New Group 4 is consistent and flexible

by Arable Farming Magazine July 2022 issue

A high yielding Group 4 hard wheat, new to the AHDB Recommended List (RL) for 2022-2023, will be available to UK growers this autumn.

New from Limagrain UK, LG Typhoon is a high yielding, consistent and resilient hard wheat, with a solid all-round disease package and orange wheat blossom midge (OWBM) resistance.

According to Limagrain UK arable technical manager Ron Granger, the variety delivers consistency of performance across very different seasons and regions of the UK.

A great attribute to have in any variety, he says.

Mr Granger acknowledges that while yield is important, growers fundamentally like to grow robust varieties that deliver time and again across seasons and rotations.

He attributes LG Typhoons consistent performance across locations, seasons and rotations to the varietys all-round foliar disease resistance and agronomic characteristics.

It has a very good untreated yield ; an important attribute even in the hard feed sector, that was traditionally high input, high output, and is a valuable tool regarding fungicide programmes and timings, he says.

Septoria resistance LG Typhoons septoria resistance rating of 7.2 (three year data set) is derived from a combination of genetic sources different to those of the majority of current RL varieties, and is a significant factor in protecting this resistance rating going forward, adds Mr Granger.

It has an excellent yellow rust resistance of 9, combined with YR seedling resistance; a valuable insurance around the earlier spray windows of T0 and T1, where yellow rust can be the main focus in regional high pressure situations.

Mr Granger believes a lot of second wheats could be drilled this autumn, given the high price of wheat, and highlights LG Typhoons excellent performance as a second wheat yielding 104% of control, putting it among the most popular varieties in this rotational position.

It is a high-tillering variety that performs well at low seed rates and can be drilled from mid-September to mid-February, however, it exhibits a genuine suitability for the earlier sowing situation, yielding 105%.

LG Typhoon is slightly later to mature (+2), similar to Costello, but Mr Granger does not see this as an issue.

As we learned with our variety Revelation , it is important to have a range of maturities across the farm to spread harvest risk in catchy seasons, he says.

LG Typhoon has a good specific weight (76.3 kg/hl), similar to that of Gleam.

How LG Typhoon fits a regenerative farming system

There is still much uncertainty about what varieties best suit a ‘regen farming system, says Mr Granger.

However, we know that wheats in a regen system tend to be direct drilled, and in some circumstances early drilled, which means they need to sit back, and not race off too fast in the autumn or early spring, which has implications regarding agronomy inputs and programmes.

In our trials last year, where we compared the behaviour of varieties when drilled in this situation, we found LG Typhoon did just this, sitting prostrate with a slower plant growth through winter into spring.

The variety is very high tillering and this attribute, combined with the fact that it filled the wider rows with a very high head count, made it the standout variety in this situation.

Its excellent disease profile along with orange wheat blossom midge resistance, allows for some flexibility with inputs which again suits a regen system, he adds.
