Having reviewed the many and complex reasons why farmers yields have reached a plateau, NIAB TAG is demonstrating at Cereals 2013 the research, breeding and agronomy that will allow UK growers to achieve the genetic yield potential in their wheat crops.
Wheat yields in trials are increasing by about 1.0 t/ha per decade but on-farm yields reached a plateau about 10-15 years ago. Clearly there is yield potential in new varieties that is not being realised. NIAB TAG research is focused on developing new genetic traits, particularly higher yield potential and finding solutions to agronomy problems to enable UK farmers to raise their wheat yields.
Eight wheat varieties with markedly different and yet successful phenotypes provide the backdrop for the exhibit, showcasing the components and restrictions to yield, quality and agronomy. These include high yielding variety Wakanui from New Zealand, one of NIAB’s own non-GM ‘synthetic’ wheats; a later, stiff-strawed, high yielding line, and an early-flowering MAGIC pre-breeding wheat line.
“Wheat yield is strongly governed by rainfall and sunshine during grain filling, both of which had major impact on yields in 2012,” explains NIAB TAG’s commercial technical director Bill Clark. “But the decisions we make on agronomic inputs, variety choice, crop management and cultivations can also have a large impact on winter wheat yield and margins.
“The NIAB TAG stand at the Cereals Event is an opportunity to see the breadth and volume of the organisation’s work along the crop development pipeline from pre-breeding initiatives through to our field trials and onto advice on-farm.”
NIAB is looking at new sources of genetic potential from ‘synthetic’ wheats and MAGIC wheat lines to help raise the yield of varieties on farm. Achieving the yield potential of these new varieties will involve integrating agronomic inputs including nitrogen and fungicides as well as soil management.
‘Synthetic’ wheat breeding - crossing the wild grass species Aegilops tauschii into modern wheats – recreates the original cross that led to the development of bread wheat in the Fertile Crescent 10,000 years ago. It brings new genetic diversity into modern plant breeding programmes which offer better disease resistance, drought tolerance and higher yields.
MAGIC is NIAB’s ‘Multi-parent Advanced Generation Inter-Cross’ plant breeding programme, a six-year study that has produced over 1,000 new wheat lines. MAGIC lines encompass more genetic diversity because they have been produced using eight parent varieties in a complex crossing scheme, rather than the usual two.
Visitors will also have the opportunity to try their hand at plant breeding by making variety selections on four MAGIC lines. “We want growers to think back to the variety types that did well and badly in the 2011-12 season, then assess our MAGIC lines and guess their final 2012 yield ranking,” says NIAB TAG plant breeder Phil Howell.
“Our aim is to simply show the complex science behind today’s plant pre-breeding and breeding programmes and how this new genetic diversity will eventually end up in the varieties grown on-farm.”
NIAB TAG’s variety demonstration plots feature thirty established and new winter wheats and twelve winter oilseed rape. Clare Leaman, Simon Kightley and a team of NIAB TAG specialists will be available with advice and recommendations on variety choice across all combinable crops, including winter barley and pulses.
Pathologists Dr Rosemary Bayles and Dr Emma Coventry will also be available in the variety plots with the latest research and advice on yellow rust and Dr Jane Thomas and Dr Tom Wood will be present to cover oilseed rape and pulse crop disease issues.
Global challenges are fostering innovation
The NIAB Innovation Farm plots are demonstrating a cross-section of innovative industry and scientific solutions that exploit plant genetic resources and address the challenges of food security, climate change, sustainable resources and health and nutrition.
Soils, roots and holes
Our man in a hole in the ground is back again this year. Nathan Morris will be revealing The Hole Story, demonstrating the importance of maintaining a healthy soil and the methods farmers can adopt to influence soil structure to ensure optimum crop yields. He will be supported by colleagues from the Cambridge Agronomy Unit.
“A well structured soil can help water infiltration and aids moisture retention, increases soil aeration for root growth and biological function, improves the workability of the soil and reduces the energy required for cultivating the soil – saving time and fuel,” says Nathan.
Other features available on the NIAB TAG stand include:
- Analytical Services – exploring the disease, plant clinic and variety identification services as well as seed and produce quality testing, available through NIAB TAG’s LabTest service;
- Variety evaluation and testing services – explaining the background behind the statutory DUS (Distinctness, Uniformity and Stability) and VCU (Value for Cultivation and Use) variety testing carried out by NIAB specialists;
- NIAB TAG Network membership services – sign up for three months free access to the top of the range Agronomy membership including field days, trials results, unique regional variety information and weekly agronomy updates through the season.
