RUTGERS NEW VARIETIES
How can I get these new cranberry varieties?
There are two ways to purchase the foundation-level, virus indexed plant material of the Rutgers New Varieties:
- Buy unrooted stolons from Integrity Propagation (IP) and root them yourself. ( Mullica Queen, Crimson Queen, Demoranville only)
- Buy plants already rooted and nurtured from Integrity Propagation.
Which variety should I select?
If color is a priority, Crimson Queen, Demoranville, or Haines would be the best choice. Mullica Queen’s color is similar to Stevens. Mullica Queen has a diverse genetic background with impressive production. Scarlet Knights are particularly suited for fresh fruit. Welker is especially suited for cooler climates of the Pacific Northwest. All Rutgers varieties have been tested over many years, in replicated field plots, in multiple growing regions, before they were released for commercial production. If growers wait to see how the neighbor’s beds do, they will miss out on opportunity.
What is the cost of buying stolons?
Please call for pricing.
Are there self-propagation guidelines?
Yes, IP and Rutgers will provide valuable suggestions to assist propagation with your order.

WHY MOWINGS AND PRUNINGS CANNOT BE USED FOR ROOTED CUTTING PROPAGATION
Why should we use rooted cuttings to establish a new bed when it’s much easier to press in vines?
The cost of foundation-level virus-indexed plant material is about the same or less than non-certified mowings. Sacrificing your own crop to produce large volumes of vines for a new planting may not be economical because of the high productivity of the new varieties. The cost to scrutinize mowings or prunings to a similar extent of that done by Integrity Propagation (i.e. DNA and virus-testing) would probably exceed $500,000 per ton. You may not like what you find. After growers become familiar with rooted cutting technique they usually prefer this method because of rapid establishment and purity
Why can’t I root cuttings from mowings?
Rutgers does not allow taking cuttings from the initial bed and rooting them using the “rooted cutting technique” to establish a new bed because of the potential of volunteers from seedlings. These seedlings that survive are vegetatively aggressive and produce volunteers that end up contributing disproportionately to the next bed established. One seed with one runner can produce as much as 20 or 30 sq. ft. of an off-type volunteer in the new bed. Only Foundation Level Virus Indexed Stolons can be used for rooted cutting propagation.
WHY USE ROOTED CUTTINGS TO ESTABLISH A PRIMARY FIELD PLANTING
What is the cost of buying rooted cuttings from Integrity Propagation?
The cost is $8,300 – $11,000 per acre depending upon how and when they are grown. The most inexpensive way to grow plants is to root them in open trays.
How are the rooted plants sold?
Winter Plants are greenhouse grown, planted mid-February, and are available for shipping beginning mid-May.
Spring Plants are rooted outside in the spring, and are usually available for sale later June or early July.
Inventory Plants are Spring Plants remaining in our inventory to be planted early spring the following year.
There are 2 tray types:
96 Cell Tray has 96 plants growing in individual tapered cells which are usually preferred for mechanical transplanters.
Open tray has 128 plants growing without separation in one flat, usually producing larger plants with a greater root system that must be pulled apart for transplanting.
What is the cost comparison between planting rooted cuttings and conventional planting?
One plant per square foot cost about 50% of two tons of vines. The rooted cuttings usually established about twice the ground covering the first year’s growth. Rooted cuttings have well-established roots at the time of transplanting. Therefore, the new planting is eligible for a herbicide program long before conventional propagation.
HOW TO PLANT ROOTED CUTTINGS
How many plants should I plant per acre?
The minimum recommendation is 1 plant per sq. ft. or 43,560 plants per acre.
Some growers do feel that planting at higher density helps with weed control and increases yield in the 2nd and 3rd year. Some mechanical planters are set to plant at a greater density.
How early in the year can I plant the rooted plants into the bed?
Plants from our Inventory can be planted as early as you can get on the bed to work. The earlier the better, this is an advantage to plants purchased from inventory.
When is it too late to plant?
Some of our customers have successfully planted rooted cuttings as late as September and October. However, we do not recommend planting later than late August so as the plants will develop more root mass to protect them from wave displacement in flooded beds.
How should we plant rooted cuttings?
Cranberry growers use a variety of machines to efficiently transplant rooted cuttings into their beds.
A Sfoggia transplanter (or machines of a similar design) is one viable method. Each carousel being filled by a worker supplies plants to two rows simultaneously. Growers report that each worker riding the transplanter will plant up to 20,000 plants per day. These transplanters usually require use of the individual tapered cell trays.
Several growers have built a 9 row semi-automated “self transplanter”. Contained within each row is a worker, a planter shoe and two packer wheels. This transplanter will plant the individual tapered cells or the larger irregular-shaped plants from open trays and plant about 1½ acres per day. For more information regarding transplanters in your specific region, please contact Integrity Propagation.
Can I plant more than 1 variety in the same bed?
The license only requires a reasonable distance of 2 feet between varieties. The sections should be marked as to the varieties planted. Separation strip should be free of unwanted materials and weeds, as much as possible.
How deep should I plant rooted cuttings?
Rooted cutting should be planted deeper than they were in the tray. This will facilitate rooting of new shoots. IP provides a planting diagram with the orders.
After planting rooted cuttings, how much and how often should I fertilize?
IP will provide detailed fertilizer recommendation with the plant material that take your specific circumstances into account.
How often should I irrigate the beds?
Rooted cuttings are very resilient. Keep the bed moist but not wet for this would discourage root growth. Usually growers water new beds every other day to twice per day depending on sun intensity, temperature, and wind conditions.
When will you ship my rooted plants?
We can ship them whenever you are ready to receive them.
ATTRIBUTES OF THE RUTGERS NEW VARIETIES
What are the actual yields for Crimson Queen, Mullica Queen, Demoranville, Haines and welker reported by growers who have already established beds?
Growers have reported yields well over 600 barrels / acre for all three varieties. Fresh fruit variety, Scarlet Knight yields are usually slightly higher than Stevens
What is FLVI?
FLVI, “Foundation Level Virus Indexed” means that 100% of the plant material has come from a fingerprinted vine and each pot that the vines were grown in was tested and free of viruses commonly found in cranberries. Only plant material sold by Integrity Propagation is FLVI.
RULES ABOUT SELF PROPAGATION USING MOWINGS OR PRUNINGS
If we buy the minimum acreage can we use it to establish more acreage?
Yes, Rutgers only requires that growers buy one acre. NOTE: an additional propagating license is required to propagate Haines Welker or Scarlet Knight by conventional propagation. Contact Integrity Propagation for Details.
Growers may produce fruit or prunings and mowings from their initial field planting to plant secondary field planting or even subsequent field planting.
Rutgers does not regulate the density of conventional propagation of subsequent field planting, when growers are using mowings or prunings from their own beds. However, Rutgers recommends that growers always use plant material as close to the initial foundation level plant material from Integrity Propagation as is possible. Rutgers prohibits rooted cutting propagation with any plant material other than foundation level plant material; again, this is because of the potential to exponentially reproduce off types which are inevitably found in mowings.
Why doesn’t IP raise Foundation Level Stevens plant material?
The variety Stevens has been an excellent variety in cranberry business and also served as an excellent parent in its pure form, however, there is not much of an incentive to create Foundation Level Stevens because their productivity is much lower than the Rutgers New Variety releases.
Do you ship plants to British Columbia?
Yes, we have developed methods of economically shipped plants to BC, using one-way-shipping disposable pallets. The cost to transport plants to BC is reasonable. One trailer using one-way-pallets holds about 8 acres. We regularly ship to Wisconsin, Massachusetts, Quebec, and New Brunswick using shipping carts that are returned to IP.
When is my Rutgers Royalty payment due?
The Royalty payment is due 30 days after planting.
How long after planting a bed will it be ready for production?
Some growers will harvest fruit in the fall, and replant using rooted cuttings in the spring of the following year, resulting in only one year of total production loss. In some of these beds, the first harvest of the new variety in the second year exceeds the production before the renovations.
