One virulent and three avirulent potato virus X strains were characterized qualitatively and quantitatively by the reactions of Gomphrena globosa and Capsicum frutescens. Spontaneous virulent mutants arose from time to time in the avirulent strains c

A number of lines of Macroptilium atropurpureum, including cv. Siratro, were grown in two experiments at different manganese levels in sand culture. In one experiment 40 ppm manganese was used in conjunction with nitrogen either in inorganic form or

The comparative effects of CaCO3 on growth, nodulation and chemical composition were determined in four Leucaena leucocephala lines (three bred), Macroptilium lathyroides and Lotononis bainesii grown in pots of an acid soil. Calcium carbonate treatme

Improvement over cv. Siratro in five advanced lines from an M. atropurpureum breeding programme was evaluated at four sites (with two soil-types at one site) during four growing seasons. On all except four of the 20 environment/season occasions all t

A method is described for evaluating persistence and productivity of pasture species in the advanced stage of testing. Six bred lines of Macroptilium atropurpureum were compared with cv. Siratro at Samford, south-east Queensland, under stocking rates

A detailed field trial and other experiments were made to explore the effects of leaf roll on the growth of different varieties of potato. The shoots of a tolerant variety, Up to Date, were little changed in size by infection at emergence, but during

A number of varieties of subterranean clover (Trifolium subterraneum L.) were tested with a severe strain of Phaseolus virus 2 Pierce. Northam First Early, Dwalganup, and Pink Flowered gave lethal necrotic reactions while the rest developed mottles a

A modified technique which has facilitated the detection of phloem necrosis in leaf-roll-infected potato plants is described. Placed on a quantitative basis, the necrotic reaction has proved valuable in the estimation of leaf-roll severity in varieti

Spotted-wilt-resistant and susceptible phenotypes among potato varieties and hybrids are not determined satisfactorily by hand-inoculation of leaves, but can be selected by stem-tip inoculation of vigorously growing plants at the flowering stage with

A virus of legumes causing a disease described as "little leaf" has infected with differing degrees of severity some 40 per cent. of pasture legumes in experimental plots in subtropical Queensland. The symptoms are similar to those caused by the "big
