GROWER SUMMARY
Headline
The introduction of new Autumn and Winter cauliflower cultivars has again increased Grade
1 marketable product, many being over 10% above standard cultivars based on 25315
plants/hectare (10249/acre) for the Autumn cultivars and 21193 plants/hectare (8580/acre)
for the Winter cultivars. Potential income can be increased by £890/Ha. This is a real
possibility with many producers now on a fixed price for their produce.
Background
Duchy College, working in partnership with seven national seed houses and local growers,
have carried out the evaluation of commercially available Autumn, Winter Cauliflower and
Spring greens cultivars over the past 19 years.
Initially introduced into the confidential/screening Trials and then within the commercially
available trials, each cultivar has been recorded and evaluated year on year. With the
improvement in plant breeding and new cultivars being introduced these need to be
assessed alongside current and established varieties in order to compare yields and quality
of produce.
With improved uniformity, disease resistance, and curd protection the need to compare with
current cultivars is even more important in order to plan the production of the crop to meet
market requirements and provide the best returns to the grower.
Results
The following cultivars are of most interest to the industry. Some are new introductions to
compliment cultivars that have been grown as the standard cultivars for specific production
periods.
Overall the 2014-15 season was one of two contrasts, the early Winter Cauliflower varieties
heading from early November onwards were in the main below average yields of Class 1,
due to the warm Autumn, whereas those varieties heading from February through to June
2015 were well above average yields, with some over 80% Class 1.
Transplanting conditions in July 2014 were very favorable with no delay in planned planting
dates and the crop established well. A late attack of cabbage root fly in late August/early
September weakened some plants initially however these soon recovered and growth was
rapid in September and October.
Agriculture and Horticulture Development Board 2015 6
The Trials were transplanted on the 10th and 18th July, similar to previous seasons. The
main bulk of commercial growers transplant from late June to early August.
As a result of higher than normal temperatures in September and early October 2014, a
number of early heading Winter Cauliflower cultivars produced both white and green bracts
in the curds, down grading produce to Class 2. Cultivars normally harvested early
November where 3 weeks ahead of schedule as a result of the mild autumn.
Commercially there was a market for this produce however in times of peak supply these
may not always be marketable.
The later transplanting date proved beneficial as there was a marked reduction in bracted
curds in nearly all cultivars.
Many of the late autumn cultivars performed well despite the weather conditions as can be
seen in the top performing cultivar table below.
Results over several seasons will need to be considered when selecting cultivars for
production. Full information on all cultivars can be found in the Full Trial Report.
Comments on curd protection, leaf colour, disease resistance/susceptibility, uniformity,
curd colour and density, suitability for various markets, defects and ease of harvesting are
found in the Full Trial report in the Appendices.
The Spring Greens trial was planted into good conditions on the 9th September 2014 and
produced high quality greens, some being harvested in early December and the later
cultivars in early February.

Late heading Winter Cauliflower 2014-15 Top performing varieties
These plots were transplanted on the 10th July 2014 aiming to head in the period April
through to late May 2014. Over recent seasons there has been a shortage of cauliflower for
this period which has resulted in the increase of imported produce to maintain supply to the
various market outlets. Although fixed price returns to the grower over this heading period
are not guaranteed there is scope to aim for this market share.
Transplanted at 21193 plants/hectare (8580/acre)
Some cultivars also produced larger curds that are not included on the table below. For
example the cultivar Tenfold produced 1889 trays/ha of 6 heads/tray.

The trials were undertaken at Trevarnon Farm. Gwithian, Cornwall. The soil type being a
sandy clay loam. The site is south facing and is part of a farm rotation based around
Brassicas, cereals and grass break crops. The farm has traditionally grown Brassica crops
supplying both the multiple and local markets. The trial itself is treated as a commercial crop
undergoing similar field operations as the commercially grown crops. The cultivars are
harvested twice a week on a similar basis as commercial crops on the farm.
Agriculture and Horticulture Development Board 2015 10
Main conclusions
All of the cultivars that have performed well during 2014 – 15 are commercially available to
growers, each with their own characteristics, traits and qualities. The large number of
cultivars available enables growers to select suitable cultivars for their production systems,
which vary from farm to farm and area to area. The cultivars available ensure continuous
supply complimenting each other throughout the production period. However, there is a
continuous need to improve output and quality, especially in the production period between
late December and early February when yields can be lower. There have been a number of
new introductions over this period, which have performed very well alongside established
cultivars.
Trials have also been undertaken where a number of confidential cultivars from a range of
seed companies have been assessed with some new named cultivars being introduced
into the commercially available cultivar trials for 2014 -15 and a number to follow in
subsequent years. There is renewed interest in the late heading cultivars for the heading
period of April and into mid-May.
The inclement weather patterns of both the 2012-13, 13-14 and 14-15 seasons has enabled
growers to observe those cultivars that have performed consistently despite the inclement
growing conditions. 2012-13 and 2014-15 proved to be one of the highest yielding seasons
whereas the 2013 -14 season was one of the poorest yielding seasons in the last 20 years.

FULL TRIAL REPORT
Introduction
Working in partnership with a number of national seed-houses the trials have enabled the
evaluation of commercially available Autumn, Winter Cauliflower and Spring Green
cultivars, in order that improved cultivars can be assessed alongside current and
established cultivars to improve yields, quality of produce and continuity of supply.
The Autumn Cauliflower trial compared established cultivars alongside new introductions for
the heading period of early October to late November.
The main Winter Cauliflower trial compares cultivars transplanted in early and late July and
provides detailed information on the advantages/disadvantages of staggered transplanting
dates, which is commercially practiced in order to maximize the potential of some cultivars.
This trial covers cultivars heading from late November through to April.
Increased interest and opportunities to market later heading Winter Cauliflower has seen a
number of new introductions for the May - June period and these have been evaluated with
some cultivars performing well.
The Spring Greens trial compares commercially grown hybrid cultivars transplanted
alongside the traditional Wintergreen cultivar. These are then assessed for suitability as
greens being harvested December to March depending on the cultivar and season.
The Cauliflower trials provide detailed information on each cultivar including:-
Harvesting period. 10%, 50% and 90% harvest dates.
% Grade 1, Grade 2 and unmarketable produce.
Marketable yields.
Comments on any defects, including disease tolerance especially for Xanthomonas
and mildew, pest presence, and the suitability for the various market outlets.
Evaluation on the ease of harvesting, packing, uniformity, depth and quality of curds.
Comments on curd protection, leaf quality and crop growth.

Discussion
The top performing cauliflower cultivars highlighted within the results section, normally
identifies cultivars that have performed above the average yield of 75% Grade 1. Each 1%
above this average yield increases gross income by £85/Ha based on a price of 40p per
cauliflower.
Many of the Autumn heading cultivars produced well above 70% Class 1 with some cutting
out over 85%, although the price to the grower is much less than the Winter cauliflower
price. A larger planting density per hectare would increase yields and returns even at a
lower price to the grower.
Conclusions
Within the autumn and winter cauliflower cultivars, a number of seed houses have
introduced numbered cultivars which have performed well alongside established and
recently introduced cultivars. As with all new introductions these need to be evaluated over
several seasons to ensure consistency within various growing seasons. Those that have
done well this season include the following:-
Monsanto 5965 Mid October (Harvest period)
Monsanto 5697 January/February
Nickerson AE 6272 February/March
A.L.Tozer 2067 Early/Mid March
A.L.Tozer 2038 Mid/End March
Nickerson AE 9307 Late February/March
Clause CHF 12-273 Early April
A.L.Tozer 2072 Mid April
A.L.Tozer 3007 Mid May
It is to be noted that each cultivar performs differently from season to season, however data
is available over the past 19 seasons which provides a basis upon which growers can make
an informed decision on which cultivars to grow to provide a continuous supply.

Technology transfer
The trials are harvested twice a week and results are updated weekly on the following
website http://www2.cornwall.ac.uk/research/herring/default.asp
Open days were held in December 2014, January and March 2015 where up to date
information was made available to growers and representatives from the industry. A
growers evening also took place on the evening of the January meeting to update growers
on current work in regards Brassica developments within the Seed houses represented in
the Trials.
