Summary of the impact
Oats are recognised as a healthy grain reducing the risk of coronary
heart disease and as a
valuable grain for livestock feed. Research within BEAA has provided the
genetic, physiological
and agronomic knowledge that underpins the breeding of high yielding
husked and naked oat
varieties that meets the needs of end-users in the human food and
livestock sectors. BEAA bred
oat varieties account for approximately 65% of the UK market and have a
significant impact on
health and welfare, the economy and on production and support the
expanding instant oat
breakfast market sector that alone is worth £160million per annum.
Underpinning research
Research conducted within BEAA through BBSRC, DEFRA, AHDB-HGCA and
Sustainable Arable
LINK funded projects, over the period 1993-2013 has underpinned the
breeding of new oat
varieties for human food consumption, as a livestock feed and as a source
of novel compounds for
industrial applications. Research by Leggett (Aberystwyth,1972-2004) and
Carver (Aberystwyth,
1975-2007) focused on the identification of key traits (dwarfing genes,
disease resistance [3.1])
that would enhance the value of oats for end-users, the potential for
exploiting wild relatives of
hexaploid oats as a source of novel genetic variation and made significant
advances in the
development of the genetic tools and resources available to plant breeders
that enable genetic
information on key traits to be more readily applied within the oat
breeding programme. In
recognition of this approach the variety Gerald, first RL listed in 1993,
won the NIAB Cereals Cup
in 2003 and dominated the winter oat market for a number of years [3.2].
Recognition of the
subsequent breeding activity is also evidenced by the addition of
varieties to the UK recommend
list for cereals [3.2] and of the scientific quality of this research by
the award of several major
research grants during the REF period [3.3].
The value of oats for both human and livestock consumption is related to
the specific composition
of the oat grain. Oats are regarded as a healthy human food due to the
composition of the grain,
specifically the β-glucan content. Analysis by Leggett of oil content
and composition [3.4] and beta-glucan
content [3.5] has underpinned the oat breeding programme for both sectors
and quantified
the variation in β-glucan content within and between cultivated oats
and their wild relatives and so
released the potential for exploitation of wild relatives as a source of
novel genetic variation. More
recent research by Howarth (Aberystwyth, 1985-present) [3.6] on DArT
marker development has
enabled the breeding of varieties with high levels of β-glucan.
Oats are regarded as a high value animal feed. Naked oats have a
non-lignified husk that is
removed during harvesting. Research by Ougham (Aberystwyth, 1983-2010)
[3.7] was carried out
on the contrasting reproductive development of naked and husked,
specifically lignin deposition.
Later research showed that the naked oat trait greatly increases the
metabolisable energy (ME) for
poultry, for which the husk is almost indigestible. Research by Cowan
(Aberystwyth, 1989-present)
[3.8] has since shown that oats are a high-energy grain suitable as a
monogastric feedstuff with a
well-balanced protein composition rich in essential amino acids. This
makes naked oats ideal for
inclusion in animal diets as an energy source and has underpinned the
breeding of naked oat
varieties and demonstrated their value as a high value feed for
monogastrics.

Details of the impact
BEAA's research on oat genetics has made a significant contribution to
the breeding of innovative
oat varieties that have had considerable impact [5.1]. Oat breeding within
BEAA also formed part
of the award of the Queens Anniversary Prize for 2009 that was awarded to
Aberystwyth University
[5.2] in recognition of combining fundamental research on plant genetics
with plant breeding
techniques to develop new commercially viable plant varieties that are
designed to tackle some of
the pressing issues faced by communities across the world, those of food,
water and energy
security.
Impacts on health and welfare:
Public awareness of the merits of healthy food and the health benefits of
consuming oats has
increased over recent years. This coincides with the publication of the
health claim on oats by the
EU [5.3] that accepts that eating oats contributes to a reduced risk of
coronary heart disease
because of their β-glucan content. BEAA's research on variation in
β-glucan content in oats has
identified sources of high β-glucan that has been incorporated into the
winter and spring oat
breeding programmes, providing suitable varieties for the UK milling
industry. The BEAA oat
breeding programmes account for approximately 65% of the oats used within
the UK [5.4] and
varieties from that programme contribute to market diversification in oat
based products within the
breakfast cereal market and for snacks or light meals for consumers. There
is a growing demand in
the UK for on-the-go convenient breakfast foods. As a result, consumers
are increasingly opting for
cereal bars, instant porridge and other breakfast solutions. The oat
varieties bred by BEAA are
marketed through a strategic alliance with the company Senova [5.5]. The
utility of the new oat
varieties in terms of milling quality is tested in collaboration with the
British Oat and Barley Millers
Association, which represents the major oat milling companies within the
UK. In 2012, the quantity
of oats used within the UK was ca.700,000t of which 65,000t was imported,
with 450,000t milled for
human food consumption [5.4].
Impacts on commerce:
BEAA oat varieties based on our research activities [section 2] account
for approximately 65% of
the oats used in the UK and have a significant impact on the agriculture
sector. The instant market
for oats in the UK as of May 2013 is worth more than £120 million, with
"Oats So Simple" alone
worth £97.3 million [5.6] and is now the 3rd most valuable
cereal in the UK. Porridge sales are £40
million putting the UK market for hot oat cereals at over £160 million.
The BEAA oat varieties also
impact on other sectors: the ready to eat cereals, granolas and mueslis
market is approximately
worth £19 million and bars and biscuits nearly £10 million. Sales of
oat-based products are
increasing at 5% per annum. BEAA research thus contributes to the improved
human diet as a
consequence of the increasing popularity of oats in the retail market.
Economic impact is not only
in the UK as the UK is also a major exporter of oat products into Europe,
the Middle East, Africa
and Asia; 55% of the output of the QUAKER mill at Cupar is exported and
almost all as packed
retail products.
In the UK the majority of the oat crop comprises BEAA's winter oat
varieties; spring oats represent
ca. 25% of the crop. The Crop Evaluation Limited Recommended List (RL) of
winter oats is
currently dominated by BEAA varieties (eg 100% in 2012). The winter oat
variety Mascani, bred by
BEAA (RL listed in 2004), is currently the most widely grown, accounting
for nearly 50% of the
current winter oat seed sales [5.7] with 60,000ha of land sown for
production of this variety. Two
BEAA bred spring oat varieties (Glamis and Conway) are currently on the UK
National List and are
in RL trials. The oat crop is used for human food and also for animal
feed; the BEAA breeding
programme introduced the `naked oat' types in which the husks thresh free
from the groat during
harvesting, and these are favoured as feed for pigs and poultry. The BEAA
naked oat breeding
programme has bred varieties with high oil content and high ME value
making them a quality
animal feedstuff. Three (of 9) RL varieties of winter oats and one spring
oat (Lennon) listed in 2012
are naked oat varieties bred by BEAA [5.7], further emphasising the impact
of the BEAA breeding
programme on the diversification of the market for the oat crop. The
merits of these naked oat
varieties, marketed by Agrii [5.8] are listed in the UK RL guide 2012/2013
[5.7]. Approximately
8500t were produced in 2012 with 18.8% going to the poultry sector, 14.1%
to pet food, 9.9% for
bird food, 16.4% for pigs and 40.8% for horses and malting.
Impact on production:
The BEAA research on dwarfing genes in oats has enabled the development of
dwarf varieties,
such as Balado, added to the UK RL in 2010, that reduce the risk of
lodging [5.9], and the need to
apply plant growth regulators to control plant height. This is evidenced
by the relative performance
of dwarf oats in comparison with conventional height oats with and without
plant growth regulator
(PGR) treatment [5.9]. Balado is the highest yielding winter oat currently
on this list [5.7]. The dwarf
oats have a significant impact on the production of oats and on the
milling industry where grain
without PGR is increasingly important, particularly for the export market
to Scandinavia [5.6].
Research on disease resistance has also enabled varieties with improved
resistance (such as
Mascani) to be bred, reducing the need for fungicide application. The UK
Recommended List for
Cereals [5.7] 2012/2013 provides details of the disease resistance of the
different varieties
