Plant breeder Limagrain has confirmed that hybrid oilseed rape LG Antigua offers the N-Flex trait – meaning it can use nitrogen more efficiently.

In the field, this means that varieties with the N Flex trait are better able to withstand delayed or sub-optimal nitrogen applications. It makes LG Antigua a four-trait variety encompassing TuYV, pod shatter and RLM7 resistance – and now N-Flex.

Confirmation of the trait follows extensive Limagrain trials over the last few seasons in Europe. The breeder says it has tested LG Antigua’s performance in optimal and sub-optimal nitrogen conditions.

“Essentially the N-Flex trait means that hybrids containing the trait use each unit of available nitrogen more efficiently than those which don’t,” says Limagrain UK arable marketing manager Will Charlton.

The addition of the N-Flex trait was a good example of Limagrain’s approach to producing hybrid oilseed rape’s that were trait-loaded, said Mr Charlton. Varieties with the N-Flex trait produced more stable yields year to year, with less in-field yield variability.

High yielding varieties Ambassador and LG Aviron were the first four-trait loaded varieties, offering genetic resistance to TuYV , pod shatter, RLM7 and the N-Flex trait. LG Antigua now joins this line-up.

“We are carrying out further work in farmer split field trials for the 2020-21 cropping year to evaluate how N-Flex aids spring nitrogen management and secures yields,” said Mr Charlton.
