PCA upgraded its receival, shelling and grading plant at Tolga to counter the possibility that the problem was resulting from peanuts growing in potato crop soil... But Dr Wright says reducing the allowable moisture content to eight per cent has increased the tendency for peanut kernels to split, resulting in the need to compensate growers... IMAGE CAPTION: Dr Graeme Wright says a musty, earthy taste detected in peanuts in 2008 and 2009 might develop in the soil, windrow or storage ...

GRDC investment drives peanut research.. Plants infected with the Neocosmospora vasinfecta fungus suffer symptoms such as chlorosis and wilting, and this has been known to cause peanut yield losses of more than 50 per cent in some areas... Ms Wenham's project aims to develop potential management options and strategies for the disease by answering questions about how N. vasinfecta is dispersed in the field, how infection takes hold in plants, and whether plant injury, nutritional deficiency, or abiotic stresses have an influence...

Preventing costly peanut contamination.. Peanut growers now have clear advice on how to prevent costly contamination of their crops, following research supported by the Grains Research and Development Corporation (GRDC)... The research led by Dr Graeme Wright, of the Peanut Company of Australia, revealed that microorganisms called actinomycetes, which can grow on freshly harvested and stored peanuts, produce volatile compounds that cause the off-flavours...

New research investment to tackle peanut disease.. Peanut root rot has caused more than 50 per cent yield losses and cost the Australian peanut industry several million dollars in bad years... Ms Wenham's project aims to develop potential management options for the disease by answering questions about how N. vasinfecta is dispersed in the field, how infection takes hold in plants, and whether plant injury, nutritional deficiency or abiotic stresses have an influence...

Leading the program, Peanut Company of Australia (PCA) manager Dr Graeme Wright says advances in peanut pre-breeding over the past 18 years have seen short-season varieties achieve about 90 per cent yield parity with their long-season counterparts... Further highlighting the pre-breeding progress, genetic gains for foliar disease tolerance have increased 10-fold in the past eight years, reducing growers' total expenditure on spraying (for leaf spot, leaf rust and net blotch) by $200/ha to $300/ha, Dr Wright said... "In dryland situations when opening rains do not arrive in time for the traditional sowing window from November to December, early-maturing varieties can be late-sown in January," Dr Wright said...

By Rebecca Thyer For the third year running, the traditional heart of Australia's peanut cropping industry - Kingaroy in south-east Queensland - has faced drought, severely affecting yields... [Photo (left) by Brad Collis: Graeme Wright] After about 20 years with the Queensland Department of Primary Industries and Fisheries (QDPI&F) at Kingaroy, the GRDC Northern Panel member has joined the Peanut Company of Australia (PCA), where he plans to continue his work of boosting productivity for peanut growers through breeding and better agronomy... Dr Wright will oversee a proposed joint project between PCA, QDPI&F and the GRDC to improve varieties for Kingaroy's traditional dryland growers and newer irrigated growers, based near Bundaberg and Mackay, in north Queensland and in the Northern Territory...
