Cucumber Mosaic Virus In Lupins., D. A. Nicholas

Experimental Summaries - Plant Research

Cucumber Mosaic virus in lupins.

A testing service for lupin growers was provided by the Seed Testing Station. The level of CMV in seed was determined in a 1000 seed sample using the ELISA (Enzyme Linked Immunosorbent Assay) technique developed by Dr. R.C. Jones.To speed up processing of samples levels greater than 1.2% were not determined - to do so would have required repeating the test at a different level of grouping. Growers were charged $114 per sample tested. The service was advertised as being available for samples received up until 28 February.

National Subterranean Clover Improvement Programme., P. G. H. Nichols

Experimental Summaries - Plant Research

The National Subterranean Clover Improvement Programme (NSCIP) aims to develop, by breeding and selection, better adapted and more productive low—oestrogen cultivars of subterranean clover for a range of environments in southern Australia. The programme is a collaborative one with the University of Western Australia and consists of two phases: (i) early generation selection, which involves selecting varieties satisfying primary selection criteria; and (ii) field evaluation of advanced lines, which is conducted by the Departments of Agriculture in each State and co—ordinated by the Plant Breeder.

The first phase is conducted at the University Field Station (UFS) and is continued until …
