Cold weather, national lockdown dull potato demand in Britain

Throughout February, free-buy and contract demand remained quiet across the board. Cold and snowy weather at the start of February, combined with the national lockdown, curbed many opportunities to eat out-of-home, therefore dulling demand. February saw the release of the GB end of January stocks figures . This pegged grower held stocks at 2.11Mt, 39% of total production. This is 47.36Kt lower than last year but 40.86Kt higher than the 5-year average

Research: AI model successfully predicts potato susceptibility to bruising and acrylamide formation

JADBio is an information technology company based in the US and Greece, focused on BioMed and Multi-omics. In a recent experiment, researchers at JADBio collected data from 478 potato samples from potatoes grown in Germany (including climate, soil, and metabolic profiles) in order to create a model capable of differentiating potatoes that resist bruising from those that don’t, and also to predict the potatoes’ susceptibility to acrylamide formation during chip/crisp processing.

Research: ‘Tunable crops are just a spray away’

The genetic control of crop growth and behaviour can be modified through traditional plant breeding or genetic engineering, but is fixed once a variety is sown. New spray-on viral transfection technology can transiently alter gene expression to “fine-tune” agronomic traits within the season while avoiding modifications to the genome according to recent research.

The glyphosate debacle: Viewpoint on ‘a misleading study, gullible reporters, and a cancer scare’

“As biotech giant Bayer prepares to spend $10 billion settling thousands of lawsuits alleging its weedkiller Roundup (and its active ingredient glyphosate) causes cancer, we’re forced to address a crucial question: how does an herbicide deemed safe by regulators and scientists the world over become the whipping boy of tort lawyers and environmental groups with an ideological ax to grind?” So says Geoffrey Kabat in a recent article published by the Genetic Literacy Project (GLP).

Zebrachip disease and potato psyllid: EFSA survey card helps preparing surveillance plans

Scientists recently updated the pest survey card that was prepared in the context of the European Food Safety Authority (EFSA) mandate on plant pest surveillance at the request of the European Commission. The authors say in the introduction to the document that its purpose is to guide the Member States in preparing data and information required for surveys of the causal agent of the zebra chip disease ‘Candidatus Liberibacter solanacearum’ (Lso) and its associated insect vector the psyllid Bactericera cockerelli.

New research identifies best gene to confer durable resistance to late blight in potato

An international team of researchers has struck an important blow in the ongoing evolutionary arms race with the notorious potato disease late blight (Phytophthora infestans). This disease, which caused the Irish potato famine in the 1840s, continues to reduce potato yields today and can lead to devastating losses. A new gene and it’s relatives were found in the Solanum americanum plant and seem to provide potatoes resistance against all races of P. infestans . A publication on the new Rpi-amr1-gene appears today in the journal Nature Plants.

New decision-making tool to calculate tuber numbers, predict yield

Growers should soon be able to assess the variation in potato plant populations at field scale at any given time. This is thanks to work done by Harper Adams University, AHDB funded PhD student Joseph Mhango. His new decision-making tool uses artificial intelligence known as Deep Learning alongside drone-taken images of the crops to calculate stem numbers, and map where they occur. This technique is able to detect objects, and is used for machine vision in self-driving cars.
