A disease of peanut (Arachis hypogaea L.) in Queensland, previously referred to as "chlorosis", was identified as being caused by the tomato spotted wilt virus. Symptoms of the disease on peanut are described. Erigeron bonariensis L., Tagetes minuta L., and Trifolium subterraneurn L. are recorded as new hosts. The disease was not seed-transmitted, although seeds developed lesions and were malformed. Infective virus was found in tissues of the integuments of immature seed. The maximum disease incidence recorded in an individual crop was 5.5%. The mean seed yield of diseased plants was 12.7 g per plant, whereas that of healthy plants was 128.2 g.

Virus Distribution

Abstract The foliage of individual field-infected peanut plants (Arachis hypogaea L.) was examined by enzyme-linked immunosorbent assay (ELISA) for the presence of tomato spotted wilt virus (TSWV). TSWV was detected commonly in terminals (folded quadrifoliates) and flowers, the vector's feeding and breeding niches. Reconstructions of the assayed plants demonstrated that the virus concentration varied from plant to plant and symptoms were significantly correlated to virus concentration in individual leaves and terminals. The virus was not distributed uniformly throughout individual plants but was concentrated in young, developing terminal tissue. The presence of symptoms was indicative of detectable virus 95% of the time.

Abstract The apparent disease progress of spotted wilt, caused by tomato spotted wilt virus, was monitored in the three component lines of Southern Runner peanut (Arachis hypogaea L.), and in cultivars Southern Runner, Florunner and GK-7 in the field in 1990-1992. In all three years, final incidence and area under the disease progress curves were similar among Southern Runner and all three component lines. Final incidence of spotted wilt in Southern Runner and all component lines was less than for Florunner in all three years. AUDPC values were lower in Southern Runner and two of the three component lines than in Florunner. Incidence and AUDPC of spotted wilt in GK-7 was intermediate between Florunner and Southern Runner and its individual components. Disease increase was linear in all component lines and cultivars. Rate of disease progress was similar among Southern Runner and the three component lines. Disease progressed more slowly in Southern Runner and the component lines than in Florunner.

Summary A recombinant inbred line population of soybean (Glycine max) was utilised to identify the quantitative trait loci (QTLs) determining the response to infection by two root-knot nematode species, Meloidogyne incognita and M. hapla, in glasshouse assays. QTL analysis detected seven major and four minor QTLs on seven soybean chromosomes ((Chrs) 1, 7, 8, 10, 14, 18, 20) explaining 6-41% phenotypic variance (PVE) for M. incognita root response and nematode reproduction. Three of the major QTLs, on Chrs 7, 10 and 18, were confirmed in previous reports and two major QTLs on Chrs 14 and 20 were detected for the first time. The QTL analysis with M. hapla provides the first report of a major QTL region mapped on Chr 7, explaining 70-82% PVE in M. hapla root response and nematode reproduction. These novel identified QTLs with flanking markers will be helpful in marker-assisted breeding for nematode resistance in soybean.
