Agrivice Variety Trials 2003. |
The final planting survey indicates that wheat
plantings in Great Britain are 8% down on last year. At the present time yields
look promising and prices remain firm. Choosing the correct variety is of the
utmost importance. This choice involves many factors. However, the overriding
factor must be the end market potential. You will need to delve into this and
seek any local or national markets, any special marketing niches for the
variety in question or its ability to suit the requirements for export markets
that may be available. Choice of variety will also need to be made around:
Its suitability for early or late drilling, and
whether the variety is suitable for 1st, 2nd or the continuous wheat
situation.
Does the variety have good disease resistance or
does it require a comprehensive fungicide programme? Is it a chlorotoluron safe
variety?
Have we the sprayer capacity to be on time with our
fungicide programme?
If not, are we better with a low yielding low
disease problem variety.
Can our combine capacity cope with a variety than is
prone to sprouting?
All these questions need to be considered. Please
take the opportunity tonight to ask any questions that may help you make the
correct decision on the choice of variety for the coming season.
Malacca Group 1. A popular hard
endosperm bread-making variety now widely accepted by millers, with 9% market
share. Its protein potential is a little lower than that of Hereward, however,
its yield is some 7% higher. It has short, stiff straw and early maturity with
good resistance to yellow rust, brown rust and septoria nodorum. It gives grain
with high Hagberg Falling Number and high Zeleny values but with moderate
protein and specific weight values. (Breeder CPBT 97 Riband x (Rendezvous) x
Apostle)
CPBT W84
Group 1. Hoping to fit the milling wheat situation but has since been dropped.
No further work will be done on its development
Xi 19 Group 1.
A hard endosperm variety. Yield is reputed to
be 4% above that of Malacca and so is comparable with top feed varieties. Good
all-round disease control but can be prone to fusarium ear blight and possibly
ergot. Moderate straw strength and longish straw so avoid drilling too early.
Will need good management to achieve high proteins. On average it has given
protein content 0.4% below Malacca. Average proteins - about 11.8% in trials.
(Breeder Advanta 103 (Cadenza X
Rialto) X Cadenza)
Option Group
2. A hard
endosperm variety with acceptable bread making potential. Replacement for the
variety Rialto. Due to having a Chopin alevograph P/L ratio of 1.5 it is less
suited to export bread-making markets but suits export-blending markets. It has
given high treated yields, particularly on the lighter, less fertile soils. 6%
of seed certified ex-harvest 2002 down to this variety. Rotationally it has
preformed well as a second wheat. It is a relatively fast developing variety
and so would be suited to mid to late sowing. It has good resistance to yellow
rust but is susceptible to mildew and the septorias. It has given grain with
high specific weight, Hagberg Falling Number and Zeleny values but moderate
protein content. (Breeder PBI 101
Rialto ‘sib’ X Vivant). Could be prone to ergot.
Charger Group
2. A hard
endosperm variety that is specially recommended for later sowing when it has
given relatively high yields. It has relatively weak straw if sown early but
stands better when late autumn sown. It is early to ripen with good resistance
to yellow rust but is susceptible to fusarium ear blight. It has given grain
with a moderate protein content but very high Zeleny values. It suffers from
low sprouting resistance, so needs high priority at combining. (Breeder PBI
98 Fresco ‘sib’ X Mandate)
Solstice Group
2. Hard endosperm wheat with some bread making quality. It is at the top end
of group 2 bread making. Very stiff, moderately long straw. Slightly better
protein than Option but 2% down on yield. Good resistance to yellow rust but
susceptible to brown rust. It gives a large grain with a reasonably high
specific weight and Hagberg Falling
Number. Good for early drilling but could be prone to ergot if drilled very
early. (Breeder Advanta 100 Vivant X
Rialto)
Bentley
Group 2. High yielding, hard endosperm bread-making wheat with excellent
specific weight (78.8), a high Hagberg Falling Number (261) and yield similar
to Savannah. Some lodging in untreated trials but extremely low incidence in
treated trials. Likely score for straw length 8 where treated and 6 when
untreated. It has medium to late maturity about 1 day later than Consort. It is
weak on mildew, yellow rust and brown rust. It has a 6 rating for Septoria
tritici. Marketed by Elsoms. Shango X FD 89034.23(Florimond Desprez) 101.
Scorpion Group 2. A wheat positioned
at the top end of this category. Hard endosperm wheat positioned against Option
in the market place. Does manage to outyield both Xi19 and Option in the drier
East of England and hence has a specific recommendation for the East. Not NIAB
listed. Standing power reasonable,
excellent on mildew and yellow rust and good on brown rust and septoria
nodorum. Septoria tritici rated at 6. Not for early drilling as it establishes
very quickly. Protein levels 11.5, Sp wt 75.9 and good Hagberg at 317-320. (Breeder
Advanta, W929029 X Cadenza,104)
Warlock 24
Group 2. A hard endosperm variety
which unfortunately last November was dropped from further development .It was
in many ways a similar variety to Scorpion and Xi19 and was developed from
similar parents. However it could not offer any further improvements to these
two varieties which eventually sealed
its fate. The speed of development of the variety was quite fast, offering good
levels of disease control. Standing power was average. No seed available.(Breeders Advanta
Cadenza X Rialto 102)
Except Group 2. A hard endosperm, stiff
strawed, late developing wheat. Ideal for relatively early drilling, but if
drilled too early, grain quality could suffer. Good resistance to yellow rust
as well as septoria tritici (7) and septoria nodorum (7). Weak on eyespot and
mildew. Excellent standing power. Quality aspects are protein med/high, Hagberg
very high and Sp.Wt very high. (Breeder
Nickerson Hereward X Torch)
Einstein Group 2. A
hard endosperm milling wheat which yields at or just above Option. Stiff straw
(7) with good all-round disease resistance. Standing rated at 7, eyespot 7.
Slow developing but because of standing rating do not sow too early. The
millers like this variety due to its inherent white flour. Alveograph data
shows the variety as similar to Charger which is extremely desirable for export
markets. Dilution of protein content due to its high yield potential may
require additional nitrogen application to achieve full specification. (Breeder
Nickerson. 103 NSL92-1670 X NSL90-1282)
Cordiale
(CPBT W 83) Group 2. Excellent quality bread making variety, ideal for both home and
export markets. It offers high yields on par with many leading feed wheats,
together with high specific weight and hagberg. Agronomically, it offers a
variety with short and very stiff straw with good mildew and yellow rust
disease resistance, however, it is weak on septoria tritici, brown rust and
eyespot. (Breeder CPB Twyford 102
Malacca X Cadenza X Reaper)
Tataros Group 2. Hard endosperm wheat with potential
bread-making quality, producing high yields both treated and untreated. Yields
are similar to Solstice. It is tall but stiff strawed with good all-round
disease resistance. The variety exhibits excellent specific weight (79.2) and
good Hagberg Falling Number (294). Limited seed will be available for
commercial evaluation in autumn 2003.
Nijinsky (WW46)
Group 3. Potential NABIM Group 3
variety. It is the highest yielding wheat variety available but
unfortunately, there will only be a limited quantity of seed available for
2003. It is a soft endosperm wheat with biscuit quality. Agronomically it is a
good standing variety and its earliness to ripen is similar to Claire. It
offers good disease resistance being slightly better on mildew than Claire but
a little weaker on septoria tritici. Sp. Wt. has been on the low side. (Breeder
Nickerson 106 Claire X Consort )
Arran (WW39) Group 3. A
soft milling variety aimed at the group 3 markets. It is biscuit wheat like
Claire. It is high yielding, the grain being suitable for the distilling trade
and it is most likely to be grown in the North East and Scotland for that
purpose. (Breeder Nickerson 102. Not on recommended 2003 list. Consort X Asset)
Deben Group 3. A soft endosperm feed wheat with specific
milling uses for cakes and batters. Although a group 3 type, it does not have
the same flour characteristics for biscuits as Consort and Claire, so should be
stored separately. Less well liked by the distilling and starch industries. It
has very high yields but rather weak straw and has given its best performances
on lighter, less fertile soils. Seems slightly less sensitive to rotational
position than Claire. It has good resistance to yellow rust, septoria nodorum
and septoria tritici but is somewhat susceptible to mildew and eyespot.
(Breeder Nickerson 104 (Hunter X
Buster) X Wasp)
Claire Group 3.
A soft endosperm variety with
good biscuit-making potential and a wide variety of end markets. It is probably the most popular variety
grown. It performs particularly well in
first wheat situations and on heavier soil types. It is slow developing and is
particularly suited to early drilling. Optimal yield when sown from early
September to end of October. Avoid as
second year wheat. It has good resistance
to yellow rust, brown rust, septoria nodorum, septoria tritici and eyespot but
is very prone to mildew. It should have high combining priority in wet harvests
due to low sprouting resistance. (Breeder Nickerson 101 Wasp X Flame)
Consort Group
3. Still widely grown, this is a soft endosperm
variety with several potential market outlets, including feed, biscuit, export
and distilling. It has short, stiff straw and does well as a second wheat. It
is slow developing and is suitable for early drilling. Very susceptible to
septoria tritici. Odd cases of yellow rust been seen in this variety (strain
Oxbow). (Breeder PBI 100 Riband ‘sib’ X
Fresco X Riband)
Heritage Group 3.
A hard endosperm wheat that meets the key overseas
requirements for bread flour. Heritage’s specific weight requires attention to
ensure it meets 76kg/ha. It offers good resistance to brown rust and eyespot
but is weak on mildew and septoria Tritici. (Breeder PBI 100
Charger X Equinox)
Goodwood Group 3. A soft endosperm biscuit variety
offering yields slightly better than Claire or Consort. Unfortunately this
small increase in yield was not great enough over existing varieties to attract
growers and so did not get onto the NIAB recommended list for 2003. It has good
resistance to rusts and septoria but is very susceptible to mildew and
fusarium. It has stiff straw. (Breeder Cebeco
101 Flame X Hunter)
Dickson Group 3.
A soft endosperm biscuit variety, offering slightly better
yields than Claire and Consort, but just below that of Nijinsky. It also has
better Hagberg and specific weight ratings than Claire and Consort.
Agronomically it offers a stiff strawed variety with a medium-slow primordial
development for drilling mid-Sept onwards. It has low ratings for mildew,
yellow rust, brown rust and septoria tritici. Requires a comprehensive
fungicide programme. (Breeder Cebeco
Abbot X Consort 104)
Robigus Group 3. Has
full UK recommendation. It is a soft-milling wheat whose treated yield has been
above the highest yielding feed varieties. It is suitable for the UK biscuit
and distilling markets and is suitable for export into the biscuit and blended
flour markets. It is suitable for all soil types and can be sown as a first or
second wheat, however its best potential is in the first year situation. It has
good resistance to mildew, brown rust, septoria nodorum and septoria tritici.
It is very susceptible to yellow rust and is attacked by the same race (Oxbow)
that attacks Consort, Wizard, and Hereward. (Breeder CPB Twyford 105
Z836 X 1366)
Napier Group 4. This a hard endosperm feed variety, which
has high treated yields and has preformed
consistently well in all situations. It is a high
tillering variety and may benefit from reduced seed rates. It has good
resistance to brown rust but is susceptible to yellow rust, septoria tritici
and fusarium ear blight. It gives grain with a low Hagberg Falling Number.
(Breeder PBI 103 Hussar X Lynx)
Gladiator
Group 4. A very high yielding hard
feed wheat with high specific weight. It has short, stiff straw with a standing
power of 8. Overall disease resistance is good, its only weakness being
septoria tritici. Initial trials indicate it is suited to both the early (2nd
week September) and late drilling positions. (Breeder PBI Falstaff x Shannon)
Tanker Group 4. A
hard endosperm feed variety with very high treated yields and short, stiff
straw. It has given high yields in most situations. It has good resistance to
brown rust but is susceptible to septoria tritici and nodorum. It has given
grain with a moderate specific weight. (Elsoms 103 PG Beaver X Zodiac)
Savannah Group 4. A hard endosperm feed variety with high
treated yields, which likes high fertility situations. It is a high tillering
variety and may benefit from reduced seed rates. It has good resistance to
mildew and brown rust but is susceptible to yellow rust and septoria tritici.
It has moderate straw length. (Breeder PBI 103 Riband X Brigadier)
Richmond Group 4. A
hard endosperm feed variety which has high treated yields, short straw and is
early maturing. It has generally good disease resistance including high
resistance to yellow rust and brown rust. It gives grain with a high specific
weight. Some potential for export. It has a high protein content for a feed wheat.
Not on 2003 recommended list. (Breeder
Cebeco. 101 Brigadier X Flame)
Access Group 4. A
hard endosperm feed variety, which has very high treated yields, short straw
and good resistance to brown rust. It is susceptible to septoria tritici and
yellow rust (3), the same strain that Madgrigal, Napier and Equinox are
susceptible to. It has a large grain with moderate sp.wt. and a low Hagberg
Falling Number. Contender for Tanker’s position. Expensive to grow. (Breeder
CPBT 104 PG 90-15 X 91-6)
CPBW
87(Quest) Group 4 This variety has been submitted
as a candidate for the recommended list. It is a high yielding feed wheat with large
grain similar looking to Riband. Agronomically not one of the best on disease
resistance - yellow rust could well be one of its major problems. It is a high
input high output variety. It is short and stiff and reasonably early to
mature. No seed available until 2004. (Breeder CPBT Hudson X N4/35)
Istabraq(
WW47) Group 4 This variety is a very high yielding, soft endosperm wheat
with good all round
disease resistance.
Agronomically it offers medium level protein and specific weight with low to medium
Hagberg Falling Number. Mildew is its only weakness as regards disease with a
rating of 5. Standing power; straw length and maturity are 1 point below
Claire. (Breeder Nickersons Claire X Consort 106)
