Six Setaria introductions were grown in small plots at three sites differing in soil type and location in south-eastern Queensland, and fertilizer and irrigation water were applied at similar rates. All plots of each introduction were genetically identical. Three different cutting regimes were imposed, such that at 12-week intervals during the 2 years of the experiment 4, 8, and 12-week regrowth was available for comparison of in vitro dry matter digestibility. There was an overall difference in digestibility between varieties of 6.6 percentage units, and the ranking order was usually the same for all sites, seasons, and ages of regrowth. Three of the introductions were consistently superior to cv. Nandi, the only commercial cultivar included in the present study. The two Setaria splendida introductions ranked second and sixth, although they were both higher in ash concentration than the other introductions, and this was associated with high potassium content. Differences between varieties in digestibility were not associated with flowering differences, despite large differences in flowering behaviour. The maximum mean difference between sites was 4.9 units and this was associated with differences in ash content. Difference in ash content, however, accounted for only 23% of the digestibility difference. The high ash content was associated with high concentrations of potassium. There was no association between nitrogen content and digestibility. The introduction lowest in digestibility had the highest nitrogen content. Digestibility was higher in winter than in summer at all sites, and the extent of this difference increased with age of regrowth. Higher digestibilities were obtained in younger regrowth.

Seedlings and older plants of 30 ecological races of Themeda australis were grown under controlled conditions to determine the effect of day length and vernalization on their flowering and on the incidence of apomixis. The races ranged in origin from latitude 6°S. in New Guinea to latitude 43°S, in Tasmania. One race from New Guinea and several from the Northern Territory behaved as strict short-day plants. The more southerly races, on the other hand, and several from north Queensland were long-day plants. In some, long days were required for both initiation and development of the inflorescence, in others apparently only for initiation. Some races required long days as seedlings, but not as older plants. Races from drier inland areas tended to be indifferent to day length in their flowering behaviour. At least four races from the colder areas responded to vernalization. Both the sexual and the aposporous reproductive pathways are described. Two races were wholly sexual in their breeding system and two appeared to be almost entirely aposporous, but most were versatile, displaying both sexual and aposporous reproductive behaviour. In seven races there was some evidence that day length influenced the reproductive pathway, short days causing increased apospory in all cases, regardless of the day length requirements for flowering.
