Yielding a massive 5% more than any other variety on the 2021 BBRO Recommended List, BTS 1915 leads the pack, with an adjusted tonne yield of 108.1% and a high sugar content of 17.7%.

Bred by Betaseed and marketed by Limagrain UK, BTS 1915 leads the Recommended List by a considerable amount - 5% over any other variety - and this is exceptional. Next on the list is KWS Evalotta yielding 103%, followed by last year’s list topper KWS Kortessa at 101.9%, so it’s clear to see the exceptional yield increase brought by BTS 1915,” explains Ron Granger, sugar beet product manager for Limagrain.

“We normally expect to see year on year yield advances of 1-2% in yields – so BTS 1915 is something quite special - and this is at a time when many other arable crop yields have plateaued.”

“Nor is it a one year wonder performance” he adds. “These extremely high yields have been consistent over the last three years that the variety has been in trials - so we are confident in the variety’s ability to perform in different seasons and situations.”

“We are also in the fortunate position where sugar beet breeders are still able to push yields without compromising the sugar content – and this is reflected in BTS1915 with its very acceptable sugar percentage of 17.7.”

Nor is it all about the yields, he continues. “BTS 1915 has excellent agronomic characteristics that make it a very useful variety on-farm. We recognise that varieties also need to establish well, have good bolting tolerance and robust disease resistances to succeed.”

“However when BTS 1915 is sown in the normal sowing window from mid-March onwards, it has shown an excellent bolting tolerance, recording no bolters. This result has been consistent over the last three years, including data from 2019, which we know was a high year for bolting.”

“However, it should be recognised that when BTS 1915 is sown early, the variety might show excessive botling as the Early Sown Bolter trials, conducted as part of the Recommended List trial series demonstrate. “

“The variety has the highest brown rust disease resistance rating on the Recommended List of 8.7 , thus making it the first choice for late lifting where brown rust is potentially the key disease to control.”

PANEL

BTS 1915 provides an opportunity for growers who want to take the next step-up in yields as in doing so they are raising the bar in sugar beet production even higher - making themselves more resilient against the rising costs of producing a sugar beet crop.

According to figures from the John Nix Pocketbook for Farm Management 2019 edition, the additional benefits of this 5% yield are significant in terms of profitability, irrespective of the crop being low, average or high yielding.

Increasing the yield by 5% on a crop yielding 66.5t/ha by 3.325t/ha brings a financial benefit of £67/ha. For a crop yielding 78t/ha, a 5% increase in yield of3.9t/ha is worth £79.80/ha and on a crop yielding 89.5t/ha an extra 5% benefit in yield of 4.475t/ha is worth £91.51/ha. This is based on a 2020 beet price, on a three-year contract at £20.45/t with no crown tare reduction.

BTS 4100 joins the 2020 BBRO Recommended List with the highest sugar content of any sugar beet variety, whilst also offering high yields and low bolting counts at early sowing.

Bred by Betaseed and marketed by Limagrain UK, BTS 4100 offers the highest sugar content of any sugar beet variety on the list at 18.4%, and has produced these high sugar levels consistently over the last three years in Recommended List trials.

“In 2016, BTS 4100 yielded 18%, whilst the average sugar percentage across the RL trials was 17.7%. In 2017 when the national average was 18.4%, BTS 4100 yielded 0.6% more at 19%. In 2018, the national average was 17.8% and BTS 4100 again yielded 0.6% more, at 18.4%,” says Ron Granger, sugar beet product manager at Limagrain.

“Growers will recognise that on certain soil types or in difficult field conditions, a high sugar content can be hard to achieve; in these situations a variety such as BTS 4100 with a genetically high sugar content offers the best insurance for maximising full yield potential, as expressed in adjusted tonnes”.

Along with these extremely high sugar levels, BTS 4100 offers high adjusted tonne yields of 101.8% -reflecting a step-up over some of the older varieties on the list.

However, whilst yield and sugar content are the top criteria for choosing a new sugar beet variety, factors such as establishment and bolting tolerance are also very important – particularly when deciding which variety is best for your situation, adds Mr Granger.

“For those looking to drill in the first half of March, in an attempt to get crops up and away to combat virus yellows infection, BTS 4100 fits this drilling slot very well. It has excellent bolting tolerance and is one of only a few varieties on the RL, that offers no bolters when drilled in the normal sowing slot.”

“This is combined with good emergence characteristics and a good tolerance to rust. It is also Rhizomania tolerant.” To sum up, BTS 4100 is a high yielding variety with the potential of achieving a top sugar percentage, and also fits the early drilling slot.”

Newly recommended sugar beet variety BTS 1140 reflects the increasing yield potential of sugar beet. This comes hand in hand with excellent sugar content and favourable on-farm agronomics such as low bolting figures at normal sowing date and very good disease resistance.

Bred by Betaseed, and marketed by agents Limagrain UK, the 2019 BBRO Recommended List (RL) clearly shows that the yield potential of BTS 1140 is significantly above the most widely grown varieties in 2018, yielding 107.6 % (adjusted tonnes), over three years of trials. BTS 1140 also has a high sugar content of 18%.

This significant 2-3% increase in yields seen each year in newly recommended sugar beet varieties on the RL is very exciting for the UK’s sugar beet growers. This year the newly recommended varieties offer a 7.6% increase over the control varieties, says Bram Van der Have, sugar beet consultant for Limagrain.

“We are in the fortunate position where breeders are still able to push yields without compromising the sugar content – and this is at a time when many other arable crop yields have plateaued.”

However, the value and importance of on-farm characteristics of sugar beet to UK growers is also reflected in this recommendation, he adds. “Whilst yield and sugar content are the top criteria for choosing a new sugar beet variety, factors such as establishment and bolting tolerance are also very important – particularly when deciding which variety is the best for a certain situation.”

“For those looking to drill at the normal to later time from mid-March onwards, as most growers will have done this season, BTS 1140 fits this drilling slot very well. It has excellent bolting tolerance – with only 14 bolters per 1000,000 plants/ha – one of the lowest on the RL list. This is combined with good emergence characteristics and a good tolerance to rust. It is also rhizomania tolerant.” “BTS 1140 is likely to appeal to the grower who wants to take the next step up in yields, and we would encourage growers to try it and take part in raising the bar in sugar beet production even higher.”

2017 saw some of the highest sugar beet yields ever; Limagrain’s varieties BTS 860 and BTS 3325 were no exception and lend themselves well for repeat sowing for the 2019 season.

In fact, BTS 860 was one of the most popular varieties grown in 2017/18 as it has shown itself to be a consistent performer that offers very high yields at 103.9% of controls, alongside one of the highest sugar contents on the Recommended List at 18.2%, says Mr Van der Have.

“Annually, a small part of the national crop is drilled in the early part of March. Early Sown bolting tolerance for varieties sown this early is a key characteristic and BTS 3325 has proven performance in this sector, both commercially and in trials.”

“BTS 3325 has the potential to out-yield many of the traditional varieties drilled in the early sown sector, with the additional benefits of a very high sugar content (18.3%), and excellent disease resistance for rust and powdery mildew.”

HIGH PERFORMANCE ON-FARM

Michael Wilton of Stody Estate in Norfolk, is always looking for the best performing sugar beet varieties on the Recommended List which means he only grows an individual variety for two-three years.

“I want a variety that is high yielding with a good, quick establishment percentage as I believe that the two things go hand in hand. A consistent high sugar percentage which increases sugar yield per hectare is what we ultimately get paid for.”

“We grow 240ha’s of sugar beet which is split across 4 varieties. I drill after 5th March, so am looking for a normal drilling, low bolting variety.”

For these reasons Mr Wilton chose to trial 60ha’s of BTS 860 in 2017. “The crop established very well, even on lighter soils. What stood out was its green leaf retention which was good right through the season, so yields continued to build until harvest, which made the variety suitable for late lifting.”

“All of the BTS 860 yielded slightly above the farm average, but one single field that was irrigated stood out, giving us our highest field yield for 2017 at 112t/ha adjusted yields. This well up on our average farm yields by about 15%. The late lifting also delivered sugars above the farm average of 18% at 18.6%.”

“Based on this excellent performance, we will definitely be growing the variety again this year.”
