Clover, Bluegreen Aphid And Red Legged Mite Screening, Medicago Murex Evaluation, D J. Gillespie

Experimental Summaries - Plant Research

Clover scorch: In spite of poor seasonal conditions, adequate levels of clover scorch developed in the test plots to readily identify susceptible clovers. Of the 333 introductions tested, 23% scored 3.0 or less indicating a high level of resistance. Bluegreen aphid screening: Two hundred and twenty four randomly selected subterranean clovers from all Western Mediterranean collections were tested for resistance to BGA in Nov/Dec of 1983. The susceptibility of annual legumes to Bluegreen aphid. Red legged earth mite screening: Results of two preliminary experiments to develop techniques for mass screening for RLEM resistance in subterranean clover were reported last year. …
