Erucic acid contamination in rapeseed shows big decrease - NIABTAG Network News, September 2019

Pre-testing Farm Saved Seed oilseed rape samples for Erucic Acid content has paid off by significantly reducing the level of erucic acid in UK crops according to NIABTAG's Simon Kightley in this months NIABTAG Network News....
"The report that we produced for AHDB last year, on erucic acid contamination in rapeseed highlighted volunteers, exacerbated by farm-saving, as the principal cause. This led to a major increase in sample testing at NIAB’s Cambridge laboratory in the run up to sowing last season, with 915 samples analysed. This activity seems to have paid off, with growers and/or seed producers appearing to discard samples with indications of elevated erucic acid content, rather than use for re-planting.
The chart shows that the proportion of samples in the <0.1% category, which we regard as the genetic base in modern varieties, has gone up from 44% in 2018 to 74% in 2019, based on 963 tests this year. Proportions in all the other erucic acid categories identified in the chart have pretty well halved, with the samples above 10% virtually disappearing altogether.
This is very encouraging indeed and, if reflected in commercial samples going for crushing, shows that the problem of contamination can be largely controlled by routine checking of seed for sowing."

"Area of Winter Linseed looks set to rise dramatically" - A. Probert, Farmers Guardian 6th Sept 19

The area of winter linseed this season looks set to rise dramatically, as more growers look to alternative break crops says Andrew Probert, managing director of Premium Crops.
“If you look at what we have as far as autumn break crops there are really only three – wOSR, winter beans and winter linseed. The area of winter rape is going to decline and most farmers have enough beans on their farms.”
The risk of losing OSR crop to flea beetle has meant that 1-2 per cent of last year’s oilseed rape area will be converted into winter linseed, Mr Probert adds.
