HGCA Recommended Lists (RL) 2013/14, published today, now contain resistance ratings for fusarium ear blight in spring wheat and ramularia in barley.
In total 41 new varieties have been added to this year’s Lists, while 24 varieties have been removed.
The large number of varieties added and removed this year is due to breeders successfully bringing forward varieties with high yields compared to current varieties.
Wheat
There are ten new wheat varieties which include a new nabim Group 2 breadmaking variety, three nabim Group 3 soft varieties for biscuit-making, four soft feed varieties and two hard feed varieties.
Chilton is a nabim Group 2 variety with a similar yield to KWS Sterling. It has a high specific weight and performed well in the difficult 2012 season. It is a stiff-strawed variety but attention to detail will be required to manage brown rust, eyespot and septoria tritici. The variety is provisionally approved for ukp export.
KWS Croft was selected for the UK, meeting Group 3 biscuit requirements and is also provisionally approved for uks export. It achieved a very high yield but has a low Hagberg. It is less suitable for distilling and is weak-strawed. The variety has high resistance to yellow rust.
Monterey was selected for the UK, meeting Group 3 requirements, and is also provisionally approved for uks export. The variety is high yielding, has a high specific weight but is rated as poor for distilling.
Delphi was selected for the East, meeting Group 3 requirements and is also provisionally approved for uks export. The variety is high yielding, has high resistance to yellow rust and brown rust and a rating of 7 for fusarium, but attention is required to control eyespot. It is acceptable for distilling.
The four soft feed varieties Leeds, Myriad, Revelation and Cougar all bring different characteristics for growers to choose from. Leeds was the highest yielding of the four varieties with a high specific weight and a rating of 7 for yellow rust and fusarium, but with attention required to manage its susceptibility to mildew. The variety is rated as good for distilling and its agronomic characteristics and high yield in the North will make it of interest in that region.
Myriad has a high yield and high resistance to yellow rust. It is acceptable for distilling and has provisional approval for uks export. Revelation is a later maturing variety rated as good for distilling. It is stiff strawed and has a high yield both treated and untreated. It has high resistance to both yellow and brown rust and also eyespot, with a high rating of 8. It is also rated 7 for fusarium.
Cougar has a slightly lower treated yield potential and has low specific weight but it has the highest untreated yield of all varieties on the Recommended List and an impressive array of resistance to disease, including a 7 rating for septoria tritici. The variety is late-maturing and performed less well in 2012 trials. It is unsuitable for distilling, and attention is required to control eyespot so may be of less interest in Scotland.
Two hard feed varieties selected are KWS Kielder and Dickens. KWS Kielder is the higher-yielding of the two and is close to the top yielding feed variety, KWS Santiago. It is resistant to brown rust but susceptible to yellow rust, so attention to detail is required with fungicides to achieve the best yield from the variety.
Dickens also has a very high yield and is earlier maturing than KWS Kielder with a high yield in the north. It has high resistance to yellow and brown rust but attention is required to manage eyespot.
Varieties removed
Six wheat varieties have been removed from the HGCA Recommended List. These include casualties to new races of yellow and brown rust which first appeared in 2011. Torch fell below the minimum standard for yellow rust and Stigg for brown rust, other removed varieties are Battalion, Humber, Ketchum and Warrior.
Barley
Seven new winter barley varieties have been added to the 2013/14 Recommended List.
The agronomic performance of malting varieties has taken a step forward in yield with four new varieties with malting potential added to the Recommended List, Talisman, KWS Joy, Mezmaar and Soloman. Talisman is early maturing and has the highest yield of the four varieties with high resistance to mildew and rhynchosporium. KWS Joy will require attention for rhynchosporium. Mezmaar has high resistance to rhynchosporium but attention will be required to minimise lodging. Soloman has good resistance to brown rust and relatively good straw strength.
Advances have also been made in two-row feed varieties. KWS Glacier achieves recommendation for the UK. It is stiff-strawed and achieves the top yield of feed varieties, toppling Retriever from this position, but with a superior specific weight. Growers will need to watch mildew but it scores 6 ratings for brown rust, rhynchosporium and net blotch. The variety has performed particularly well in the East.
Two varieties achieved regional recommendation. Matros is recommended for the East region and California for the West. Matros is stiff-strawed and achieved 7 ratings for mildew, brown rust and rhynchosporium and has a good untreated yield. California is a stiff-strawed variety with a yield similar to KWS Cassia in the West.
There is a good advance in spring barley yields of both malting and feed varieties. Sanette, which is potentially a future malt brewing variety was recommended for the UK. It has good resistance to mildew but attention will be required to manage brown rust. New for the 2013/14 Recommended List are ratings for ramularia and Sanette shows good resistance to this disease.
Glassel is potentially a future malt distilling variety and achieved a higher yield than Shuffle and Concerto. It has good resistance to mildew but attention will be required to manage both rhynchosporium and brown rust.
Seven feed spring barley varieties were added to the list. Tesla, Crooner, KWS Orphelia, Kelim, Natasia, Montoya and Rhyncostar. All have yields that match or better than existing varieties. All have high resistance to mildew with Tesla and KWS Orphelia having above average resistance to rhynchosporium.
Varieties removed
Three winter barley (Element, Pelican, Purdey) and two spring barley (Oxbridge, Summit) varieties were removed from the List.
Oilseed rape
East/West region
There are two new high-yielding open pollinated (conventional) winter oilseed rape varieties for the East/West region. Rivalda is the higher-yielding of the two and has good resistance to lodging. Quartz is slightly lower yielding but has similar lodging resistance and excellent resistance to phoma stem canker with a rating of 9.
Three restored hybrids were recommended for the East/West, Marathon, PT211 and Avatar. Marathon is the highest yielding of the three with good resistance to lodging and stem stiffness but it is susceptible to phoma stem canker. PT211 and Avatar both have good lodging resistance and standing ability. Avatar is susceptible to phoma stem canker.
Troy is a semi-dwarf restored hybrid variety which brings together a package of good yield, a short stem, stiff stem and good resistance to lodging.
DK Imagine CL was added to the Oilseed Rape Descriptive List for the East/West and the North. This is a specialist variety and is the first variety with tolerance to imidazolinone herbicide (IMI tolerance). This variety will provide benefits to growers in giving greater flexibility to manage weeds but growers should be aware that options for the future control of IMI tolerant volunteers may be limited.
North region
There are three new open pollinated (conventional) varieties for the North region, Anastasia, Boheme and Pendulum. All have high yields and good resistance to lodging. Anastasia is the highest yielding of the three with good resistance to lodging and stem stiffness.
Five new restored hybrid varieties were added to the North Recommended List, PT208, Raptor, Shot, PT211 and DK Expower. All are high yielding with good resistance to lodging.
The restored hybrid semi-dwarf variety Troy was added to the North Recommended List. Troy achieves a high yield, sitting second top in yield of all the North varieties with good resistance to lodging and stiff stems.
Varieties removed
Eleven varieties were removed from the two Winter Oilseed Rape Lists. These were Palace, Expert, Lioness, ES Astrid, Hammer, PR45D03, Castille and Mendel in the East west region, whilst Lioness, Mendel and Palace were removed from the north region.
Oats
No new winter or spring oat varieties have been added to the List.
Two winter oat varieties (Hendon, Brochan) were removed.
