CAROSEM OPEN DAYS – OCTOBER 2016

CAROSEM OPEN DAYS – OCTOBER 2016

Following the management transition from Carosem BV (Holland) to Carosem GmbH (Germany a Field Trials/Open Day event was held at Ooltgensplaat in the province of South Holland ( Holland ), an area characterized by sandy soil,  25th to 27th October being planned as  140 days following seeding on 08/06/16.

The event was held to showcase varieties of carrot to distributors, sellers and growers for the world wide market.

Material was grouped in the following typologies:
–    Chantenay
–    Bunching
–    Early Nantes
–    Slicing
–    Industry

The field trials were designed for ease of comparison and evaluation in each typology.  There was no chemical compound treatment of plants in order to evaluate the behaviour of each variety against diseases, this strategic decision allowed for clear and unambiguous results thus giving visitors an opportunity to observe first hand different agronomic performances.
At the end of the three days visitors agreed that several Carosem F1 carrots, belonging to each typology, showed interesting agronomic performance compared to the standard, in particular the best hybrids of the Carosem portfolio were:

CHANTENAY TYPE:
CA 11147 – a new hybrid for Carosem, it showed a nice shape, size and root uniformity, with excellent colour and smoothness of root surface.  This variety has amazing green leaves and good tolerance to Alternaria dauci.

BUNCHING TYPE:
In this segment, where plants (root + leaves) must not be longer than about 60cm at harvesting, Carosem propose three hybrids:
CA 13-643 – an early variety (65-70 days to maturity)
Calibra and CA 2012 – products suitable for late sowing.

EARLY NANTES TYPE:
In this group, material with a life cycle of 90 days, Carosem identified three main new hybrids with interesting potential:
CA 10759 – good root uniformity and tolerance to Alternaria dauci
CA 9546 – excellent smoothness of root surface, shape, size, colour, round tip and uniformity.  Moreover, this hybrid showed good green top colour and an excellent tolerance to Alternaria dauci.  The added value of this variety is that at an advanced stage of testing these results were in several Countries, thus confirming its potential in different environments.
CA 11197 – another hybrid that showed excellent smoothness of root surface, shape, size, colour, round tip and uniformity.  This variety was especially appreciated in Brazil for its high yield.
Also, the current commercial products Cestas and Katop confirmed their agronomical performance and root characteristics with good colour and shape.  Cestas has good tolerance to cracking and the leaves of Katop are more tolerant to disease.

NANTES TYPE:
Many varieties received positive feedback from visitors, in particular the following five new hybrids are chosen:
CA 9647 – for its plant vigour, excellent tolerance to Alternaria dauci, leaf and root colour, nice smooth root surface and excellent yield.  As for CA 9546 the added value is the advanced testing in several Countries, confirming its potential in different environments.
CA 678 – for its root shape, size and colour, with an excellent root surface.
CA 444 – for its root colour, nice smooth root surface, root shape and size and good yield.
CA 12414 – for its excellent tolerance to Alternaria dauci,root colour and nice smooth root surface.  It produces slightly longer roots of a nice shape.
CA 10829 – is characterised by a medium colour leaf but with optimum top vigour and an excellent tolerance to Alternaria dauci. The roots have a nice colour and smoothness with good shape, size and yield.
In addition the commercial products of  Bengala and Bentley confirmed their agronomical performance and root characteristics, like colour and shape, their leaves showing tolerance to disease.

SLICING TYPE (NANTES/BERLICUM)
Plants in this typology produce long and cylindrical taproots which are sold whole on the fresh market or for slicing in rounds in the factory.
CA 12443 – produces very long and cylindrical roots (26 – 28cm) with good uniformity and a smooth surface.  The top leaf is healthy with a strong disease pressure.  These agronomic traits guarantee a high yield, both in the field and for  the industrial process.
CA 12447 – is similar to the previous hybrid but with a better top leaf, however a very small percentage of taproots show some cracking lesion.
DO 175 – characterised by long, very smooth and cylindrical roots with uniformity of shape and size. The foliage is health and erect and the yield high and of excellent quality.
Altantis is our important commercial variety for this typology, and confirmed all its qualities in field performance and final yield, with great general uniformity, nice root shape, size and colour, and excellent smoothness.

INDUSTRY TYPE (NANTES/BERLICUM
Plants in this group must have a high dry matter and a very deep colour.
Our main hybrid for this section is:
CA 723 – the field trial confirmed good performances already seen in trials in Northern Europe.  The roots are long (28 – 30 cm), of a conical shape, great deep colour and high dry matter content (15.6%). The foliage is healthy, withstands pressure from Alternaria dauci, is erect and has a dark colour.
CA 8295 – is similar to CA 723 but with a smaller top and and shorter life cycle.

To conclude.
The Open Days allowed visitors to evaluate the many hybrids presented, with positive feedback and Carosem believes they have a potential portfolio of products for the main commercial sector needs.
Before introducing new material to the market Carosem will continue to undergo field trials in order to evaluate plant performances in different environmental conditions, soil textures and agronomical practices.
