| Abstract | A virus survey of field pea (Pisum sativum) and faba bean (Vicia faba) crops in southern NSW and Victoria in October, 2006, provided the opportunity to compare the diagnostic results of a large number of field samples using reverse transcription polymerase chain reaction (RT-PCR) to the accepted reference test of tissue blot immunoassay (TBIA). One hundred unbiased plant samples from each of 21 field pea and three faba bean crops from NSW and ten field pea crops from Victoria were tested for Alfalfa mosaic virus (AMV), Bean yellow mosaic virus (BYMV), Cucumber mosaic virus (CMV), Pea seed-borne mosaic virus (PSbMV), Bean leafroll virus (BLRV) and Beet western yellows virus (BWYV) by TBIA. PSbMV was present at high levels (32–77 %) in 12 out of 21 field pea crops sampled from NSW. BLRV was present at high levels (28–42 %) in faba bean crops from NSW. In Victorian field pea crops, BWYV was most prevalent (4–28 %). Other viruses tested for were present at low incidences or absent. The seed to seedling transmission rate of PSbMV in the field pea seedlots used to sow six of the surveyed NSW pea crops, determined by TBIA, ranged from 0 to 23 % and had a clear effect on the level of PSbMV in the field. Test results for PSbMV and BLRV using TBIA were compared with results using RT-PCR and compared favourably in giving similar estimates of infection incidence and low costs (both less than A$1.00 per sample) for detecting these two viruses. It is concluded that TBIA is the preferred technique to get a precise estimate of infection incidence, while RT-PCR is particularly useful to test bulk samples for the presence of viruses with a low incidence and provides an alternative if antiserum is not available. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
