, NSW – a transect that covers some of the variation known in the species which occurs naturally over the entire Australian and African continents. Location: Canberra, ACT Sep 1995 – May 1996. Conditions: Table 23 Themeda varieties seedlings raised in 20 cm diameter pots containing 75% potting mix, 25% sand, watered daily and complete fertiliser tablets added regularly. Trial design: randomised Latin Square design. Measurements from 100 plants of each of two generations. Prior Applications and Sales Nil.
