Field and glasshouse methods of assessing the resistance of potato varieties to common scab were investigated and procedures which were found to give satisfactory results are described in detail. Estimates of resistance for individual varieties in the two environments were closely correlated. Examination of a number of isolates ofStreptomyces scabies showed(More)
Potato plants were grown in pots of compost containing inoculum ofStreptomyces scabies at several soil moisture contents maintained by capillary watering or by hand watering. Scab incidence was inversely, and tuber yield directly related to soil moisture content. Conditions conductive to high levels of scab infection can conveniently be provided by(More)
Methods used to test for virus infection in potato samples from South America are described and the incidence of infection in the samples is recorded. Samples were classified according to provenance, ploidy, altitude of collection, and as weed or cultivated forms to investigate the influence of these factors. The advantages of maintenance of potato(More)
The presence of the genes R 2, R 3, R 4 and R 6, in various combinations, was demonstrated in seven lines of Solanum stoloniferum by inoculation of progenies derived from them with specialized races of Phytophthora infestans; two other lines were fully susceptible. The inheritance of these genes in S. stoloniferum can be interpreted on a disomic basis.
If emergency GPS is to continue in the DGH, commissioning health authorities and trusts must recognise the needs of these willing surgeons in terms of additional support for CPD to ensure a quality service can be maintained locally. If solutions are not found, tertiary paediatric centres will undertake larger GPS caseloads at the expense of specialist(More)
From June 1999 to June 2000, 480 environmental swabs were collected from two abattoirs in Northern Ireland. In addition, from July 1999 to July 2000, 420 samples originating from raw cow's milk were collected from two Northern Ireland dairies. All samples were examined for the presence of verocytotoxin-producing Escherichia coli (VTEC). O157 with the use of(More)
