Winter rape
Conventional Open Pollinated Varieties
Castille
The biggest selling conventional rape in the UK and the original low biomass variety, combining consistent high yield with excellent disease resistance. Available in four million seed packs, allowing seed to be drilled by numbers and not weight. Yearling seed available for guaranteed early delivery.
Breeder: Dekalb
Catana
The highest yielding variety on the 2009 HGCA Recommended List for the northern region. Exceptional gross output in the northern region where it`s the obvious choice for all growers (except where club root is present). In the south, Catana is an ideal partner variety for Castille, with higher gross output potential enhanced by its 45.1% oil content. Catana has excellent autumn vigour to aid establishment. Yearling seed available for guaranteed early delivery.
Breeder: Dekalb
DK Cabernet
Currently the highest gross output candidate in the Recommended List trial, this variety is believed by the breeder to be the natural successor to Castille. 46.3% oil content, massive seed yield and sound agronomics give it the highest merit score ever recorded.
DK Cabernet is 12% higher for gross output than Castille.
Breeder: Dekalb
Vision
Newly added to the HGCA Recommended List, this is the highest gross output conventional variety on for the southern region. It is a medium height, with stiff straw and an upright canopy at harvest. It has high oil content and superb resistance to both light leaf spot and Phoma (stem canker).
Breeder: Senova
NK Grandia
A new conventional variety currently in National List 1 in the UK. It`s performing exceptionally well in all official trials in Europe. Seed yield is the same as Vision but it has a much higher oil content.
NK Grandia is short-strawed with high resistance to lodging. It has early flowering and maturity dates along with excellent disease ratings. Available in very limited quantities.
Breeder: NK Seeds
Hybrid Varieties
Dimension
Dimension is the first of a new generation of hybrids from the breeder of Flash and Lioness. It has been newly added to the 2009/10 HGCA Recommended List. Dimension combines the yield potential of Flash with an ultra high oil content of 45.6%. Shorter and stiffer than some other hybrids with excellent disease resistance. The ideal partner variety to Excalibur.
Available with Cruiser OSR seed treatment to give protection against turnip yellows virus and downy mildew, as well as the usual control of cabbage stem flea beetle.
Breeder: DSV
DK Secure
Fully recommended, this is an unlodgeable semi-dwarf rape, with yields similar to Castille. DK Secure is the first in a new line of taller semi- dwarf types with sufficient biomass to allow them to yield well, but with the short stiff stem necessary for early drilling on high fertility sites.
Breeder: Dekalb
Excalibur
This has taken the market share for hybrid varieties to new levels, as it combines high yield with outstanding vigour and unique early maturity - not to mention much improved disease resistance. Whilst not a low biomass variety, Excalibur does combine shorter straw than most hybrids with good stem stiffness.
Breeder: Dekalb
Vistive Varieties
Vistive
Vistive varieties produce premium oil with the high oleic. low linolenic (HOLL) content necessary for the industrial catering industry, where cooking oil must be stable at high temperatures for long periods. The varieties must be grown on land where the risk of volunteers is low to avoid contamination of the crop. It is suggested that a rotation of 1:4 or greater is required. Contracts with high premiums are available for growers with the necessary rotation.
Openfield is the leading merchant in the development of Vistive oil production, with 2009 seeing our fourth harvest. Demand for the 2010 harvest is very strong, so please contact your local Farm Business Manager for details.
V1410L
A high yielding, higher oil type with a more flexible sowing range than Splendor and excellent disease and straw characteristics, VI41OL attracts a premium of 17.5% of the base price (plus oil premiums).
