Advanced Berry Breeding Varieties

Attention Commercial Growers!

We continue to be excited about 3 raspberry varieties introduced in fall 2015 by Advanced Berry Breeding in the Netherlands.

These three red raspberry varieties have demonstrated the production potential double that of any other variety we have ever grown. Besides being high yielding, the fruit has excellent qualities.

The Licensing arrangements for these varieties will be more extensive than what we have traditionally handled:
• All commercial fruit producers must complete and sign a Fruit Producers License.
• Annual royalty payments will be collected on the linear meters of row under production.
• Quantities less than 5000 plants can be planted without an Annual License Fee and Annual Royalty payments, but do carry a plant royalty of $1.00 per plant.  A detailed Non Propagation Agreement must also be signed.

Imara® U.S. Plant Patent #46031

Imara® means ‘strong’ and this vigorous primocane raspberry variety bears that name with honour. For many growers Imara® is an easy to grow variety which brings high yields. The large and conical shaped fruit have a good quality and are easy to pick as well. The production of Imara® starts rather early; the harvest period falls shortly after that of Polka. The plants are vigorous and have small dark red spines, which do not interfere with harvesting of the crop. The plants form many laterals easily and flower buds are developed down almost the full length of the canes. To make picking easy and not too time consuming it is important to limit the number of Primocanes. Consequently the reduced crop size will make the fruit more visible and accessible for the pickers. 

The fruit of Imara® have a rather dark red colour and are shiny. The berries are conical shaped and large, with a fruit weight of 5 to 7 grams on average. They have a good flavour although can be rather dry. The berries slowly become a darker colour after picking and have a good shelf life. When ripe the fruit releases easily, enabling easy and quick picking and results in a very efficient harvesting performance. Imara® gives a very high yield. Just like Kweli®, Imara® shows a low susceptibility to diseases up to now. Moreover the variety seems to have a reduced vulnerability to red spider mite. The risk of an infection with fungal diseases can be reduced by using rain shelters.

Kweli® U.S. Plant Patent #46041

Kweli® is a primocane raspberry variety which is well adapted to production in most climates and growing conditions. The variety is easy to grow and gives very high yields. The round shaped raspberries have an excellent shelf life, making long distance transport possible. The combination of these attributes makes Kweli® a very attractive variety for many raspberry producers. Kweli® is a mid-season variety, with a harvest period slightly later than that of Polka. The plants are vigorous and develop laterals at all levels. It is important to reduce the number of growing Primocanes to keep the crop more open and compact. This makes the fruit more visible and accessible for picking. Kweli® has some eye-catching small green spines, but these do not interfere with picking. Kweli® produces round fruit with a middle red raspberry color. The fruit is large and usually weigh five grams or more. The fruit has a good taste, but can be rather dry. Kweli® has an excellent shelf life, the fruit only darkening slowly after harvest. A shelf life of ten days or more is possible. Kweli® raspberries can be harvested easily, the fruit releasing more readily when picking not too early in the morning. Kweli® is a highly productive variety.

Until now Kweli® has not shown any particular susceptibility to diseases. Possible infection with yellow rust (Phragmidium rubi-idaei) can easily be prevented by using rain shelters.

Kwanza® U.S. Plant Patent #46030

Kwanza® is a primocane raspberry variety which starts fruiting somewhat late in the season. The variety attracts attention because of the fruit size and the bright, orange red raspberry color. The berries have a good taste and a long shelf life. As picking is also easy and efficient, Kwanza® belongs to the top of the present range of primocane raspberry varieties. Kwanza® plants develop a compact and erect crop. They have big leaves and only a few small spines. Because of the limited number of basal shoots, the crop stays uncomplicated and the fruit can be found easily by the pickers. Kwanza® starts production about 10 to 20 days after Polka. Kwanza® fruit are conical to round, moderately shiny, and weigh six to eight grams on average. To retain the quality of the fruit skin, careful picking is required and it is recommended to start picking not too early in the morning. The moisture tension in the plant cells will be lower in the later hours of the day and the fruit will release better. Shelf life is excellent, the fruit retaining their bright and light color well. Kwanza is susceptible to sunburn as temperatures exceed 90 degrees. Kwanza® gives a high yield. To get an uncomplicated crop a relatively small number of canes per linear foot is required. A dense crop will bring smaller fruit and causes a decreased picking performance, while the yield will be only slightly higher. It is important to have a relatively dry soil during the night. This can be achieved by finishing the irrigation at the end of the afternoon.
