The position (p) of precipitin bands in OUCHTERLONY’S test with tobacco mosaic virus and carnation latent virus depends upon the concentration of agar and electrolyte. This dependence results from the greater diffusional restriction of antigen in comparison to that of antibody. It is suggested that the effect of electrolyte concentration on the antigen in gel is mechanistically the same as the interaction between virus and agar in the sol state. Antisera against seven distantly related viruses of the potato virus S group reacted with carnation latent, potato M, and red clover vein mosaic viruses. This further demonstrates a serological relationship between viruses of the same shape but different normal length.

The potato cultivars, Pinkeye, Bismark and Brownell have a long history of culture in Tasmania, and contain, respectively, the latent virus complements potato viruses S and Y, potato virus S, and potato viruses S, X and Y. Forms that had been freed of these viruses were compared with virus infected seed lines in two trials that followed local recommendations for optimum tuber yield. Virus-free forms were taller, leafier, darker green, and slightly later in flowering than infected plants. There was greater production of tubers (1 4- 198%) in smaller size grades at immature crop harvests by the virus-free forms of Pinkeye and Bismark; this was offset to some extent by an increase in fertilizer rate. At crop maturity, virus-free forms generally gave a higher yield; this averaged 9.1 % for Pinkeye, 4.6% for Bismark, and 10.3% for Brownell. The increased vigour after virus eradication has not affected commercial acceptance of Pinkeye and Bismark for the production of new, immature potatoes; it has increased second growth problems of Bismark and Brownell when grown to maturity and in part has led to their decline as commercial main crop varieties.

Antisera were prepared to Victorian and Rhodesian strains of Pseudomonas solanacearum, and to a culture of the ring rot organism, Corynebacterium sepedonicum, from Canada. It was found that the two strains of Ps. Solanacearum were similar, though distinct serologically, and each quite different from C. sepedonicum, although there was some serological affinity between the three organisms. The common agglutinins were absorbed to produce specific absorbed serum for each organism, the potential value of which is briefly discussed.
